Environmental investigation report composition 400 words

In daily study, work or life, people will inevitably come into contact with or use composition, which is a kind of speech activity for people to express their thoughts in written form. I believe many people will find writing difficult. The following is a 400-word composition of my carefully compiled environmental investigation report for reference only. Let's have a look.

Environmental investigation report composition 400 words 1 With the progress of science and technology, many people have devoted themselves to the life of learning science and technology, but these people do not know how to protect the environment and throw peels and scraps of paper everywhere! At the gate of our school, many people, including our classmates, throw peels on the wasteland in front of us because they are not very particular about it and don't understand knowledge! I'll give you a photo of the unbearable land now: the last time I went fishing with Luo Heng and other students, just after I stepped into the land, a group of mosquitoes came at us crazily, and a burst of Hong Kong jelly beriberi came at us! We covered our noses and reluctantly walked to the stream to get water.

That water is more magical! Black makes my face black. I don't want to see anyone.

After receiving the water, I opened my eyes and saw the dirty garbage by the stream: discarded things such as plastic belts and plastic bottles! Do you know what plastic belts can do? Harvest 1 mu of land every year! In this way, the beautiful earth will eventually be destroyed like Mars! ! ! Who did this? Residents who live nearby, of course! As long as they have rubbish, they will fall here. As soon as the workers saw it, they set fire to all the rubbish here! Severe smog has destroyed the ozone layer that protects our planet. Without it, human beings will be exposed to 100% ultraviolet rays from the sun! If we protect our earth now, it can live longer and longer! !

Environmental investigation report composition 400 words 2 My family lives in Taishan District, where the air is fresh and sweet and the trees are lush, including camphor tree, locust tree, magnolia tree and willow tree. In summer, the trees are lush, which is a good place to enjoy the cool. The community is covered with clover and the lawn is covered with thorn grass, which is very beautiful.

Our community now has clean roads and beautiful environment, but when we first moved in, we were disappointed: the environment was not good, there were no green belts, there were few trees, and the roads were dirty and uneven; Some people plant trees, raise chickens and ducks in the open space, and put their cars wherever they want; The air pollution is so great that it smells bad when you open the window, and the road is dusty.

Why has our community changed so much? Through my investigation and visit, I finally found out the reasons: First, the community has vigorously strengthened the greening work, planting and pruning trees regularly every year, so that the greening area has been increasing. Second, the management of the community has been strengthened, people's awareness of environmental protection has been enhanced, and the behavior of destroying trees has been greatly reduced. Third, sanitation workers have increased the frequency of cleaning, and the sanitation situation has been greatly improved.

By consulting the information, it is found that trees are of great help to the environment. First, trees can absorb dust and carbon dioxide and purify the air. Second, trees can fix the soil and prevent soil erosion; Third, trees can reduce noise and are good for health; Fourth, trees can regulate the climate and increase precipitation. ...

It turns out that trees are so good for us. We must protect trees and make our green home more and more beautiful!

The other world is a paradise with beautiful environment.

There, the spring sky is as clear and blue as the wind's mother-in-law's washing, as blue as the sea, and there are a few white clouds floating. There are many trees planted there, lush everywhere, the water in the pond is crystal clear, there is not a piece of paper, and there is a lunch box. The ground is cleaner than home, and almost everyone has managed not to throw paper scraps.

There, in summer, unlike in China, people go to the barbecue shop to eat meat products such as chicken, fish and beef every day. There are only cabbage, fruit and other items in their street. They never eat meat products. The world is cool and everyone is very comfortable.

There, in autumn, leaves fall slowly in a rotation, and people consciously sweep the street with vacuum cleaners and brooms, oh! You must be surprised to ask, why do they vacuum the floor? Of course, it is to suck up dust to protect the environment.

It's very cold there in winter. Although the weather is very cold, they think the air there is particularly fresh.

Oh, you must want to go there after listening to my introduction! But the world may be abroad, or even further. But as long as we care about the environment and everyone protects it, maybe the environment of another world is in front of China.

With the progress of science and technology and the development of economy, human beings have done great harm to the development and utilization of the earth's resources: the forest has been sharply reduced, the land has been desertified, coal, oil, natural gas and other mineral resources have been overexploited, and a large number of species have been extinct ... The earth is scarred and crying.

A few days ago, the upstream water rushed into the Qianyoufang River, and the water in the river gave off a bad smell. I can smell this disgusting smell every time I go to school, and a large number of fish in the river die. In addition, some industries are called "three wastes", "waste water", "waste residue" and "waste water", which has caused great damage to our environment.

Faced with these things that damage the environment, our government has also taken preventive measures, such as establishing nature reserves, strengthening natural forest protection and plantation construction, and strengthening international cooperation. Laws and regulations have also been formulated, such as the Environmental Protection Law, the Marine Environmental Protection Law and the Water Pollution Prevention Law ... The United Nations has also established environmental protection organizations, such as the United Nations Fund for Nature, Friends of the Earth and Greenpeace.

I believe that in the next 20 years, the earth will be full of vitality, environmental protection will be better and China will become more prosperous. ...

White pollution is a unique environmental pollution in China. A large number of discarded plastic products can be seen everywhere in various public places. They come from nature and are made by human beings, but when they finally belong to nature, they are not easily absorbed by nature, thus affecting the ecological environment of nature. From the perspective of saving resources, plastic products should be recycled as much as possible, because the main source is exhausted oil resources, but the production cost of recycling at this stage is much higher than the direct production cost, which is difficult to do under the current market economy conditions.

Facing the increasingly serious problem of white pollution, people hope to find a plastic substitute, which can replace the existing plastic properties without causing white pollution. Degradable plastics came into being. The characteristic of this new functional plastic is that after reaching a certain service life, its chemical structure will degrade obviously under certain environmental conditions, which is harmless or less harmful to the natural environment.

For example, starch-filled plastics, first of all, the starch contained in it is rapidly decomposed by amylase secreted by microorganisms in the soil in a short time, which leads to the decline of the mechanical properties of the film. At the same time, the self-oxidant added in the formula reacts with the metal salt in the soil to generate peroxide, which breaks the chain of polyethylene and degrades it into small pieces that are easily swallowed by microorganisms, which are absorbed by the natural environment and play a role in improving the soil.

Environmental investigation report composition 400 words 6 Land is the foundation of human food and clothing. Today, with the high development of science and technology, the land has been destroyed unprecedentedly. Among them, soil pollution is like a soft knife, depriving a large area of fertile soil of its productivity.

Soil pollution mainly refers to the phenomenon that some harmful substances in the soil greatly exceed the normal content, and the land can not eliminate the influence of these harmful substances. Serious soil pollution will lead to crop growth decline, even wither and die, and these pollution consequences can be found in time. More soil pollution has no obvious performance, but it reduces the quality of agricultural products, especially through the enrichment of harmful substances by crops, which secretly harms the health of livestock and human beings. We must be highly vigilant.

Soil pollution mainly comes from domestic sewage and industrial wastewater, waste gas, waste residue, chemical fertilizer and pesticides. Domestic sewage and human and animal manure contain many nutrients that plants need. Irrigation with sewage or application of manure usually increases crop yield. However, pathogens, viruses, parasites and eggs in these wastewater and wastes enter the farmland and deposit in the soil, causing soil pollution. Human contact with contaminated soil and agricultural products can cause tetanus, epidemics, endemic diseases and parasitic diseases.

Once the soil is polluted, its influence is difficult to eliminate. Organic pesticides decompose very slowly, and heavy metals do not decompose at all. Even if the polluted land is no longer polluted, it will still contain high levels of harmful substances after three to five years, which can be enriched through the food chain and endanger human beings. Therefore, the plants on the heavily polluted land can not only be eaten, but also can not be used as feed or fertilizer.

Last weekend, my parents and I went to a lake near Zhaomushan and conducted a small-scale environmental investigation.

Let's go around the lake first. Not far away, we saw many bottles, pieces of paper, cans and so on. In the lake, there is a lot of rubbish on the roadside. The dustbin has been neglected for a long time, and it has all come out, and no one has cleaned it. Many people saw that the trash can was full, and no one reminded them, so they threw it on the ground. There are also many scraps of paper on the grass. There are piles of rubbish in the trash can. Some people throw it into the lake, some people throw it on the ground, and some people throw it into the trash can. Some picnics are over, and plastic bags and food scraps are not collected, which is very dirty.

I think the reason is that people's awareness of protecting nature is not strong, the concept of environmental protection has not been formed, public health awareness is not strong, plastic bags, scraps of paper, cans and so on are littered. It is suggested to set up a billboard on the lake or lawn, and dispose of the garbage in time, recycle the garbage in time, and remind people not to litter.

In addition, I suggest that city managers should also strengthen management and clean up scattered garbage in time. Remind people to pay attention to environmental protection in time and give certain punishment to litterers. For example, when they see that people who litter are caught, they have to clean up for a day to strengthen people's awareness of environmental protection.

Nature is beautiful. I hope people will stop destroying nature and make our home more beautiful.

On Saturday, some friends and I made an environmental survey in my hometown Wangzhuang.

Standing on the roadside, the first thing you see is a large number of discarded plastic bags, which is the so-called "white garbage". White pollution has a great influence on our lives, and many discarded plastic products can be seen in public places. They come from nature, but they are not easily decomposed by nature, thus affecting the ecological environment of nature. People hope to find a plastic that can replace the existing plastic without causing white pollution, but this cannot solve the fundamental problem. So I hope everyone can get rid of this bad habit-don't throw white garbage everywhere and make our hometown better.

A gust of wind blew, and the pungent smell came face to face. Looking up into the distance, it turned out that the factory chimney was "smoking". There are two big factories in Wangzhuang, which emit waste gas from morning till night. These waste gases contain a lot of harmful gases such as carbon dioxide and sulfur dioxide, which seriously affect people's health.

Children, caring for our environment means caring for ourselves. If people don't care about their environment, what will happen to our hometown in the future? Care about you, me and him, and the environment depends on everyone. Let's work together to create a good and comfortable living environment!

Anyone who lives in Jingguan Town will know that every day there is always thick smoke floating near the "big belly" river, and it also emits a pungent smell, which makes it difficult for passers-by to breathe. What is the reason for this phenomenon? Taking advantage of the May Day holiday, I made a detailed investigation and understanding of the whole pollution situation of this river with this problem.

After three days of understanding, investigation and visit, I found that the reasons for the serious pollution of the "big belly" river are as follows:

1. Every morning or evening, factories along the river discharge black sewage. Seen from a distance, the river looks like a black veil. And pieces of dead fish. The chimney of the factory has changed from brown to dark because of the long-term emission of black smoke, and the sky above has changed from blue to hazy grayish yellow.

2. Littering. Because there is no unified garbage dump, a lot of domestic garbage is thrown into the river, which makes the river full of garbage for a long time. However, so much garbage has not been dealt with by the relevant departments in time, which in turn makes the residents here feel helpless. They destroy rivers themselves, but they are troubled by the influence of river pollution on their lives.

3. Burning garbage. Environmentalists often burn garbage by the river because they are troublesome. The smell of burning garbage is unbearable, and all pedestrians pass by and leave in a hurry.

4. Automobile exhaust. Both gasoline vehicles and diesel vehicles will continuously emit exhaust gas during the combustion process, which is mixed with the smell of gasoline.

Environmental pollution has seriously affected the normal life of residents. For the sake of residents' health and safety, I hope the relevant departments will pay attention to this matter and solve these problems effectively.

Environmental investigation report composition 400 words 10 Today, my mother said that she would take me to a small park to play.

My mother was very happy as soon as she said it. She said, "The small park used to be beautiful and lovely, full of children's laughter, but now …" My mother seemed afraid to say it, so I asked her doubtfully, "Mom, what's wrong with you? Why didn't you say it? What does the small park look like now? " Mother smiled and said, "Son, you will know when you go." When I arrived at the small park, I opened my mouth and asked in surprise, "Mom, mom, how did this happen in the small park?" Why is the small park full of dirty and smelly garbage? " Mother sighed and said, "Because people have been throwing garbage, and no one has come to clean it up." I listened and said to my mother, "If they don't clean up, let's clean up." My mother looked at me and said, "My daughter has really grown up." I looked around to see if there were any brooms in the small park. I saw three brooms at the gate of the small park. I said to my mother, "Mom, look! There are three brooms there. " After that, my mother and I took a broom, put on a mask and began to clean the small park. Passers-by saw it and seemed to think: I can't lose to such a small child to clean the small park. Then he also put on a mask and picked up a broom to sweep with us. After our efforts, we finally cleaned the small park and the grass gradually stood up. Small blooms produce beautiful flowers. Mother said happily, "The small park is as beautiful as before!" "

Therefore, we should protect the environment, so that our life can be happier.

Environmental investigation report composition 400 words 1 1 Shaoxing is called "Venice of the East", so is the water in Shaoxing really good? That's not true. After investigation, it is found that the water pollution in Shaoxing is also very serious.

Take the ring river as an example. Although it is beautiful now, I used to be afraid to get close to people. Until the beginning of 1999, we seized the favorable opportunity of urban flood control project construction, and the Shaoxing Municipal Party Committee and Municipal Government made a decision to implement the comprehensive improvement of urban rivers, and put forward the idea of "giving full play to the power of society to govern the Gudu River". With a cost of 65.438+0.2 billion yuan and 270 days of construction, the ring river has finally become another beautiful landscape in Shaoxing.

How is water pollution produced? Mainly because of the older generation, or some citizens with lower quality. In the past, the river was clear, and old people often liked to wash rice, vegetables and even clothes in the river. Because it saves water and is convenient, it is normal for everyone to do whatever they want. In the long run, how can the river not be dirty? More importantly, water pollution not only pollutes the environment, but also affects people's health. Because people in some places are still drinking the water from that river, which has been used, and people's health is seriously damaged by drinking it.

So, how to solve the water pollution problem? It is important to change people, but it is more important to change the existing water pollution. It has become a reality that Shaoxing Sewage Treatment Plant connects all links of "reservoir-water plant-water supply-drainage-sewage treatment" into an industrial chain. But does this fundamentally solve the water pollution problem? I don't think so. Water is still being destroyed and pollution continues. It's still about the people. Only the people themselves realize the seriousness of the consequences of water pollution and know that water resources can no longer be destroyed and should be protected. At that time, there was no need for remediation, and water pollution would naturally disappear.

Let's take action, and I will try to eradicate water pollution!

Environmental investigation report composition 400 words 12 Bizhou Park is an oasis in Xiangxiang City, which is a good place for everyone to have fun. Our group chose this place for this "environmental protection" investigation.

On March 15 at 2 pm, I came to Bizhou Park with Chen Chenxuan and Huang. As soon as I entered the park, I saw several bosses eating cotton candy. One of them took a few bites and threw it away. I chased them and said, "Please throw them in the trash can." They gave me a look and left with a smile.

A few steps further, I saw a small animal shit on the grass. It was disgusting, so I didn't shoot anything. But there is still a lot of white rubbish on the grass, and the trash can is just a few steps away, watching helplessly

When I came to Xiaozhulin, I found that some bamboo was cut down. I guess they were taken home as clothes.

When I approached the square, I saw people sitting on the grass in twos and threes to rest. A child climbed hard on the peach tree, then climbed up and down, and then climbed up and put the mineral water bottle on the branch. Chen Yizhen said with a smile that the peach tree has become a "bottle fruit".

On June 16, my mother and I went shopping in the supermarket. When we were waiting in line at the checkout counter, my mother told me that the plastic bags for things were white garbage, not environmental protection bags. I observed it until we left, and I didn't see anyone shopping with an environmental protection bag. They all use plastic bags.

Through this survey, I found that littering and using plastic bags are only some people, but their awareness of environmental protection is not strong. I think we should act quickly to protect the environment and make our park more beautiful. As we can see, many people plant trees. I hope that the water in Lianshui is crystal clear, singing cheerful songs and flowing happily all day.

Environmental investigation report composition 400 words 13 When my father was young, it was a little difficult for my grandparents to earn very little every month, but they still had to support a family of six and their lives were not rich. I live in a low bungalow with chickens and ducks in the yard. When it rains, the yard smells good. At that time, dad didn't have toys and snacks, and friends often played clay figurines together. Every holiday, grandpa rides a bicycle with his father to visit relatives along the dirt road in the country.

Now, I am 12 years old. With the economic development of Hancunhe, great changes have taken place in our family. Mom and dad spent more than 2,000 yuan a month, which was dozens of times that of grandpa at that time. My family also moved into a spacious two-story villa. There are fresh fruits and vegetables and my favorite drinks in the refrigerator in the kitchen. Since then, I have my own bedroom with a writing desk, stationery and computer, which is convenient for me to access information online.

My father and I are much happier than I am, because the family income level has improved, so my childhood is very happy.

Environmental investigation report composition 400 words 14 This time, the teacher left a special assignment to investigate the environment in his hometown.

I went to the roadside of my hometown to investigate, and it looked like a garbage dump. A pile here, a pile there, dirty and smelly, which makes people smell disgusting.

It used to be clean and fresh, with flowers and trees, but now it has become a garbage dump. I really want to go back and see what it used to be like here.

Because people throw too much garbage and have no place to find it, all the garbage is spilled, causing serious car accidents and hurting people's lives.

There used to be a crystal clear river beside the road, but now it has been submerged by garbage.

Coupled with people's fire prevention, building houses and making all kinds of things, there is no one now. There is also a small bridge running on it. People often go there to play, play and take pictures, but now we can't see them.

Therefore, everyone should care for the environment and make the future world more beautiful!

On Saturday, my mother took me to Qilihe River next to our home.

When we came to Qilihe River, we saw a lot of rubbish in the river. I immediately asked my mother, "Why is there so much garbage here in Qilihe?" Mom said, "It's because some workers dumped the garbage from the car into the Qilihe River." I asked again, "Why is this water so smelly?" Mother said, "It's because these rubbish polluted the clear river, so the water stinks." At this time, only two or three small fish are swimming in the river. It seems to say, "our parents are dead, and we are the only ones left at home." I quickly asked my mother to give me a clean and beautiful fish tank, and then put these small fish in the fish tank and let them swim freely.

My mother and I immediately put all the rubbish on the ground into the trash can we brought, and we are cleaning up the sanitation here. Although my mother and I didn't clean up the Qili River, my mother and I put all the rubbish on the ground in the trash can, which is a token of our concern. We hope we have a beautiful nature!

We won't pollute the environment for those people again!

Environmental investigation report composition 400 words 16 On Sunday, my mother took me to the rice field to see what the rice field looked like. We will arrive soon.

We arrived, walked for a while, and a breeze blew and smelled a foul smell. I smelled it and didn't go far. I saw that all the creatures in the river were dead, and there was a lot of rubbish beside them. In the past, the river was crystal clear and small fish lived well. Why? I asked my mother, and my mother said, "Because many people don't care about the environment and litter, the air is polluted, the trees next to them are also polluted, and all the leaves are lost." We cleaned up the garbage, and when we got home, I made a sign that said don't litter. Littering will cause air pollution and trees will wither. We took the sign, walked over and put it there.

When we went back, we saw a man trying to make a fire, so we went over to him and said, "Don't make a fire, it will pollute the air. If the air is polluted, it will not be fresh. "

I did two good things today, and I am very happy. I will do good things every day.

On Saturday, my parents and I went to investigate, and went to Qilihe first.

My mother told me that it used to be a clear river, but people didn't care about it. They often threw rubbish and stones into it … that's why it has become so dirty now. I saw small fish struggling in the water and tadpoles swimming around in the water. They cried and said, "all our relatives were killed by those humans, and now only we are left." Seeing this scene, my tears almost stayed.

Look at the small garden next to our house, where the trees are lush, the flowers are in full bloom and the flowers are charming. Grass sprouted from the ground and birds sang softly on the branches. My father told me: "this place is very popular with people, and people often protect it." Sometimes, they water trees, flowers and grass to make the small garden more beautiful. "

After listening to my father's words, I don't think we should take care of the Qilihe River, but the small garden. We should give consideration to both and make our home more beautiful and brilliant.

On Saturday, my mother took me to grandma's house to see her. On the way, I saw a lot of rubbish in a small river. The river became dark and dirty, which made people sick. When I passed by here before, the river was crystal clear and even the small fish in it could be seen. Every time I pass by here, I feel very happy, but now I feel very sad when I come here, so I ask my mother, "Mom, why is this river so dirty?" Mother replied, "Because there are many factories by the river, all of which are smoking. These black smoke pollutes the river, and the garbage thrown by people is even more disgusting. " I also saw a few small fish scurrying about in the water, as if to say, "I don't want to live here anymore." My family was thrown away by garbage and black smoke. " Only when I heard these words from Xiaoyu did I know that Xiaoyu was really pitiful.

I asked my mother, "Mom, will this river be as clear as before?" Mother said: "Of course, as long as people care about the environment, this river will definitely change back to the original crystal clear one.

I must protect the environment and drive away more pollution in the future.

Environmental investigation report composition 400 words 19 Today I went down to observe the environment in my hometown.

The first thing I saw when I went down was the sky. Because there is smoke in the sky, it is foggy here. Because there are many factories in our family, I was thrown into the river not far away by human beings. Some of them are littered with rubbish, some are littered with waste plastic bags, some are littered with waste plastic bottles, some are smelly shoes, scrapped bicycles, useless books and so on. There are also some bad habits that have been polluted. In the past, the fish in the water were alive and kicking. Now that several small fish are dead, several small fish are struggling to get out. Finally, all the little fish died. The smoke in the factory also made my sister sick. It's a little serious. These trees were cut down by people, not by people. Some trees disappeared in the sky by smoke from factories, and grass disappeared in the air by smoke from factories. Now some good people are beginning to plant trees and flowers to keep green.

I want more flowers and trees to have more life in the future.

Environmental investigation report composition 400 words 20 Our community is a beautiful garden. There are tall buildings in it. There is a green lawn between the buildings. There are some flowers and trees around the lawn. Whenever I am in bloom, beautiful butterflies will dance among the flowers. I like this grassland very much and play here with my friends every weekend. One day we came to this meadow again and found some colorful plastic bags and some banana peels on the meadow. Our playfulness suddenly disappeared and we had to go home.

I can't sleep well every night, because there are many cats in our community, and they keep barking at midnight. The sound is like a child's crying, which makes me upset. Every weekend, our neighbors will play some songs so loudly that I have no intention of doing my homework. There is still a lot of pollution in our community. We often see some scraps of peel and paper thrown away by people on the road in the community, which pollutes the road. The exhaust gas from cars coming and going in the community pollutes the air again.

This is the environmental pollution in our community.

Before 2 1, our Zhaodong community was a beautiful community. The grass nodded happily to me, and the trees were like handfuls of green umbrellas, sheltering the people in the community and the flowers in the flower beds. It is colorful and beautiful. The buildings are arranged neatly, and the paths are interspersed among them.

However, because people litter now and don't pay attention to basic cleaning, she is not so beautiful. When I was investigating, I heard from the security uncle that there are more and more children in the community now. Every day after school, the students who return to the community begin to make a scene in heaven: some fight on the lawn; Some people beat holly with sticks; Holly was covered in scars. The empty water bottle turned into a Grenade ... suddenly the clean path was in chaos. Several puppies also came to join in the fun. They defecate everywhere, dirty and smelly, which seriously pollutes the environment.

People's behavior is destroying the environment of the community. So I want to call on people from all walks of life to do every little thing around them, protect nature and act together!
