Abstract

Guangxi is one of the less developed areas in China. With increasing population and accelerating regional

exploitation, water erosion desertification has become increasingly serious. The peculiar lithology and structure of

Guangxi are likely to form specific physiognomy. This paper holds that there exists direct effect of physiognomy, lithology

and structure on water erosion desertification in Guangxi, with the physiognomy being the primary factor in this aspect.

Based on GIS analysis, the authors have found that the water erosion desertification is mostly distributed in such areas

as carbonate, granite, mudstone and gritstone. The area of carbonate is most serious in this aspect, possessing 46% of the

total desertification area. This paper has analyzed the lithology, structure, physiognomy of the desertification area. Some

logical control countermeasures are also put forward in this paper.
