Why should Dali’s Erhai Lake be protected?

Erhai is the second largest freshwater lake in Yunnan and the mother lake of Dali. It has nurtured the people around Erhai for thousands of years. Erhai Lake is not only the most important scenic spot in Dali, but also the largest source of water for living and production of people around Erhai Lake. Whether Erhai Lake can be protected is related to the well-being of the people.

In recent years, the local government has obviously realized this. It has also done a lot of work in the protection of Erhai Lake. It has established the Erhai Lake Protection Management Bureau, built some sewage discharge facilities, and proposed "protecting Erhai Lake like protecting your eyes." With slogans such as "Erhai Lake is clear and Dali is prosperous", the decision is made to "develop the east coast and protect the west coast", strictly control housing construction in rural areas around Erhai Lake, control agricultural pollution, etc.

However, Erhai Lake protection is a very large and systematic project, and the local government’s protection work has obviously not achieved the desired results. In other words, some decisions, laws and regulations proposed by local governments have not been effectively implemented and implemented. In terms of management, it is still not perfect and still lacks many loopholes.

The protection of Erhai Lake should be systematically planned from various aspects such as water sources, sewage discharge, and ecology. But in the past few years, the protection of Erhai Lake has basically been limited to building some local sewage facilities, salvaging garbage when it appears, putting up a few slogans, and doing a few publicity activities. No matter how much, it just keeps people's cows away. Some encourage rural areas to use organic fertilizers. These measures are basically the treatment methods used to treat headaches, head pain, and foot pain.

Even selective law enforcement and management have caused illegal construction along the Erhai Lake to get out of control, and direct discharge of sewage into the Erhai Lake has frequently occurred. People are not allowed to build houses, but companies are allowed to build high-rise buildings or even fill the sea, and people are not allowed to raise water. But Niu condoned the illegal mining of rocks and sand in the Erhai Lake source area, etc. Combing through the online news and information about Dali's Erhai Lake in the past ten years, this type of phenomenon is exposed almost every year. Even some local sewage discharge projects still have poor quality and cannot achieve the sewage discharge effect.

The Erhai Lake system belongs to a cyclic ecosystem, with water sources, wetlands, and various biological chains that rely on the Erhai Lake. Considering only pollution interception, it is obviously difficult for protection and treatment to have obvious effects when the water quality of Erhai Lake has been severely polluted in some areas.
