摘要岩溶区石漠化是在喀斯特地貌基础上形成的荒漠化现象，而云南省的石漠化较为发育，分布在16个市。其中最严重的地区就是滇东南，某些地区已经达到了重度石漠化的级别。对滇东南岩溶区石漠化敏感性进行评价，能够很好的对岩溶区石漠化治理给予帮助。结合滇东南石漠化现状及相关资料，通过岩石裸露指数、植被类别、植被盖度、坡度这4个因子作为滇东地区石漠化评级指标。并且采取几何重心模型的方法来确定敏感性数值，从而定量化的对评价结果进行分级。32645
    石漠化敏感性评价对帮助相关部门采取治理措施是十分有效，通过制定合理的生态环境保护措施，对帮助地区的经济发展和实现社会的可持续发展起着积极作用。

Abstract   Karst rocky desertification area is the phenomenon of desertification in karst topography formed on the basis of, and Yunnan Province rocky desertification are well developed, distributed in 16 cities. One of the most serious areas is in Southeast Yunnan, which in some areas has reached the level of a severe rocky desertification. Sensitivity of rocky desertification in karst region of southeastern Yunnan evaluation, can be good for rocky desertification control in karst area to help. The status quo southeastern Yunnan desertification and related information, the bare rock, vegetation type, vegetation cover, these four factors as slope Diandong Rocky rating index. And take the geometric center of gravity model method to determine the sensitivity of the value, which can give the evaluation results classification.
   Rocky desertification of sensitivity evaluation to help the relevant departments to take measures to control is very effective, through the development of reasonable ecological environmental protection measures, to help regional economic development and to realize the social sustainable development plays a positive role.
Key words：Southeast Yunnan, desertification, sensitivity，evaluation factor

1.1  概述
石漠化简称“石质荒漠化”，是因为人类不合理的行为导致水土流失，植物被破坏，土地生产能力衰弱而导致的岩石慢慢裸露的过程。 滇东南岩溶区石漠化敏感性评价+文献综述:http://www.youerw.com/gongcheng/lunwen_29344.html
