Common sense of protecting Erhai Lake environment

1. After listening to the lecture on protecting Erhai Lake, write a composition

Protecting Mother Lake-Erhai Lake

Erhai Lake is the mother lake of the Bai people in Dali. It is located at the eastern foot of Cangshan Mountain in the west of Yunnan Province, and eighteen streams of Cangshan Mountain enter the lake in the west, with a lake area of about 246 square kilometers. Because its lake is shaped like an ear and its waves are as big as the sea, it is called Erhai Lake.

In the past, Erhai Lake was like a beautiful fairy: during the day, a green tree in the distance swayed gently with the refreshing breeze by the lake; The dark green lake nearby reflects the blue sky and white clouds like a jade; Leaf by leaf canoe crossed the quiet lake, rippling a string of tiny ripples, just like flowers blooming on the lake ... At night, Erhai Lake is a mysterious reverie. The bright moon is in the sky, and the bright moonlight falls on Erhai Lake, which is like a bright veil in a cage ... But now Erhai Lake has changed a lot.

Erhai Lake is no longer as glittering and translucent as a piece of jade, but also because its descendants-human beings seem to forget the existence of this mother, and constantly discharge industrial wastewater and domestic garbage into its body, making it increasingly gaunt; Now the ripples on Erhai Lake are no longer like blooming flowers, because people are rowing not to enjoy the scenery, but to listen to their mothers' cries, and those ripples are like a drop of their mother's sad tears; Now Erhai Lake is no longer a mysterious reverie, because it is turbid and no longer reflects the bright moon ...

Erhai Lake mother finally couldn't stand it and got angry. It broke the tenderness of the past and rolled up a heinous wave on the lake. Those who are catching its pet-fish are all involved in the whirlpool of Erhai Lake, and everyone is aware of the seriousness.

descendants of Erhai Lake! Is it so difficult for us to protect our mother Erhai Lake? When we protect Erhai's mother, Erhai's mother will also give us a sweet smile. Why not? If we all listen carefully, we will hear Erhai's mother crying softly. She is eager for her children and grandchildren to care about her and take care of her, so as not to destroy her beautiful face and gorgeous clothes. People often say: "Erhai Lake is clear and Dali is prosperous." Everyone should know that we are actually protecting ourselves by protecting Erhai Lake.

2. How to write a handwritten newspaper to protect Erhai Lake

2. Promote Erhai Lake protection concept, advocate green life, fulfill Erhai Lake protection responsibilities, and build a beautiful home. 3. If human beings don't save water and protect the environment from now on, the last drop of water they see will be their own tears.

4. Erhai Lake is clean, Dali is prosperous, protecting Erhai Lake and caring for the environment are our responsibilities and obligations. 5. Erhai Lake is our "Mother Lake" and the foundation for Dali's survival and development.

6. Dumping, piling up garbage and wastes, and building toilets and garbage pools are prohibited in Erhai Beach and its management area. 7. The ban on fishing in Erhai Lake is beneficial to the present and the future.

8. Let's work together to protect Mother Lake, the pearl of the plateau. 9. Protecting Erhai Lake and protecting the ecological environment is an important way to realize the harmonious development between man and nature.

1. Seriously implement the Regulations on the Management of Erhai Lake in Dali Bai Autonomous Prefecture. It is forbidden to dump sewage, domestic garbage, scraps of paper and cigarette butts into Erhai Lake. 11. Protect Erhai Lake, protect the environment and realize the coordinated development of resources, ecology, economy and society.

The rippling Erhai Lake reappears. The wetland of the West Lake in Eryuan County, which is connected with Erhai Lake, becomes the filter of Erhai Lake, and the blue sky and white clouds set off the "Erhai Lake Defence War". The quiet Erhai Lake nestles in the arms of Cangshan Mountain. The sunshine in early winter is scattered on the breezy lake, and the clean and transparent water body can be seen three or four meters deep at a glance.

Wild ducks swim in the lake, egrets float, and pieces of fishing boats can be seen in the distance ... boating on Erhai Lake, a poetic feeling of "the boat is floating in the blue waves and people are in Traveling in a pictorial world" arises spontaneously. Looking at the beautiful scenery in front of us, people who have just arrived in Erhai Lake will never think that Erhai Lake, which was once invaded by cyanobacteria, was "white in the wind and washed away in the rain".

since 198s, with the rapid development of agriculture in the river basin, phosphorus, nitrogen and other fertilizers were widely used, and the process of industrialization and urbanization in the surrounding areas was rapidly promoted, all kinds of domestic and industrial sewage and garbage could not be treated in time and effectively, which caused a series of ecological and environmental problems. In, blue-green algae broke out in Erhai Lake, and the transparency of the lake suddenly dropped from 4 meters to .5 meters.

In, blue-green algae broke out again on a large scale in Erhai Lake, and the water quality dropped to Class IV. Two blue-green algae blooms in Erhai Lake aroused the deep worries and thoughts of the children of all ethnic groups in Dali.

A "Erhai Lake Defence War" of "protecting Mother Lake like protecting eyes" began. Through the comprehensive management of "following the law naturally, scientific planning, comprehensive source control, administrative accountability and national participation", the water quality of Erhai Lake has been obviously improved.

"Since, the water quality of Erhai Lake has been continuously improved for five consecutive years, and generally maintained at Grade III, and reached Grade II in March and April, and the natural ecological environment of the basin has been gradually improved." Li Qiongjie, director of the Environmental Protection Bureau of Dali Bai Autonomous Prefecture, said.

In early December, the Ministry of Environmental Protection held an exchange meeting on Erhai Lake protection experience in Dali, and Erhai Lake was praised as one of the best protected lakes in the suburbs of the city. At the 13th World Lakes Conference held this year, the protection and governance model of Erhai Lake was highly praised by experts and scholars attending the conference, and it was considered that the success of the protection and governance of Erhai Lake provided experience for the protection and governance of lakes in China.

Reduce pollution load and build an ecological wetland of "one river and two rivers". On December 9, the reporter came to the wetland at the mouth of Luoshi River in Shapingwan, Shangguan Town, Dali. A beautiful ecological wetland landscape was presented: cobblestone paved paths, wooden viewing platforms, tall trees and green grass on the shore, and all kinds of aquatic plants in the wetland complement each other ... "A few years ago, it was a weedy estuary in the lower part of Luoshi River, which was dirty and dirty. A lot of manpower and material resources have been invested to restore and rebuild here.

Now, the water is clear, the scenery is beautiful, there are more tourists coming, and our life is getting better and better. " Du Zikai, a villager from Xizhawei Village, Shaping Town, Shangguan Town, said.

"Luoshijiang is one of the important recharge sources of Erhai Lake, accounting for 13% of the incoming water of Erhai Lake. Due to the concentration of villages in the basin, the large population and the prominent non-point source pollution, the water quality of Luoshi River reached Grade V at the worst, which seriously affected the water quality of Erhai Lake. "

Yang Hongyuan, deputy mayor of Shangguan Town, said that in order to protect the ecological environment of Erhai Lake, Dali invested 1, yuan to restore and rebuild the wetland at the mouth of Luoshi River entering the lake, and so far it has invested 1, yuan. The restoration and reconstruction of wetland has played a good role in intercepting the nitrogen and phosphorus carried by the runoff of Luoshi River and reducing the pollution load of Erhai Lake.

The reporter learned that, in view of the current situation that "one river and two rivers" (Luoshi River, Miju River and Yong 'an River) in the north of Erhai Lake account for 7% of the water inflow and 65% of the pollution load, Dali has started to implement the construction of "one river and two rivers" ecological wetland, and plans to invest 27 million yuan to plan and construct an ecological wetland mu in the "one river and two rivers" basin. At the same time, it will speed up the construction of environmental protection infrastructure, invest 1, yuan to build sewage collection and treatment plants in Xizhou, Shuanglang, Shangguan, Zhoucheng and other market towns, and carry out the construction of small incineration facilities and farmers' sewage collection and treatment facilities.

In addition, we will speed up the adjustment of agricultural industrial structure and the development of eco-wetland tourism, and take a civilized development road of production development, affluent life and good ecology. Reduce non-point source pollution and develop ecological farming and aquaculture. The lake is like jade, and the white houses with white walls and gray bricks are surrounded by mountains and waters. In the fields on both sides of the road, green broad bean seedlings are lush ... From thousands of miles of ice, I came to Eryuan County, Dali Bai Autonomous Prefecture, and I was full of beautiful rural scenery.

Eryuan, named after Erhai Lake originated here, has seven rivers, including Mimao River, flowing into Erhai Lake, and five lakes, such as Haixi Lake and Zibi Lake, with a runoff of 7 million cubic meters. "The water management of Eryuan is directly related to the success or failure of Erhai Lake protection."

Ma Lisheng, deputy head of Eryuan County, said. Eryuan County is a typical agricultural county with more than 43, mu of cultivated land.

Ma Lisheng said: "Garlic is a special vegetable in Eryuan, which has good economic benefits, but it also uses a lot of chemical fertilizers, and a large amount of chemical fertilizers are lost into Erhai, resulting in serious agricultural non-point source pollution." In order to protect Erhai Lake, Eryuan County actively guides farmers to adjust their planting structure, reduce kind of garlic and diversify broad beans.

in order to reduce the use of chemical fertilizers, Eryuan county mainly focuses on Dengchuan town and Yousuo town, and carries out soil testing and balanced fertilization, reducing the use of nitrogen and phosphorus chemical fertilizers by more than 15% per mu, and promoting slow-release fertilizers on rice, garlic and other crops. Eryuan county also promotes the use of organic fertilizer in agricultural production and develops ecology.

3. 1 tips for environmental protection

1. It is proud to save water-turn off the tap at any time and don't let the water run empty. China is one of the 12 water-poor countries in the world, and its fresh water resources are less than a quarter of the world's per capita water.

more than half of the more than 6 cities in China are short of water, of which 18 cities are seriously short of water. The scarcity of surface water resources leads to excessive exploitation of groundwater.

in the 195s, water could be pumped from wells in Beijing about 5 meters below the surface. Now, the average depth of 4, wells in Beijing is 49 meters, and the groundwater resources are almost exhausted. 2. Guarding the water source-protecting the water source means protecting life. According to environmental monitoring, about 1 million tons of sewage is directly discharged into water bodies every day in the country.

more than half of the seven major river systems in China are polluted. Of the 35 key lakes, 17 are seriously polluted, and one-third of the country's water bodies are not suitable for irrigation.

more than 9% of urban waters are seriously polluted, more than 5% of urban water sources do not meet drinking water standards, 4% of water sources are no longer drinkable, and 6%-7% of the total water shortage in southern cities is caused by water pollution. 3. Multi-use of one water-reuse of water 7% of the earth's surface is covered with water, with about 1.4 billion cubic meters of water, of which 96.5% is seawater.

Although the rest is fresh water, more than half of it is directly available water resources such as ice, rivers and lakes, accounting for only about .3% of the total water. 4. Stop dripping-check and repair the faucet. 5. Use detergent carefully-use soap as much as possible to reduce water pollution. Most detergents are chemical products, and a large amount of wastewater with high detergent content will be discharged into rivers, which will worsen the water quality.

Long-term improper use of cleaning agents will damage people's central system, hinder people's intellectual development, reduce their thinking ability and analytical ability, and even cause mental disorders. If the detergent remains on clothes, it will cause allergic dermatitis to the skin. If the detergent with high concentration is used for a long time, carcinogens in the detergent will enter the human body from the skin and mouth, which will be harmful to health.

6. Care about the air quality-don't forget that you are breathing all the time. The monitoring results of the Global Atmospheric Monitoring Network show that the daily average concentration of total suspended particles in the atmosphere of Beijing, Shenyang, Xi 'an, Shanghai and Guangzhou is 2-5 micrograms per cubic meter, which is 3-9 times higher than the standard of the World Health Organization and is listed among the top ten polluted cities in the world. 7. Turn off the lights-save electricity, and one less pollution will pollute our country, which is dominated by thermal power generation and coal as the main energy source.

coal accounts for more than 7% of the disposable energy structure. If it is developed in the conventional way, to reach the level of developed countries, at least 1 billion tons of coal will be needed for energy consumption, which will be equivalent to the sum of global energy consumption. When coal is burned, it will release a lot of harmful gases, seriously pollute the atmosphere, form acid rain and cause greenhouse effect.

8. Save electrical appliances-A lot of coal, natural gas and petroleum fuels are used in industry, commerce, housing and transportation to slow down the global warming. The excessive carbon dioxide produced when these fuels are burned is like a glass cover, which blocks the ground heat from radiating to outer space and keeps the hot gas in the atmosphere, resulting in the "greenhouse effect", which makes the global meteorological variation, produces disastrous droughts and floods, and melts the icebergs in the North and South poles, leading to the rise of sea level.

Scientists estimate that if the trend of climate warming continues, low-lying deltas in Bengal, Holland, Egypt, China and some island countries will be in danger of being swallowed up by seawater. 9. Reduce the use of air conditioners-reduce energy consumption. When fuels such as coal are burned, oxides of carbon and nitrogen are emitted in the form of gases. These oxides combine with water vapor in the air to form highly corrosive sulfuric acid and nitric acid, which fall back to the ground together with rain, snow and fog. This is the acid rain called "death in the air".

There are three major acid rain areas in the world: the United States and Canada, northern Europe and southern China. Acid rain can not only strongly corrode buildings, but also acidify soil, resulting in trees dying, crop yield reduction, lake water becoming sour, and fish and shrimp dying.

Because of the extensive use of coal fuel in China, the annual economic loss caused by acid rain pollution is about 2 billion yuan. The acidity of precipitation in acid rain areas in China is still rising and the area is still expanding.

1. support green lighting-everyone uses energy-saving lamps "China green lighting project" is one of the key points of energy conservation in China. According to the implementation plan of the project, energy-saving and high-efficiency lighting lamps will be popularized throughout the country during the Ninth Five-Year Plan period.

by the year 2, we will strive to save 22 billion kwh of lighting electricity, save corresponding coal burning in power plants, and reduce the emissions of sulfur dioxide, nitrogen oxides, dust, ash and carbon dioxide. 11. Use renewable resources-don't wait until the day when energy is exhausted. 9% of the energy currently used by human beings is oil, natural gas and coal.

It takes hundreds of millions of years for these fuels to form, and they are non-renewable resources. Solar energy, wind energy, tidal energy and geothermal energy are renewable and are called renewable energy.

people call those energy sources that do not pollute the environment "clean energy". 12. Be a "public transport family"-be proud of riding public transport vehicles. There are nearly 1.2 million motor vehicles in Beijing, the capital of China, which is only 1/6 of that in Tokyo and new york.

However, the concentration of pollutants emitted by each vehicle is 3-1 times higher than that of similar foreign vehicles. 73% of hydrocarbons, 63% of carbon monoxide and 37% of nitrogen oxides in Beijing's atmosphere come from motor vehicle emissions.

13. Being a "cycling hero"-protecting the atmosphere, started with the first step. In Europe, many people are willing to go to work by bike in order to reduce the air pollution caused by driving. Such people are regarded as environmental defenders and respected. American newspapers often mobilize people to buy as many necessities as possible when shopping in supermarkets, so as to save gasoline and reduce air pollution.

The influential American Cycling Association has been calling for * * * to build bicycle lanes when building roads. In Germany, many families like to go out in the same car with their neighbors to reduce the emission of automobile exhaust.

In order to clean the air in the city, Tehran, the capital of Iran, has set a "selfless car day". On this day, the Iranian president and the citizens also
