Irrigated area dry land sheetflow type water drainage, regulation and storage purification wet land built system
The invention provides an irrigated area dry land sheetflow type water drainage, regulation and storage purification wet land built system. The system structurally comprises a dry land, gabion ridges, plant isolation belts and a regulation and storage purification pond wet land. In a water drainage period, water in the land sequentially flows through the gabion ridges, the plant isolation belts and the regulation and storage purification pond wet land in a sheetflow mode, and nitrogen and phosphorus nutrients, pesticide residue harmful matter in the water can be effectively intercepted and purified; in a rainfall period, the regulation and storage purification pond wet land can effectively regulate overland rainwater runoff in an irrigated area, and the flood pressure of a reception river is reduced; in an irrigation period, water in the regulation and storage purification pond wet land can be used for reuse. The irrigated area dry land sheetflow type water drainage, regulation and storage purification wet land built system has the advantages that non-point source pollution caused by irrigated area dry land sheetflow type water drainage can be reduced, farmland rainwater overland runoff and flood resources further can be effectively regulated, the construction process is simplified, popularization is facilitated, agricultural production can be remarkably improved, the ecological environment is protected, and sustainable development of the agriculture in an ecological irrigation district is achieved.
