1. Eco-clean small watershed construction: Miyun District started the eco-clean small watershed construction with the protection of the water source of Miyun Reservoir as the core, built three defense lines of ecological restoration, ecological management and ecological protection, and adopted 2 1 measures to implement the five-step control of "garbage, sewage, toilets, ditches and non-point source pollution", and gradually promoted the eco-clean small watershed construction of small watershed units.
2. Totally enclosed: 1 1 in 77 small eco-clean watersheds in the upper reaches of Miyun Reservoir is designated as the first line of defense, which is fully enclosed to reduce human activities and human interference and realize natural water conservation.
3. Sewage treatment: 4 1 village sewage treatment has been completed in Miyun District, and sewage treatment stations have been built in 53 villages. It is estimated that by 2023, the sewage treatment of the remaining 89 villages will be completed, and the conditional administrative villages will be fully covered.
4. Ecological river regulation: River regulation is carried out by ecological methods, and the river bottom is no longer lined with cement. Aquatic plants are planted along the banks of the river, and ecological frames are used for slope protection on both sides, water-retaining plants are planted, biological floating beds are made in the river water, and "experts" such as litchi, reed and calamus are planted to purify the river water, so as to improve the self-purification ability of the water body.
5. Promote water conservation according to law: formulate and implement a series of documents such as the Plan for Ecological Protection and Green Development of Miyun Reservoir Basin, set up a comprehensive law enforcement brigade for reservoirs, realize comprehensive law enforcement in specific areas, and provide legal protection for water conservation.
6. Water conservation by science and technology: five observation platforms for ecological water conservation and fire prevention in the first-class reservoir protection area will be built, and intelligent monitoring equipment will be installed to realize full coverage of water conservation and fire prevention monitoring in the reservoir area. The Miyun Reservoir Ecological Civilization Construction Research Center was established, and the first domestic large-scale reservoir water environment protection analysis system was built to comprehensively improve the efficiency of water source safety management.
The above measures are implemented together to protect the water quality and ecological environment of Miyun Reservoir.
