摘要/Abstract

摘要：

以Landsat TM/ETM卫星遥感影像为数据源,以GIS为分析手段,通过扩展面积、扩展强度指数、分维数指数以及相关用地类型的土地资源分布重心坐标详细分析了常熟市建设用地 (城区、城镇以及独立工业用地) 的时空特征,揭示了我国苏南经济发达地区城镇建设用地的扩展规律,分析了引起城镇建设用地扩张的驱动力。结果表明：(1) 撤并的建制镇镇区扩展强度远低于建制镇,但用地没有萎缩；(2) 建设用地加速扩展,但不均衡,分散格局没有改变；(3) 以市区为中心,以新港镇为副中心的城镇工业带和镇区连绵区正在逐渐形成；(4) 用地扩展从中心城区及周边为主,开始向沿江区域拓展；(5) 经济发展的速度始终是常熟市区各研究时段用地扩展的主导影响因子,相关政策指引着经济发展的方向,贯穿于常熟城镇用地扩展的全过程。

Abstract:

The tempo-spatial processes of the construction land, which includes urban area, town area and unattached industrial land area in Changshu city are analyzed in detail. The Landsat TM/ETM satellite images, which were respectively acquired in August 1984, October 1988, June 1994, May 2000 and July 2002, are used to digitize the area of the needed land use type with the help of GIS, which is also the main tool for analyzing the town and construction land growth data. The results are as follows: (1) the growth intensity of the common towns is less than one of the administrative towns, but the area of the common towns is not reduced. (2) The growth speed of the construction land is being accelerated, but spatial pattern of growth is not balanced and is dispersive. (3) The industrial strip and the uninterrupted zone of town is being engendered, the kernel of which is the city area and sub-kernel is Xingang town. (4) The growth of construction land is transforming from the city proper and its surrounding area to the towns along the Yangtze River. (5) The economic growth with high speed has always been one of the most important factors affecting land growth, and the correlative policies directing the economic growth run through the town land growth from beginning to end.

Key words: town, land growth, developed area, Changshu, remote sensing
