一、水土流失治理模式水土保持综合治理体系以生物措施和工程措施相结合治理方式,生物措施主要是营造水土保持林,恢复植被,截留雨水,防止降雨对裸露地带的直接冲刷,减少侵蚀源;工程措施主要是修筑拦沙坝,排洪沟,变水害为水利,拦蓄泥沙,减少泥石流对下游的直接危害;经过工程措施和生物措施,使小流域的生态系统得到恢复,使其逐步向良性方面转化,在缓地带进行坡改梯.形成耕地,在原
I. Soil and Water Loss Management Model Soil and water conservation integrated management system is a combination of biological measures and engineering measures. The biological measures are mainly to create soil and water conservation forests, restore vegetation and retain rainwater, prevent direct erosion of rainfall on bare land and reduce erosion sources; The engineering measures are mainly to construct barrage dam and flood discharge ditch, to turn water damage into water conservancy, to hold silt and sediment and to reduce the direct harm to the downstream from debris flow. Through the engineering measures and biological measures, the ecological system of small watershed will be restored to gradually Transformation of the benign, slope in the gentle zone to change the ladder. The formation of arable land, in the original
