The Significance of Arbor Day Activities

The significance of Arbor Day activities 1 What is a green life? What is the significance of Arbor Day activities? In spring, everything revives, which is the golden season for all kinds of trees. A variety of trees can not only beautify the environment, improve air quality, but also improve climate conditions, killing two birds with one stone.

Dense canopy can block sunlight, reflect about 20% heat back to the sky, and 60%-70% heat is absorbed by canopy. In addition, the maintenance of plant transpiration also needs to absorb a lot of heat. Because of the high air humidity, large heat capacity and small wind force in the forest, the temperature changes slowly.

It is observed that the temperature in forest areas is 8-9℃ lower than that in non-forest areas in summer, but 2-3℃ higher in winter, which is really "warm in winter and cool in summer". In addition, forests can also regulate air humidity. The regulation of air by forest is accomplished through the constant transpiration of tree crown. In the dry season, the huge roots of trees absorb a lot of water in the soil and transport it to the atmosphere through leaves, which increases the humidity of the air, thus alleviating the degree of drought. According to the measurement, the relative humidity in forest areas is 30%-40% higher than that in non-forest areas in summer and 10% higher in winter.

Forest is not only an air conditioner of nature, but also a humidifier, which contributes a lot to improving air quality. When the forest coverage rate reaches more than 35%, a climate suitable for human life can be produced. According to scientists' estimation, in summer, every hectare of poplar transpiration 57 tons of water every day, consuming 654.38+0.8 megajoules of heat; Each hectare of broad-leaved forest absorbs 575 tons of groundwater from the soil a year, and consumes heat 1.25 mj. Its transpiration is 50% more than that of the ocean at the same latitude and 20 times that of the forest-free area. Besides, the forest is a paradise for nature. After the wind meets the forest, part of the airflow crosses the sky, part of the airflow is blocked by trees, and the wind drops sharply. When it reaches the forest area 200 meters, the wind speed is generally only about 5% of the original, thus greatly reducing the wind disaster.

Voluntary tree planting by the whole people is a great cause for the benefit of the people. Over the years, the vigorous development of voluntary tree planting activities has played an important role in raising the awareness of greening of the whole people, speeding up the construction of green land and ecological environment, and promoting economic development and social civilization and progress.

Planting trees is a good thing to create a good ecological environment and benefit future generations. Participating in tree planting is not only an obligation, but also a responsibility. The whole society should take active actions to plant trees and green our homes, so that the land we live in is greener and more beautiful.

The Significance of Arbor Day Activities Chapter II After the founding of New China, in order to commemorate the revolutionary pioneer, the Gregorian calendar date of Sun Yat-sen's death, 12 March, was designated as Arbor Day.

The Chinese nation has a glorious tradition of planting a variety of trees since ancient times. Bai Juyi, a great poet in the Tang Dynasty, was a local official. Wherever he goes, he plants flowers and trees, which is also reflected in his poem: "Plant two pine trees with your own hands and talk about them as guests"; "White-headed plants and pine laurels will see the forest sooner or later." When Su Shi was appointed as the secretariat of Hangzhou, he built the West Lake and planted trees on the lake embankment, leaving a famous landscape of "Xiao Chun, Su Causeway". Liu Zongyuan was demoted to Liuzhou, but he still did not forget to plant trees: "Liuzhou secretariat, planting willow river"; "200 citrus trees were planted by hand, and new leaves spread all over the city in spring." At the end of the Qing Dynasty, Zuo led the counter-insurgency movement in Xinjiang and planted willows along the way, which was called Zuo in history. His assistant, Yang Changjun, sang in the poem: "Newly planted willows are three thousand miles away, leading the spring breeze through Yumen Pass."

In our country, almost all places of interest have the shadow left by their ancestors. In the Mausoleum of Huangdi, it is said that the cypress trees planted by Huangdi himself (called "Huangdi cypress") are lush and nostalgic; In the ancient city of Qufu, there is Confucius' "hand-planted cypress". There is also a "cypress planting by Emperor Wu of the Han Dynasty" in Dai Temple on Mount Tai. These thousand-year-old trees have now become key protected cultural relics. "There are many people reading trees in the atrium", and the descendants of the Chinese people will naturally have reverence for "the predecessors planted trees and the descendants enjoyed the cool".

The ancients not only attached importance to planting trees, but also attached great importance to protecting trees. As early as the Xia Dynasty, China had administrative regulations to protect forests. "Yizhoushu" records: "Danger is forbidden, and there is no axe in spring and March, so it will become a plant." During the Spring and Autumn Period and the Warring States Period, Guan Zhong once said: "It is a crime to cut mulberry dates for wage earners without protecting their forests, not being the king of the world ..." Song Taizu Zhao Kuangyin stipulated: "It is a crime for people to cut mulberry dates for wage earners." When Yongzheng ascended the throne in the Qing Dynasty, he demanded strict protection of the mountain forest: "It is forbidden to trample on cattle and sheep and steal gangsters."

Feng Yuxiang, a famous patriotic general in modern times, also loves trees very much. When he led troops to fight, he stipulated that the officers and men of the garrison should plant all kinds of trees in the station, and even when marching, they were not allowed to trample on trees. When he was stationed in Xuzhou, he wrote a forest protection poem specifically for strict discipline: "Lao Feng was stationed in Xuzhou, and the trees were green. Whoever cuts down my tree, I will cut off his head. "

Among the people, there are also many stories about protecting trees. Legend has it that there is a Gu Song in Jingci Temple, West Lake, and the new magistrate ordered an expedition to build a yamen. The abbot is at the end of his wit. Fortunately, a Buddhist monk in Jidian wrote a poem for the prefect. The poem reads: "The court is a hundred feet high and has been friends with monks for a long time. It is said that the leaves are flourishing for thousands of years, and knives and axes are thrown together. There is no shadow of dragons and snakes in front of the court, and there is no wind and rain on the side of the house. The hardest thing is to fly cranes in the morning and not see the old nest at night. " The satrap read the poem, weighed the interests and finally took it back.

Significance of Arbor Day Activities 12 March 3rd is the annual Arbor Day. This is a festival for people all over the world. On this day, no matter who can take part in tree planting, whether the tree is transplanted or planted, whether it is planted successfully or not, it always represents our recognition of tree planting activities and our attention to tree planting.

But what are the benefits of planting trees?

Planting trees is certainly beneficial, but also has a wide range of influence and practical significance.

According to the information on the website, afforestation can reduce noise. Noise below 50 decibels does not have much impact on people, but when the noise reaches 70 decibels, it will cause obvious harm to people. If the noise exceeds 90 decibels, people can't work for a long time. At present, the noise in many cities in China exceeds 70 decibels, and afforestation can reduce the noise. For example, when we walk in a park surrounded by trees, we will feel very quiet around us.

In addition, afforestation also plays a role in preventing wind and fixing sand, controlling climate, reducing soil erosion and maintaining ecological balance. Take the simplest example: in winter, northwest wind prevails in inland areas of China, that is to say, in the case of uneven distribution of cold and hot air, air always flows from places with high air pressure to places with low air pressure, thus forming wind. In winter, the inland of Asia is hot and dry, and the air pressure is high, so in China, the wind always flows from the northwest inland to the southeast coast. We all know that there are many deserts in Inner Mongolia, so the wind blowing from the northwest carries a lot of sediment. However, if rows of trees are used as protective belts in the northwest of many cities, the sediment in the wind can be reduced and the wind can also be reduced. With the passage of time, the urban environment can be improved and controlled.

In addition, trees are also automatic thermostats for bacteria, natural dust collectors, oxygen plants and disinfection stations. In summer, the cool place is much lower than the outdoor temperature, so it can escape the heat, but it is a little higher than the outdoor temperature in winter. There are many tiny hairs and mucus on the leaves, which can absorb harmful particles such as carbon and sulfide in smoke and dust, as well as harmful substances such as germs and viruses. The leaves of green plants can also absorb carbon dioxide and release oxygen through photosynthesis.

It can be seen that planting trees does have amazing benefits, so it can be advocated all the time in the world. You can even make an activity an annual festival, which can also reflect the importance attached to tree planting around the world.

Then, since planting trees has such a great role, we should also take action and join the ranks of planting trees together.

It happens that today is Sunday. I specially brought my parents, prepared buckets, hemp ropes, three towels and three bottles of mineral water, and carefully screened more than a dozen saplings next to grandpa's vegetable garden. I tried my best to find a road under construction, next to residential buildings, full of dust and yellow sand, and trees were planted on both sides of the road.

Dad didn't run far and found a sewer without a cover. Although the water inside is turbid and there are impurities floating, it is more than enough to plant trees.

Dad is responsible for transporting water, I am responsible for digging holes and planting seedlings, and my mother is responsible for watering. Finally, we will straighten the tree and stamp the soil together. The whole process of planting trees took about two and a half hours, and we were all very tired. It's just that a bottle of mineral water is not enough for one person, and a towel for one person can't wipe off our sweat.

The process seems simple and easy, but it is not. After we plant the tree, we can't laugh even if we want to be happy. It is conceivable that the treatment is not ordinary!

Although planting trees is a very difficult and headache thing, I believe our family must be very happy and satisfied because we have gained practice and experienced things that ordinary people can't understand. On the contrary, I think planting trees is a gift from God.

Talking about the significance of planting trees and practicing tree planting in the early days of Arbor Day is nothing more than hoping that everyone can clarify the significance of Arbor Day and tree planting activities, so that more people can participate in the ranks of tree planting and contribute their own strength, so that they can take a small step forward in their life journey and take a big step for social growth and moral practice.

The Significance of Arbor Day Activities 4 The annual March 12 is here again. It's the day when spring blooms, and it's also the Arbor Day stipulated by our country. In response to the call of the state to beautify and green the environment. It is decided that the whole school will have a day off, so that our classmates can freely combine to carry out tree planting activities.

As soon as I heard this, I was so happy that I immediately winked at my good friend Lu and asked us to plant trees together. Where to plant trees? We discussed it and finally decided to plant it in the square. Why did you plant it there? Because some time ago, I went to the square to play in the morning. I had a good time at first, and so did my grandparents who went there for morning exercises. But soon, the sun rose slowly and the temperature soared, which made us uncomfortable. I quickly want to find a place to hide. There are no trees in such a big square, so I can't help it. Although I didn't have a good time, I had to go home reluctantly. When I left, I saw that there were only a few people left in the bustling square. It seems that everyone is scared away by the hot sun like me. So I think it is more meaningful to plant trees there. I believe that in the near future, when the trees we plant grow up, everyone can enjoy the cool in our trees in hot summer.

After we decided on the place, we took action immediately, took out pocket money, asked for some saplings in the flower shop and asked my father to help me send them to the square. We will start work as soon as we find a good place in the square. First, let's dig a hole together. After digging the pit, one of us helped to raise seedlings, and one of us lived in the pit to cultivate the soil. Don't look at the action of cultivating soil in the pit. It's simple and really difficult. Soon our heads and faces were sweating, and sweat kept running down our backs. Finally, my hands were tired, but we encouraged each other and finally insisted on planting all the saplings we bought.

Finally, we water the saplings. Looking at the straight saplings, we seem to see them grow up day by day, and the dense shade is full of people enjoying the cool.

This is really a meaningful Arbor Day.

The Significance of Arbor Day Activities On March 12, my long-awaited Arbor Day finally arrived. In the morning, the weather is sunny, sunny and breezy. There are white clouds floating in the blue sky, some like little sheep grazing on the grassland, some like ships sailing in the sea, and some like running deer. We sang and laughed all the way, and waves of sweet children's voices rushed through the window and flew to the fields. Planting trees in the botanical garden is our common dream.

We came to the botanical garden excitedly and looked up. Wow! Red flags are fluttering on the hillside, and there are so many people! I saw groups of people digging, filling and watering. Everyone is in full swing.

Not willing to lose our way, we quickly chose a good battlefield for afforestation. Some hold hoes to dig tree pits; Some shovel dirt; Some move saplings; Others took buckets to fetch water from the river. Everyone seems to have inexhaustible energy. Look! How hard Sun Xinyue in our class works! I saw her feet slightly open, posing as an "eight", holding the sapling tightly in both hands, for fear that the sapling would fall. Yan Shuxin, hunched over, with a small shovel in her hand, is cultivating the seedlings tree by tree! After filling and filling, the soil in the tree pit is full, and the saplings have stood firmly. Sun Xinyue let go of her hand, and she and I pressed the soil tightly with our feet, and then slowly poured water into the soil, and the water slowly seeped in. The sapling "drank" enough water and nodded again and again, as if to say, "Thank you for your cultivation. I will grow into a towering tree and let you enjoy reading and playing in my shade."

Everyone is busy. It's almost noon, and the trees are almost planted. We watched the saplings we planted swaying in the breeze, and there was an indescribable joy in our hearts. Everyone can't help but say, "It will grow into a towering tree in a few decades." "I want to see it every spring." I named it "Happiness Tree" ... After the tree was planted, I took out a "wish card" that I had already prepared from my pocket and tied it to the branch with a red ribbon. I made a wish in my heart: May Xiao Shu grow up with us and become a pillar of the country!

This meaningful activity not only relaxed our mood, but also brought us closer to nature, adding a greenery to our hometown. This activity really makes me happy!

The Significance of Arbor Day Activities Chapter VI The purpose of Arbor Day activities is to stimulate people's feelings of loving forests and afforestation, improve people's understanding of forest functions, promote land greening, and achieve the purpose of loving forests and protecting forests, expanding forest resources and improving the ecological environment. It is a prescribed festival activity to mobilize the whole people to plant trees!

Arbor Day activities are also of great practical significance. The significance of Arbor Day activities is not that everyone should plant a tree on Arbor Day, but that through the coming of Arbor Day again, all of us will pay more attention to greening and environmental protection issues and take better actions.

First of all, forests can balance the carbon dioxide of the earth. Forests are the main consumers of carbon dioxide. Every hectare of forest produces 10 tons of dry matter, which will absorb 16 tons of carbon dioxide and release 12 tons of oxygen, making the forest a huge oxygen storage. So afforestation has become the main way to slow down the greenhouse effect.

Second, forests can prevent wind and fix sand. Forests can reduce wind erosion intensity by reducing wind speed and changing wind direction; The strong roots of trees, especially shrubs, can fix soil particles. Practice has proved that building windbreaks, combined with agricultural and water conservancy measures, can achieve good windbreak and sand fixation effects.

Third, forests can keep water and soil. Forests can regulate runoff and water quantity in dry season, maintain soil and water, reduce sediment content in rivers and alleviate floods. The observation shows that the litter layer with the thickness of 1 cm can reduce the surface runoff to 1/4 of the bare land, and the sediment amount can be reduced by 94%. The bare soil loss caused by rainfall is more than 1000 times that of forest land, but the soil consolidation ability of the combination of trees, shrubs and grass is more than1000 times that of pure grass. It is estimated that China's forests reduce the total soil erosion by 24.6 billion cubic meters every year, reduce the soil organic matter loss by 384 million tons, and the soil protection value reaches more than 260 billion yuan. In addition, forests have a fundamental mitigation effect on preventing riverbed rise, floods and droughts.

Fourth, forests can conserve water. Forest is a natural "green reservoir", which can promote the normal circulation of sky water, surface water and groundwater. When it rains, more than 20% of the rainfall is intercepted by tree crowns and branches and leaves, and 5% ~ 10% is intercepted and absorbed by ground leaves and weeds. Soil with granular structure in forest can quickly convert surface water into groundwater. According to incomplete estimates, the annual water conservation capacity of forests in China is 347.3 billion tons, equivalent to 75% of the total storage capacity, and the annual water conservation value is more than 250 billion yuan.

Fifth, forests can protect biodiversity. Forest is the "home of species" and the biggest treasure house of biodiversity and biological gene resources. More than 50% species in the world inhabit various forests, mainly natural forests.
