摘　　要：喀斯特石漠化是在喀斯特脆弱生态环境下,人类不合理的社会经济活动,造成植被破坏、水土流失、岩石逐渐裸露、土地生产力衰退丧失的演变过程,严重制约了区域社会经济的可持续发展。洗马河流域是织金洞国家级重点风景名胜区核心主成部分,主要岩性为灰岩和白云岩,喀斯特十分发育,是典型的石漠化区域,占流域面积近70%,人地矛盾十分突出。项目通过GIS与遥感技术为手段,进行石漠化调查和防治工程的布置,从而达到对该流域的石漠化防治,挽救该区域人类生存条件、防治水土流失、对国家重点风景名胜区的保护,同时对其它喀斯特区域石漠化的综合防治起着示范作用。Karst rock-desertification is under the fragile ecological environment of the karst, mankind＇s unreasonable social economic activities, cause vegetation destroying , soil erosion , rock uncovering gradually , development course lost that land productivity declines, have restricted the sustainable development of the social economy in the area seriously. Ximahe basin is key component of national scenic area of Zhijindong cave in the Ximahe River,the main rock is limestone and dolomitite. The karst develops very much, it is the typical rock-desertification area, accounts for nearly 70%, contradiction between people and land is very conspicuous. The project is on the basis of GIS and RS technology, carry on the arrangement of the rock-desertification investigation and prevention and administration project, thus reach the rock-desertification of the basin to prevent and administrate , save this regional human survival circumstances, prevent and administrate soil erosion, protect the national scenic area, playing an exemplary role to the comprehensive contorl of regional rock-desertification of other karst at the same time.
