Investigation report on environmental quality in Haikou city

final report

1. brief background: with the progress of society and the development of industry, people's quality of life is improving day by day, but people's awareness of environmental protection can't keep up with the pace of the times, and there is no progress at all, but it is declining day by day. The decline of resource reserves, the ravages of sandstorms, the shortage of water resources and the reduction of forest area have all satisfied people's growing desires in any case. Hainan's environmental quality is among the best in China, with fresh air and pleasant scenery. So, is that right? In this regard, we want to make a survey of Haikou, the capital of Hainan.

Purpose and significance: Through this environmental investigation, find out the loopholes and hidden dangers in environmental protection in Haikou City, so as to arouse people's attention and concern about the old problem of environmental protection and call on people to defend our beautiful island with practical actions.

3. Overview of activity steps:

(1) Check the environmental conditions in Hainan in recent years on the Internet.

(2) Take the method of sampling survey, and select several representative places for field investigation (such as parks, shopping malls, streets, villages, etc.). ).

⑶ Classify, analyze and summarize the collected data (with photos), and get the feeling of this activity.

4. Investigation methods: online inquiry, on-the-spot investigation and relying on life experience.

5. Contents:

1. The forest area has decreased sharply.

Hainan is a tropical island and one of the most important tourism projects in our province. There is only a tropical rain forest in Hainan Island in China, but its proportion in the total land area has dropped from 0.25 at the beginning of the province to less than 0.02 at present. As follows: At the beginning of the province, the area of tropical rain forest occupied about 8500KM of the whole country.

At present, the area of tropical rain forest in our province accounts for 0.0 189, which is about 542.6KM.

The primary forest coverage rate dropped from 0.35 in 1950 to 0.072 in 1987, and now it is only about 0.04. As follows:

1950 The original forest coverage rate is about 1 1900KM.

1987, the original forest coverage rate is 0.072, about 2448KM.

At present, the coverage rate of virgin forest in our province is 0.04, which is about 1360KM.

2. Industrial pollution in Hainan

An important reason why Hainan attracts tourists is that the air is clean and pollution-free, and the air quality is worrying, which directly affects the development of tourism in Hainan. According to the environmental quality bulletin of our province from 65438 to 0998, the dust output of the cement plant in that year was 33,000 tons, and acid rain also fell in Haikou, Danzhou and Sanya. In this year, of the 930,000 tons of municipal solid waste in the province, only 0.724 ton was basically treated, and the rest were randomly piled up, among which plastic waste was polluted everywhere. In the investigation, the author found that there are large-scale brick burning operations in Xiuying-Shishan section of Haiyu Middle Line and Yongfa Town-Xinxu Town section of Chengmai County. Black smoke drifted with the wind. Compared with 1997, the noise pollution in Haikou City increased by 0.4 dB. The noise pollution in Sanya has increased by 2 decibels. In recent years, dead fish have appeared in Lingshui and Wanning. Last year, crude oil leaked from Haikou and polluted the sea surface. Recently, there has been a red tide in Haikou.

3. Air quality in Haikou

According to the report of the Municipal Bureau of Land, Environment and Resources, in 2006, Haikou's air quality was superior to the national first-class standard and continued to maintain the national first-class level. In 2006, the air quality 1 day was 300 days, and in 2005, it was 29 1 day, and the first-class days were improved. Although the relevant statistical results of the State Environmental Protection Administration have not been finally announced, people in the industry said that in the first three quarters of 2006, the average number of days with excellent air quality in11three key cities nationwide was 84%, of which only eight cities, including Haikou and Beihai, had excellent air quality, and Haikou became one of the few key cities with excellent air quality in China in 2006.

In order to reduce the pressure of air pollution, the city has designated areas where burning highly polluting fuels is prohibited. At present, more than 200 industrial enterprises above designated size in the city have basically completed the transformation from oil-fired boilers to gas-fired boilers. At the beginning of 2006, the urban gasification rate reached 97%. Haikou's annual industrial coal consumption is less than 30,000 tons. No wonder tourists praise Haikou as a "smoke-free city" and "Haikou's air can be canned for export".

However, there are still many enterprises with serious pollution in Haikou, which is undeniable. Some companies even produce products that are harmful to the ozone layer. People usually don't pay attention to the environment, and they also emit substances harmful to the air in their lives, which poses a threat to the environmental quality of Haikou. Therefore, while we are happy, we should also clearly recognize the shortcomings and improve the improvement measures.

4. Haikou water resources

Haikou: a city with seasonal water shortage

Regarding the water resources in Haikou, a survey conducted by the Municipal Water Conservation Office shows that Haikou is a tropical coastal city with seasonal water shortage. Haikou's water resources mainly come from surface runoff generated by rainfall, with the average annual rainfall of 18 16 mm and the total self-produced water resources of190.7 billion cubic meters. The total water resources are equivalent to the depth of surface runoff of 830 mm, the annual average temperature of 23.8℃ and the annual average evaporation of19/kloc-0. According to the population at the end of 2003, the city's per capita water resources are only 1 190 cubic meters, which is close to the international serious water shortage standard of per capita water resources 1000 cubic meters. It is a rare tropical coastal water shortage city.

Find out your family background so that you can manage your family well. In view of the serious shortage of water resources in Haikou City, in order to ensure the sustained, healthy, rapid and coordinated development of Haikou's economy and society, since the 1990s, Haikou City has put forward the water-saving goal of "building Haikou into a water-saving coastal city" in 1994.

on-the-spot investigation

During the investigation, our team members found that the water resources in many places in Haikou were seriously polluted.

East Lake: East Lake is located in the prosperous area of Haikou. It is said that the water quality of East Lake used to be very clear. What I see in front of me is beyond recognition. East Lake

The lake stinks, and some plastic bag pollutants are floating on the lake. I think anyone who walks by the lake will smell this.

A bad smell will make people lose their elegance.

Hongcheng Lake: Speaking of Hongcheng Lake, I think many Haikou people are familiar with it. The Red City Lake in the past is not what we see today. current

Hongcheng Lake is like a stinking ditch in our eyes. It smells disgusting and there are still dead fish floating in the lake.

There is a lot of rubbish, which seems to have become a dump. Some small business stalls on the shore also discharged sewage into the lake, which further aggravated the Red City.

The deterioration of lake water quality.

……

There are places like Longkun Gully and Xiuying Gully. I think in the eyes of Haikou citizens, such a place is not uncommon, but it has never attracted people's attention. Can environmental protection only be solved by the government? Can we really turn a blind eye to this situation? In our daily life, not only water resources are polluted, but also water resources are wasted more frequently.

At school, you can often see that the faucet is not tightened.

(2) Sometimes at home, in a hurry, just leave. I don't care if the tap is still there.

③ The water used for vegetable washing is often dumped at will, and secondary water use is not realized.

In some places, the water pipes are broken. Anyway, if they are not repaired in time, the water will flow away in vain.

……

Do you really have to wait until there is a serious shortage of water resources to know the value of water resources? Don't you know what's left after the sweat drops?

suggestion

(1) The public should raise their awareness of environmental protection, and garbage should be thrown into the trash can.

(2) The government should strengthen environmental protection, improve public health facilities and increase publicity.

③ Middle school students can use their spare time to publicize the importance of environmental protection in the streets and set an example.

Enterprises should not only pay attention to personal interests, but also take a long-term view and put the environment first.

⑤ Reuse the waste water, and don't waste it at will.

feeling

Through the completion of this research study, I have the following feelings:

1. Whatever you do, you should cultivate your hands-on ability. Although the process is hard, the result is happy.

Everyone has an unshirkable responsibility for environmental protection. Don't always take chances.

Things always have two sides. We should realize that we can't be carried away by the good side, and we can't understand things better and more comprehensively.

As long as we are United, we are not afraid of any difficulties.

When cooperating with others, we should not only consider ourselves, but also the team members.

This is our first attempt. Although it is not satisfactory, after all, we have worked hard and gained a lot of experience. I think we will do better next time.

-gu

Taking part in this research, I feel a lot. On the whole, Haikou's environmental sanitation has shown a good development trend, and the construction of new countryside has also made gratifying achievements. The investigation process is far more difficult than expected, not only to find information on the internet, but also to conduct on-the-spot investigation, but at the same time I also learned a lot. Investigation is not an easy task, and it needs constant efforts. Isn't it the same in ordinary life?

-Zhan Jingjing

From this survey, it can be seen that government departments have indeed made some efforts in adding garbage bins and distributing cleaning for environmental protection in various places ... but this is only superficial treatment and cannot fundamentally solve the problem. On this issue, people are generally divided into three types: the first is to adhere to environmental protection and care for the environment all the time, and such people account for a minority in the total number of people in our city; The second is to go with the flow. When the surrounding environment is beautiful, it is naturally unbearable to destroy it. However, in a messy environment, because "it's dirty, even if I throw garbage, others won't say it", so when there is garbage in my hand, I usually throw it on the ground at will. At present, such people account for the majority of the total number of people in our city; The third is convenience first. No matter where they are, such people will throw away their own garbage for their own convenience. Such people account for a small part of the total population in our city. In this case, surface treatment is obviously an inefficient and incomplete method. To solve environmental protection problems efficiently and comprehensively, we should start with citizens' thoughts and education, let them know the importance and necessity of protecting the environment, and make people's awareness of protection not "adapt to local conditions". Although it is difficult, I believe that as long as we make unremitting efforts, we will succeed!
