Erhai Lake is the mother lake of the Bai people in Dali. Located at the eastern foot of Cangshan Mountain in the west of Yunnan Province, Cangshan 18 flows into the lake in the west, with a lake area of about 246 square kilometers. Because its lake is shaped like an ear and the waves are as big as the sea, it is called? Erhai? .
Erhai lake used to be 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 jade; Leaf by leaf canoe across the quiet lake, rippling a string of tiny ripples, just like the blooming flowers on the lake? Erhai Lake at night is a mysterious reverie. The bright moon is in the sky, and the bright moonlight falls on Erhai Lake, just like a bright yarn in a cage? But now Erhai Lake has changed a lot.
Now Erhai Lake is no longer as crystal clear 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 row boats not to enjoy the scenery, but to listen to their mother's cry. Those ripples are like a sad tear of their mother. Now Erhai Lake is no longer a mysterious daydream, because it is turbid and no longer reflects the bright moon.
Erhai mother finally couldn't stand it and got angry. It broke the tenderness of the past and rolled up a huge wave on the lake. Those who are catching its ornamental fish are involved in the whirlpool of Erhai Lake, and everyone is aware of the seriousness.
Children of Erhai Lake! Is it so difficult to protect our mother Erhai Lake? When we protect Erhai mother, Erhai 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 without ruining her beautiful face and gorgeous clothes. People often say: Erhai Lake is clear and Dali is prosperous. ? You know, we are actually protecting ourselves by protecting Erhai Lake.
As descendants of Erhai Lake, we should remember: Protect Mother Lake? Erhai Lake is our responsibility.
Erhai Lake is protected at the foot of the majestic Cangshan Mountain, sparkling all year round, and silver, jade and jade complement each other. It is a famous scenic spot and nature reserve in China. She is our mother lake? Erhai Lake!
It is one of the seven freshwater lakes in China and the second largest lake in Yunnan. She makes Dali moist, with spring-like seasons and beautiful scenery; She is famous for her beautiful natural scenery and rich biological resources. She has created endless wealth for agricultural irrigation, industrial production water and urban domestic water supply, hydropower generation and water transportation, fishery breeding and tourism.
However, in recent years, the ecological environment of Erhai Lake has been destroyed, which not only threatens people's lives, but also affects the development of their hometown. The reason for this is the following：
1. Domestic pollution: Residents, restaurants, hotels and resorts around Erhai Lake randomly dump domestic garbage, discharge domestic sewage, and even throw animal carcasses into Erhai Lake. With the continuous improvement of rural life, there are more and more flushing toilets, and sewage is occasionally connected to Erhai Lake.
2. Agricultural pollution: In the agricultural production activities in Erhai Lake area, due to the extensive use of pesticides and fertilizers and the use of flood irrigation, a large number of fertilizers and pesticides were lost to Erhai Lake, which led to the increase of nutrients such as nitrogen and phosphorus in the lake water, which provided rich nutrients for algae reproduction and led to the outbreak of cyanobacteria in the whole lake. At the same time, it killed many creatures in the lake and made the lake stink.
3. Tourism and shipping pollution: There are nearly 5,000 fishing boats, dredgers and large, medium and small cruise ships in Erhai Lake, which produce sewage, garbage and oil pollution from various ships every day, causing water pollution.
For a better life tomorrow, for the smile of Mother Lake, for the clearer water, greener mountains and bluer sky in Dali, let's take active actions, start from the side, start from every little thing, and let's protect Erhai Lake together!
Protecting Erhai Lake There is a bright pearl on Dali Plateau in Yunnan? Erhai Lake. Located at the eastern foot of Cangshan Mountain, there are eighteen streams in the west. Because it is shaped like a human ear, it is called Erhai Lake. In the past, Erhai Lake was beautiful and pleasant, just like a graceful fairy. In the morning, the sun rises from the mountain on the east side of the sea, and the bright sunshine shines on the sea, sparkling. In the morning, the lake was as calm as a mirror at first. After a while, fishermen rowed boats and fished in Erhai Lake, only to see people throw down their nets and put them away quickly. Fish of different sizes jumped in the nets, and fishermen's hearty laughter came from the sea. At dusk, the sun is about to set, and the afterglow falls on the lake like golden powder. At night, the bright moonlight shines on Erhai Lake, as if covered with a layer of transparent yarn. At the same time, a bright moon is reflected in the water, rippling slightly with the water waves, which is famous? Erhai Moon? .
However, Erhai Lake is no longer a graceful fairy, but more like a roaring lion. Because human beings only ask for this mother blindly, but they don't take good care of her, people discharge industrial sewage and domestic sewage into the mother's lake, constantly dump domestic garbage, use phosphorus-containing washing powder, and throw dead animals into the lake at will? The water pollution in Erhai Lake is serious, which leads to a large-scale outbreak of cyanobacteria. Since people built the highway around the sea, the catering industry and tourism on both sides of Erhai Lake have developed rapidly. The sewage and garbage produced every day, as well as the oil pollution discharged by tourist boats, have aggravated the pollution of Mother Lake. Now the water in Erhai Lake is no longer clear and transparent. Standing by the sea, watching the floating blue-green algae gently patting the rocks on the shore, I seemed to hear the sad cry of Mother Lake.
