摘　　要：贵州属于典型的喀斯特地貌类型,山高坡陡,人口密度大,垦殖率高,暴雨多且强度大,是我国水土流失严重、治理难度大的地区之一。水利水电工程枢纽建筑物多,输水工程建筑物位置分散,涉及工程施工点多、站线长,相应弃渣堆置地点也较多。受地形条件限制,弃渣场选择较为困难。结合贵州土石山区特点,对贵州水利水电工程弃渣场选取和防护措施进行探讨并提出相应的建议。Guizhou belongs to typical karst landform,with high mountains and steep slopes,large population density,and high reclamation rate.There are often heavy rains of high intensity,it is one of the regions with serious soil erosion and difficult in treatment.Water conservancy and hydropower projects in this area is characterized by more structures,the location of buildings of the water conveyance project is scattered,there are many construction places with long distance,and there are many disposal area.Limited by the terrain conditions,the selection of disposal area is very difficult.This paper discusses the selection and protection measures of the disposal area of water conservancy and hydropower projects in Guizhou,and puts forward some suggestions in combination with the characteristics of mountain area.
