Characteristic agriculture production and non-point source pollution interception ecological system in reservoir area

The invention provides a pollution interception ecological system in a reservoir area. The ecological system is characterized by comprising a forest belt, a pasture belt and an aquatic fish belt, the aquatic fish belt is located in the reservoir area, the pasture belt adjoins a water bank, and the forest belt surrounds a land bank on the periphery of the pasture belt. The recycling agriculture ecological system with the surrounded reservoir and multiple symbiotic services is built successfully. Circular economy patterns such as 'livestock-biogas-fruit-residue-feed', 'fruit-residue-fertilizer', 'livestock-biogas-fruit-grass' and hydrological cycle are utilized, a reservoir bank biogas project, an economic forest belt and a flood intercepting project are built, the interception system for the hydro-fluctuation belt pasture belt, reservoir area freshwater fishes and the like is built, the cyclic regeneration principle and multilevel utilization of materials are achieved, comprehensive effect of the various industrial belts, multi-layer circular chains and multi-layer interception screens can be played in the production process of characteristic farm products, and the agricultural production mode with little waste being produced and the high resource utilization rate can be achieved.
