| 摘 要： | 以西南滇黔桂水土流失及石漠化遥感数据为例,并分别以我国西南岩溶区土壤侵蚀分级标准和国家林业局关于石漠化程度的界定标准为依据,运用层次分析法确定权重值,建立基于面积和权重的水土流失综合指数(WSL-CI)和石漠化综合指数(KDI),对西南滇黔桂水土流失强度与石漠化程度进行了动态研究。结果表明:西南各区的水土流失强度在总体上有减弱的趋势,而石漠化程度均有上升的趋势,这主要与水土流失强度和石漠化程度关系的复杂性、阶段性,岩溶区水土流失的隐蔽性和岩溶区水土流失解译结果存在误差有关。

| 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... |
