| 摘 要： | 利用大布苏地区1996年和2001年两个时相的TM遥感图像,获取不同时期的土地利用信息,分析了大布苏地区土地利用时空变化,借助FRAGSTATS软件进行了景观格局变化研究。研究结果表明,土地利用变化的总趋势是水域、荒草地减少,居民用地、耕地增加,土地利用综合程度指数降低;从景观尺度上看,斑块密度、多样性指数、优势度和均匀度指数减小,最大斑块指数、景观形状指数增加。

| Abstract: | Using the remote sensing images of Landsat TM in 1996 and 2001 of Dabusu area,information on land-use indifferent periods is extracted,and changes in land-use and landscape pattern of Dabusu area are studied. The main tendency of land-use change was that the areas of warter area and sward land decreased greatly,however,the areas of denizen land and cultivated land increased greatly.The comprehensive land-use index decreased remarkably. Landscape structure and landscape heterogeneity also changed greatly,for patches density,diversity index,dominance index and the evenness decreased.The largest patch index and the landscape shape index increased. |
