Abstract

Abstract: Rocky desertification induced by soil erosion is a serious geological hazard in the karst regions of southwestern China. This paper made a research on small watersheds of Chengjiang River in Gongcheng County, Guilin City, Guangxi Province, analyzed the causes and trends of soil erosion in the regions by comparing rocky desertification areas in 1991, 2006 and 2015, and proposed countermeasures against soil erosion based on the above analysis. This research provides a basis for restoring ecological environments and preventing soil erosion in small watersheds of karst regions.
