西南岩溶区水土流失与石漠化动态评价研究
Research on the Dynamic Evaluation of Water and Soil Loss and Rock Desertification in Karst Regions in Southwestern China
摘要
Abstract
Based on the soil erosion classification standards of epikarst which covers Yunnan, Guizhou and Guangxi in Southwestern China and discriminating standards of State Forestry Administration on rock desertification, by using analysis of hierarchy process for weights calculation, the paper establishes Water and Soil Loss Comprehensive Index(WSLCI) and Karst Desertification Index(KDI) based on the percentage of area and weights for dynamically evaluating water and soil loss intensity and rock desertification degree in Southwest China.The results show that: the water and soil loss intensity in each districts in Southwestern China is diminishing in the mass, but rock desertification degree in the same districts is aggravating, mainly due to the complex and periodical relationship between water and soil loss intensity and rock desertification degree,hidden water and soil loss in epikarst, and errors of water and soil loss caused by remote sense interpretation in karst area.关键词
