蚌埠市土地利用及景观格局动态分析

Changes of Land Use and Landscape Pattern in Bengbu City

指出了安徽省蚌埠市是省内三大中心城市之一,近年来,蚌埠市经济发展与城市建设迅速,生态环境受到了一定程度的破坏,为了充分了解城市建设与土地利用和生态环境之间的动态变化,利用遥感(RS)及地理信息系统(GIS),以安徽省蚌埠市2000年和2005年两年的TM遥感影像为数据源,在ENVI以及FRAGSTAT景观格局分析软件的支持下,分析了蚌埠市土地利用变化信息以及其景观格局的动态特征。结果表明:5年来,从土地变化总体来说,城乡居民及工矿用地和耕地增加,未利用地减少,研究区受人为活动影响剧烈。

Bengbu City in Anhui province is one of the three central cities. For the past few years, the ecological envi-ronment has been destroyed with the rapid development of economic and urban constructions. This paper is aimed tofully understand the dynamic change between urban construction, land use and ecological environment. By using theplatform of Remote Sensing and Geographic Information System, we analyzed temporal--spatial feature of land usedynamic change and their ecological conditions in Bengbu citybased on remotely sensed images of Bengbu in 2000 and2005. The results showed that in the past 5 years, the main tendency of landuse change was that the areas of industryand mining land and weed land expandedwhile unused land reduced. The study area has been deeply affected by humanactivities.
