Water and soil conservation ecological management system for erosion badland
The invention discloses a water and soil conservation ecological management system for an erosion badland. The water and soil conservation ecological management system comprises a slope crest and a terrace arranged along a contour line, wherein a water and soil conservation forest used for controlling water and soil loss is arranged on the slope crest; water and soil conservation arbors are planted in the water and soil conservation forest; the terrace comprises a terrace wall and a terrace surface; a first planting area is arranged on the terrace surface; and economic plants are planted in the first planting area. Generally, the water and nutrient conditions of the slope crest of the erosion badland are poor; the water and soil conservation forest is planted on the slope crest of the erosion badland; rainfall runoff is intercepted; soil infiltration is increased; the water content of soil is increased; secondary distribution of the rainfall runoff is achieved; the utilization rate ofwater resources is increased; meanwhile, the coverage rate of vegetation can be increased; barren mountains are greened; the roughness of an underlying surface is increased; the runoff speed is reduced; the flow rate of surface runoff is reduced; the scouring capacity of the runoff is weakened; thus, the water sources are conserved, and the water and soil loss is reduced; and the first planting area is arranged on the terrace surface, and the economic crops are planted for greening and also can be utilized for increasing the income and recovering the cost.
本发明公开了一种侵蚀劣地水土保持生态治理系统，包括坡顶和沿等高线布设的梯田。坡顶设置有用于控制水土流失的水土保持林，水土保持林种植有水土保持乔木。梯田包括梯壁和梯面，梯面上设置有第一种植区，第一种植区种植有经济植物。一般情况下侵蚀劣地坡顶水肥条件较差，在侵蚀劣地坡顶种植水土保持林，拦截降雨径流，增加土壤入渗，提高土壤含水量，实现对降雨径流的二次分配，提高水资源的利用率，同时，可增大植被覆盖率、绿化荒山并增加了下垫面糙度，降低了径流速度，减小了地表径流流量，削弱了径流的冲刷能力，从而涵养水源、减少水土流失，梯面设置第一种植区，种植经济作物绿化的同时经济作物可利用，增长收入，回收成本。
