遥感和GIS技术在贵州喀斯特地区土地石漠化研究中的应用

由于受人类活动影响 ,特别是土地资源利用的不合理 ,贵州省喀斯特地区出现了一系列的环境问题 ,一些地区存在的石漠化现象表现得尤为突出。故研究石漠化在贵州省喀斯特地区的分布、程度、成因等 ,对于加强生态环境建设的力度、制定资源环境人口经济协调发展的战略规划、水土流失治理等有重要的现实意义。通过应用多波段、多平台的遥感信息 ,在野外调研基础上与GIS技术支持下 ,对 2 0 0 0年遥感图像进行解译、编辑处理 ,制作贵州省喀斯特地区石漠化分布图 ,并分析影响其程度的主要参数及原因 ,为贵州省喀斯特地区生态治理及环境建设等方面提供依据

Application of Remote Sensing and GIS Technology for Land Desertification in Guizhou Karst Region

Guizhou is a province of Karst development, it is affected by mankind action especially, and it isn't unreasonable to using of land resource, flood disaster take place frequently. It lead to a series of environment problem. So people in karst region, if land desertification is serious, they are very poor. It enhances request of soil erosion work and building of ecological environment in karst region. The grade of land desertification is investigated and its space changeable, affecting parameters, causes and degree are analysed by GIS and remote sensing techniqu in Guizhou province, the map of land desertification in Guizhou karst region are made. Meantime, it is a completing way of science and technology, it is going to provide dependable data for soil erosion preventing and ecological environment managing.
