基于ESDA的河北省资源环境承载力空间差异分析

Spatial difference analysis of resources and environment carrying capacity in Hebei Province based on ESDA

采用均方差决策法和探索性空间分析方法(ESDA),在ArcGIS和Geoda095i等软件平台上,对河北省城市资源环境承载力水平及空间差异进行定量分析.结果表明,自然环境承载力的空间分布具有明显的正相关性,呈现明显的全局空间集聚特征.Moran散点图显示自然环境承载力主要集中于第一、第三象限,处于正的空间关联关系,局部空间集聚现象明显.

By using the mean-square deviation decision method and the methods of exploratory spatial data analysis,by support of software ArcGIS10.0 and spatial statistical analysis software GeoDa095i,the spatial differences on the level of resources and environment carrying capacity of 11 prefecture-level city in the Hebei Province was analyzed.The results showed that the spatial distribution of natural environment carrying capacity showed significantly positive correlation and significant spatial cluster on global level.Meanwhile,Moran scatter plots of natural environment carrying capacity indicated that the most of the 11 cities focus on the first quadrant and the third quadrant,which mean exist a positive local spatial auto-correlation and significant local spatial cluster.
