摘　　要：以土地利用类型图及遥感影像为基础数据,利用GIS技术对石林景区岩溶湖泊湖滨带3 a土地利用类型进行遥感解译与制图,在此基础上运用景观类型指标和景观格局指标对研究区22 a间土地利用变化进行统计分析。结果表明:从1982-2004年湖泊面积减少215.05 hm2,除有林地面积持续增长及城乡、工矿、居民用地面积增加以外,其他土地利用类型面积均不同程度的减少。另外,除1982年其他未利用土地全部开发以致该地类消失以外,其他土地利用类型斑块数量均显著增加。景观破碎度指数明显增长,人类生产生活对湖滨带土地利用影响重大。Based on land use type maps and sensing images, a remote sensing map of the lakeside zone of karst lakes in stone forest was drawn and interpreted by using GIS technique. Landscape type index and landscape pattern index were used to analyze land use changes in the study area in the period of 22 years. The results showed that the area of lakes reduced 215.05 hm^2 from 1982 to 2004, and areas of other land use types reduced more or less except woodland and construction land. In addition, unused land in 1982 had been used entirely but the number of other land use types increased. Landscape fragmentation index increased obviously, and humaninduced production exerted significant influence on land use in lakeside zone.
