基于GIS技术和信息熵的宜兴市城乡土地利用空间结构变化分析

摘要

In this paper, according to the land use map in 2005 and the data of the second National Land Survey in 2009, the spatial structure changes of urban and rural land use in Yixing city were analyzed based on GIS technology and Shannon entropy. The results showed that the Shannon entropy and equilibrium degree of land use spatial structure in Yixing city all appeared a decreasing trend, and the order degree of land use was increasing from 2005 to 2009.%基于GIS技术和信息熵原理,根据宜兴市2005年土地利用现状图和2009年第二次全国土地调查数据,对宜兴市城乡土地利用空间结构的变化进行了分析.结果表明:从2005年至2009年,宜兴市城乡土地利用结构的信息熵和均衡度均呈现出减小的趋势,土地利用有序度升高.
