摘要
采用2001年IKONOS和2006年QuickBird遥感影像为主要数据源,结合1∶10 000地形图,利用遥感(RS)和地理信息系统(GIS)相结合的技术方法,以ERDAS IMAGINE和ArcGIS为操作平台,研究了鄂尔多斯市东胜区建成区的扩展情况.通过对遥感图像进行非定向边缘增强处理,计算出2001年和2006年建成区的面积、扩展速度和扩展方向.结果表明,东胜区建成区表现为高速扩展,随着建成区面积的扩展,城市质心也发生了转移.
The purpose of this work was to study the built-up expansion of Dongsheng district of Erdos City.Taking 2001 IKONOS and 2006 QuickBird remote sensing images as the main data sources,together with a 1∶10 000 topographic map,utilizes the technological method that combine remote sensing（RS） with geographical information systems（GIS）,and regard ERDAS IMAGINE and ArcGIS as the operating platform.Through Remote sensing image processing on non-directional edge enhancement,the area,the direction and speed of expansion were studied.Result showed that the expansion of the built-up area on Dongsheng District was in high-speed expansion,with the expansion of the area of the built-up area of Dongsheng District,the urban centroid was shifted.
