为实现贵州省万亩大坝土地资源可持续利用，运用 GIS 技术、景观格局指数和主成分分析方法，通过对比湄潭县黄家坝大坝2000年 ETM、2005年 ASTER、2010年 ALOS 遥感影像，分析其土地覆被和景观结构的动态变化。结果表明：2000—2010年，大坝耕地持续减少，林地、城镇建设用地、农村居民点、道路、水域等面积持续增加，灌木林地呈先减后增的趋势，耕地主要转化成城镇建设用地、农村居民点和道路，大坝景观格局的破碎度和多样性指数增加，优势度减小，景观结构趋于多样和均匀化。耕地的稳定性值较低，林地的稳定性值较高，坝子土地覆被变化受人口、经济效益和产业结构因素的影响较大，政策因素也有一定的驱动作用。

To reveal the sustainable utilization of land resources in Guizhou 10 000-Mu basins, combined the integrated technology of ecological quantity analytical method with GIS technology,based on ETM image in 2000,ASRAR image in 2005,ALOS image in 2010,the authors conducted a quantitative analysis on the changes of land use/cover landscape pattern in Huangjia Basin.Results:Area of cultivated land continually reduced but forest land,rurban construction,rural dwelling land,water land and road land increased in different degrees from 2000 to 2010.But shrub land presented a first decreasing and then increasing trend.The major patterns of land use change were the conversion of cultivated land to rural dwelling land,land for urban construction and road.Both landscape fragmentation index and landscape diversity index decreased while dominance index reduced. Landscape structure became diverse and uniform.The cultivated land was the most unstable landscape,the landscape structure of forest land was the steadiest.The land use change/cover was affected by the population and economic factor.In the meanwhile,the adjustment of industrial structure and policy also had certain driving role.
