Abstract:

水土流失是指在水流作用下,土壤被侵蚀、搬运和沉淀的整个过程。近几十年来,人们对中国南方喀斯特地区的研究日渐深入。贵州省喀斯特地形特殊的水土流失是诸多因素造成的,诸如地质背景、气候背景、自然因素、人文因素等。石漠化是这一地区特殊水土流失的结果,其特殊性的研究意义在于获得适用于该地区水土流失特点的评价标准、研究方法和防治手段,最终指导石漠化防治工作。
The soil and water loss is a whole course that the soil is eroded, transported and precipitated. There were more and more research activities on south China Karst in the past decades. The distinctive soil and water loss of Karst topography in Guizhou province was caused by many factors, such as geological back- ground, climate background, special natural factors, human activities, and so on. Rocky desertification was the result of the distinctive water and soil loss of this area. The researches on its distinctiveness aimed to ob- tain evaluation standard, research methods, soil and water conservation measures applied to Guizhou Karst, which would help to prevent and control rocky desertification.
