土地利用结构信息熵时空变化分析——以宜春市为例

基于系统论的信息熵有关理论,对江西省宜春市土地利用结构的时空变化进行了研究。结果表明:(1)宜春市1997～2008年土地利用结构信息熵总体上呈上升趋势,土地利用结构缓慢向均衡状态发展。(2)根据2008年信息熵空间分布差异,将宜春市土地利用结构变化分为3个不同类型区域。(3)宜春市土地利用结构信息熵和均衡度在时空上的区域分异规律主要受区域自然环境条件和社会经济因素的影响。

Analysis of Spatial and Time Changes in Information Entropy of Land Use Structure——Taking Example for Yichun City

On the basis of the relevant information entropy theory in system theory, this paper analyzed the spatial and time chan- ges in the information entropy of land use structure in Yichun city, Jiangxi province. The results showed that： （ 1 ） During 1997 - 2008, the land use structure information entropy expressed an ascendant trend in general, and the land use structure slowly developed to a balanced state. （2） According to the spatial distribution difference of information entropy in 2008, the land use structure in Yi- ehun city could be divided into three types of areas. （3） The regional distribution rule of the land use structure information entropy and equilibrium degree in Yichun city in time and space was mainly influenced by the factors of regional natural environment and social economy.
