河南省区域城市化与生态环境效应空间关系分析

运用熵权法对2012年河南省18个地市的城市化水平和生态环境效应进行综合评价,并在此基础上运用空间统计分析和GIS技术,探讨河南省区域城市化与生态环境效应的空间关系.结果表明:2012年河南省区域城市化水平与生态环境效应空间差异显著,且呈现较明显的负相关对应关系;通过空间自相关与空间关联分析,区域城市化与生态环境效应呈现全局性显著的相似区域间"趋同"的集聚特征;运用K-Means聚类分析将2012年河南省区域城市化与生态环境响应关系划分为5种类型.

Analysis of Spatial Relation between Regional Urbanization and Ecological Environmental Carrying Effects in Henan

A comprehensive evaluation of the urbanization levels and ecological environment effects in 18 cities of Henan province was made by the entropy method,and then the spatial relation between urbanization and ecological environment effects on the basis of the evaluation results was discussed by spatial statistical analysis and GIS technologies. The results showed that: 1) there were significant spatial differences between the regional urbanization levels and ecological environment effects in 2012,which appeared to be an obvious negative correlation; 2) through analyses of spatial autocorrelation and spatial relevance,the characters of agglomeration in similar regions were presented obviously between regional urbanization and ecological environment effects; 3) the relation between regional urbanization and ecological environment response of Henan province in 2012 was divided into 5 types by the use of the K-Means cluster analysis method.
