金寨县位于大别山北坡,县境内地势陡峭,山峦起伏,沟壑纵横,相对高差1600米左右,多年平均降雨量1368毫米。由于雨量充沛,降雨强度大,加之山高坡陡,沟河比降大,地面切割严重。基岩大部分为花岗片麻岩和片岩,母质易风化,且风化物砂粒多粘粒少,抗蚀性差,保水保土保肥能力低,极易产生水土流失。为了探索适合金寨县治理水土流失的途径,1982年,淮委设立了黄榜试点小流域,经过三年的连
Jinzhai County is located in the northern slope of the Dabie Mountains, the county steep terrain, undulating hills, ravines aspect, the relative elevation of 1600 meters, the average annual rainfall of 1368 mm. Due to abundant rainfall, rainfall intensity, combined with steep mountain slopes, ditches lower than the ground cut serious. The bedrock is mostly granite gneiss and schist, the parent material is easy to weathering, and the weathered sand has less mucilage, poor corrosion resistance, low water and soil conservation ability, and soil and water loss. In order to explore ways for harnessing soil and water loss in Jinzhai County, in 1982, the Huai Committee established the Yellow River Pilot Basin and after three years
