基于变异系数法的贵州省石漠化驱动力研究
Study on the Driving Forces of Rocky Desertification in Guizhou Province Based on Variation Coefficient Method
摘要
Abstract
[ Objective ] The aim was to study the driving forces of rocky desertification in Guizhou Province. [ Method ] Based on GIS and RS technology, the main driving forces of rocky desertification in Guizhou Province were analyzed by means of correlation analysis and variation coefficient method, and then the distribution of rocky desertification in Guizhou Province was assessed synthetically. [ Result] The main driving forces of rocky desertification in Guizhou Province were vegetation cover, rainfall, peasant income and gradient which were obviously correlative with rocky desertification; from the theoretical distribution of rocky desertification, rocky desertification was the severest in southwest Guizhou, Bijie, southern Guizhou and northeastern Guizhou, and the theoretical rocky desertification in Bijie was severer than current situation, which showed that the construction of ecological function area in Bijie restrained the development of rocky desertification effectively; the good consistency between theoretical and current distribution of rocky desertification revealed that our study method was feasible. [ Conclusion] The study could provide theoretical references for the practical control of rocky desertification.关键词
