| The Zhangcheng and Zhangcheng Rivers in the upper reaches of Miyun Reservoir are important water supply sources and ecological barriers in Miyun Reservoir.Their functional orientation is "Beijing-Tianjin-Hebei Water Conservation Area." Focusing on this core orientation,this study focused on water source protection in the Anchungou small watershed in the upper reaches of Miyun Reservoir,and set up 5 forbidden signs in the ecological restoration area of Anchunou Small Watershed based on traceability and pollution control.There are 775,325 fish scale pit construction,367.52hm2 soil and water conservation forest,11.91hm2 renovation terraces,0.09hm2 village beautification,220 integrated domestic sewage treatment equipment,220 dry toilets and 7 new public toilets.Measures for Ecological Protected Areas There are trench cleaning treatment 9.7km,river bank management 3731m,wetland restoration 0.43hm2,protection dam 2965m.Taking the eco-clean small watershed measures system of ecological defense,ecological management and ecological protection as an example,this paper explores the construction of water source conservation area to build a coordinated development of Beijing,Tianjin and Hebei and build an ecological barrier to improve Ecological environment and water environment,protect the safety of the first drinking water source,beautify the rural environment and promote beautiful countryside construction Planning and design of eco-clean small watershed in the upper reaches of Miyun Reservoir and coordinate the development of ecological,economic and social benefits in this area,Collaborative development to make due ecological services,to provide the appropriate experience to learn from. |
