基于RS和GIS的建设用地变化研究——以重庆市主城九区为例
Research on the Change of Construction Land Based on RS and GIS ——Taking Nine Urban Districts of Chongqing as an Example
摘要
Abstract
By taking nine urban districts of Chongqing as an example, through using Landsat data in such eight periods as 1978,1985,1988,1993,1996,2000,2007 and 2009 and supported by 3S Technology ,this paper analyzes the studies on landscape pattern ,weight change and dynamic degree for construction land in the region from 1978 to 2009. The results show that construction land expansion in the studied area experiences rapid development period in the 1980s,slow development period in the late 1980s and the early 1990s, rapid development period from the late 1990s to the middle and late 2000s, and stable slowdown development period in recent years. In space, the weight of construction land in the studied area moves 2259.57 m more northwestward than in 1978. The research results are important reference to urban development.关键词
