中文摘要	根据碳酸盐岩溶蚀速度、成土过程特点和岩溶区岩石组成比例,确定了广西岩溶区的土壤允许流失量为68吨/平方公里×年,并进行了土壤侵蚀分级,编制了广西岩溶区土壤侵蚀分布图。广西岩溶区在严重的土壤侵蚀作用下,土层渐薄,裸岩地遍布,水土俱缺。这是当地贫穷的主要原因。
英文摘要	There are different point of view for soil erosion in karst area. The former view is that thesoil erosion is not serious,due to lo silt content of river and low amount of soil erosion. Actuallythat is not so.The characteristics of carbonate rocks are that the erosive process is mainly corroded andformed process of soil is very slow. According to corroded ratio and content rate of carbonaterocks count up promise amount of soil erosion which is 68 t/km2·y in karst area of GuangxiAutonomous Region. The indices of soil erosion class in karst area of Guangxi are determined: insignificant erosion <68 t/km2·yslight erosion 68-100 t/km2·ymoderate erosion 100-200 t/km2·ystrong erosion 200-500 t/km2·ysevery erosion >500 t/km2 · yThe soil erosion sketch in karst area of Guangxi was mapped in this paper. Thus it can beseen that the soil erosion is serious ’in karst area of Guangxi.As a result of soil erosion of karst area,the exposed rock is distributed widly and both soiland water are lack. The serious soil erosion is important cause of poor of people in karst area ofGuangxi.
