[Explanation] The geographical location of Caohai National Nature Reserve is next to Weining County. According to relevant information, since 1950, large-scale local artificial drainage and land reclamation caused lakes to cause almost devastating damage to Caohai, and the area of Caohai has shrunk dramatically. By 1972, Caohai only had 5 square kilometers of water and some swamps. The forest coverage rate in the surrounding area dropped rapidly, and the Caohai ecosystem was on the verge of collapse.

Since our pollution has not been stopped, our urban domestic sewage is directly from Caohai. The black smelly water near the old city is very obvious.
[Explanation] The destruction of the environment has also brought many inconveniences to the lives of local residents. Aware of the seriousness of the local ecological and environmental damage, the local government has stepped up efforts to carry out Caohai ecological protection and comprehensive management. Like Li Zhenji, in that year, a group of young people joined the rectification team, and used a number of measures such as "pollution control, afforestation, returning farmland, and returning to the city" to control the mountains, water, and environment. From the second half of 2015, Caohai Has changed.

First of all, the water quality has improved, and the black and stinky water is gone. In addition, we were inferior to the five types of water bodies. The results of our monitoring this year have also reached the surface water. Secondly, the entire ecological environment is also developing in a positive direction. We protect the bird species represented by the flagship species Black-necked Crane. Our bird records have been recorded from 228 species in 2010 to 246 species. The species of birds are increasing, and the ecological environment is getting better and better.
[Explanation] In order to ensure that the water flowing into Caohai is clean, nowadays, 19 sewage treatment plants are scattered around Caohai. The water flowing into Caohai needs to be treated in more than 20 processes in the sewage plant. , And finally pass the test to be discharged.

Pull it out of the pool and monitor it with this equipment, because there is an emission standard, this value should be within the range, within the (specified range), it will be discharged to the artificial field, flow again, flow again Only then will it drain from the outlet to Caohai.
【Explanation】Every year in November, tens of thousands of birds will fly to Caohai to overwinter, including the rare black-necked crane unique to China. Green lake, blue sky, migratory birds foraging for food in winter, lingering birds for fun in summer. This "Pearl Plateau" inlaid in the hinterland of Wumeng Mountain has not only become a paradise for birds, but also a treasure in the hearts of local people.

After the ecological environment is improved, there are more and more birds coming, and it is becoming more and more cheerful. Through the establishment of protected areas and the implementation of these years of protection (measures), after many years of publicity, people now have a sense of protection . In the future, first of all, we must consider the issue of sustainable development. We will not follow the previous detours, and we will not destroy the environment first and then govern. As a protector, I hope (Caohai) can develop green and sustainable.
