基于信息熵与空间洛伦兹曲线的土地利用空间结构分析——以重庆市合川区为例
Analysis on Spatial Structure of Land Use on the Basis of Information Entropy and Lorenz Curves——A Case Study of Hechuan District,Chongqing City
摘要
Abstract
With the combination of the land use data of Hechuan District in 2009,applying the methods of information entropy,equilibrium degree,advantage degree and Lorenz curve,the land use current situation,issue of existence,and structure were analyzed.And,the land use spatial allocation of 30 towns was studied,which has great significance to guide land use reasonably and sustainably.The conclusions of this study are drawn as follows：（1）The information entropy of land utilization in Hechuan differs distinctly that it can be divided into three regions,including high information entropy district,middle information entropy district and low information entropy district;equilibrium level of land use structure reduced gradually in pace with the three parts;（2）The cultivated land and other land distributed proportionally,and garden plot,forest land and grassland concentrated relatively;（3）Thirty towns in Hechuan own their land use characteristics,making use of regional resources open featured industry to optimize land use structure.关键词
