Karst soil rocky desertification is not only a geo-ecological disaster induced by karst geomorphy, but also a critical factor restraining social and economic development of Southwest China.

The resources of desertified soil and the effect of biological soil building measures in Hexi Corridor;

<Abstrcat> The geographic distribution, soil forming conditions, physico-chemical properties and main subgroups of desertified soil in Hexi Corridor are discussed.

Atlas analyses of karst land rocky desertification and ecological rehabilitation model;

The given eco geoenvironmental setting has evident control action on land rocky desertification, rocky deserted land mostly distributes in the river-valley regions where karst very developed and tectogenesis was violent in Guizhou province.

The phenomenon of land rocky-desertification is severe in Guizhou Province.

Based on the method of the multivariate linear regression analysis and started with the possible natural and social-economic factors, the main factors of the formation and development of the land rocky-desertification in Guizhou Province were found.

Based on the analysis of the reasons for land desertification in eastern surface hills of Erhai Lake,the paper discusses the type,distribution and area of the desertification land.

2 hm~2,including desertification land 36,679.

Analysis of spatial relation between rocky desertification and karst landforms in northwest Guangxi Province based on GIS and RS technology

It is helpful for understanding the process and rule of rocky desertification development to study the spatial-temporal distribution characteristics of rocky desertification.
