摘　　要：以湘潭市城区作为研究区域,选用20世纪80年代末期、90年代中期和2000年3个时期已解译处理的TM遥感数据,利用景观格局研究方法,对区域土地利用变化的时空特征进行分析。在斑块水平上,通过计算斑块特征指数,包括斑块数、斑块面积等指标,结合相关统计资料运用GIS的空间分析方法得出区域土地利用景观单元特征指数,并利用土地利用转移矩阵探讨湘潭市城市化空间格局变化,讨论十年间城市化进程对该地区土地利用/覆被变化所产生的影响。可以看到至2000年,耕地面积占湘潭市总面积的37.56%,比80年代末期下降了1.10个百分点,合理加大耕地转化力度,城镇用地面积呈增长趋势,其中由耕地转化面积占5.17%,城镇用地面积稳固提升,为各种土地利用类型增长速度之首,增长幅度达1.79个百分点。同时有部分林地向耕地转化,所占比例为0.32%,耕地面积趋于动态稳定。This study takes the Xiangtan City as research region, and chooses the three period data of end of 80s, middle of 90s and 2000, using landscape pattern analysis method to research the spatial-temporal characteristics. By calculated the patches＇ number and area, it combines with the GIS technology and some statistics data to get the landscape pattern indices of the land cover, using land use change matrix to discuss the spatial pattern change of urbanization in Xiangtan City. It discusses about how the urbanization has affected the change of land use and cover in the past ten years. Until 20W, the proportion of cultivated land is 37.56% , it has declined 1.10 percentage, about 5.17% urban land is changed by the cultivated land, and the increasing area is the top of all types of land use, increasing rate reaches 1.79 percentage points . At the same time, about 0.32% wood land has changed to cultivated land, area of cultivated land tends to dynamic stability.
