基于1980s、1990s、2005年Landsat TM遥感影像和2010年欧空局(ESA)Globcover分类数据,运用RS和GIS技术及景观生态学方法,分析了1980s—2010年武汉市土地利用类型、土地利用动态度、土地利用景观格局的动态变化.结果表明:农地是主要的土地利用类型,地块连续性增强,成片分布;林地和草地1990s破坏严重,2010年区域植被得到一定程度的恢复;水域所占比重持续下降,减少速度之快,触目惊心;受城市化进程影响,1990s—2010年建设用地增长最快,呈规模化、成片发展;1980s—1990s未利用地得到大幅度开发,2010年未利用地面积明显增加且趋于成片化发展,地块连续性增强.
Combined with the integrated technology of RS/GIS technology and landscape ecological method, based on the Landsat TM image of 1980s, 1990s, 2005 and ESA’ Globcover data of 2010, this paper analyzed the changes of land use/cover and landscape pattern of Wu’han City form 1980s to 2010. The results show that agricultural land, which is continuous, is the main land use type. Forestland and grassland, which were partly restored in 2010, were damaged seriously in1990s. The proportion of waters decreased continuously from 1980s to 2010. With the promotion of urbanization process, construction land increased most rapidly from1990s to 2010. Unutilized land, which increased gradually large-scalely and continuously in 2010, developed greatly from 1980s to 1990s.
