What is the basic situation of Wulie River in Chengde City?

The 12 rubber dams in Wuliehe River are the largest rubber dam group in China. The 12-kilometer water landscape promenade connected by the 12 rubber dams has a water surface of 2.4 million square meters, which makes the urban residents enjoy an average of 1 square meters of water surface, showing the urban landscape belt with Chengde characteristics. The construction of rubber dams and dikes has raised the flood control standard of Wulie River to once every 2 years, and the Shuangfengsi Reservoir can reach once every 1 years after its completion, thus ensuring the flood control safety of cities, summer resorts and some surrounding temples. At the same time, the rubber dam group is also an important guarantee for the ecological water use of the summer resort, which can replenish more than 4 million cubic meters of water to the mountain villa lake area every year, which not only increases the water storage capacity, but also ensures the drinking water safety of residents.

The above is the above view, and the following is my personal view:

The water quality of Wulie River is bad. Every year at the end of May and the beginning of June, eutrophication makes algae grow wildly, and the organisms in the water decay, resulting in an unpleasant odor. Various sewage outlets discharge a lot of untreated sewage into Wulie River, both domestic sewage and industrial sewage, and drinking water is seriously threatened. Isn't the accident near Ganyang Hotel an alarm? Poor governance is the first reason, but it is ridiculous that the sewage treatment plant can't produce at full capacity.

Too many rubber dams turn living water into stagnant water, resulting in the loss of self-cleaning ability, and the fragile living environment of aquatic organisms hangs by a thread.

From the upper Erdaohezi to the bridge head of Dashimiao, there are fishermen everywhere. If you don't have 1, fishing rods, you have to have 8,. What's especially hateful is that the butcher who sells meat in front of Building 5 of Bilujiayuan, together with the land flow, openly drags nets for long-term filtering fishing, but the rubber dam managers of Chengde Bridge pretend to be blind there.
