摘　　要： 采用了多元线性回归分析法,从可能导致石漠化的自然条件因素和人文、社会经济因素入手,分析了贵州省土地石漠化形成与发展过程中的主导因素,并求出石漠化与因子之间的回归方程。贵州省的土地石漠化问题主要是由于人口增长和经济发展超过了环境的容许极限而引起的,岩溶生态环境只是为土地石漠化提供了必要的物质基础;回归方程对贵州省土地石漠化治理工作具有参考和借鉴价值。 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. And a regression equation between land rocky-desertification and factors was founded also. The land rocky-desertification problem in Guizhou Province was mainly caused by the population growth and economic development which are out of the environmental allowable limit. And the karst eco-environment is merely the material base of the land rocky-desertification. The regression equation will be of reference value to the work of the land rocky-desertification harnessing in Guizhou Province.
