摘要
为满足城市土地管理和规划的需要 ,本文针对我国城乡结合部范围不明确 ,管理难度大的特点 ,对城乡结合部的范围进行重新定义 ,构建出城乡结合部的地域结构模型 ;并且以无锡市为例 ,主要采用 2 0 0 1年 7月的Landsat 7卫星遥感数据 ,在ArcGIS和ERDASImagine软件的支持下 ,尝试提取出城乡结合部的精确范围 ,获取研究区内各个乡镇相对于城乡结合部的位置关系 。
In order to meet the need of scientific management and planning of urban land, moreover, considering the illegibility of the range of Urban-Suburban-Integration Area (URIA) and difficulties in managing it, this paper redefines the district range of URIA. Meanwhile, taking Wuxi as the case, the author tries to extract the exact range of URIA with the help of Remote Sensing (RS) and Geographic Information System (GIS) techniques. The primary data comprises Satellite imagery Landsat dated of July 2000, July 1998 and July 1991. The secondary data includes Administrative boundary of Wuxi, which is digitized vector data with GIS tool.
