摘要
以TM遥感影像为数据源,以武汉市主城区建设用地变化为主要研究对象,通过ENVI软件平台对2个不同时期的遥感影像进行土地利用分类和对比分析,揭示了武汉市建设用地扩张的空间特点。
Based on the RS technology, took the main urban district in Wuhan as study object, this article discussed construction land expanding through supervised classification and comparison of the two TM remote sensing images in 1991 and 2002 by using the software ENVI4.4, and the spatial distribution changes and the rules of alternation were revealed.
