玉溪市资源环境承载力空间分布研究

Spatial Distribution of Resource Environmental Bearing Capacity of Yuxi

根据玉溪市的环境条件、资源状况、社会经济条件与区域资源环境承载力密切相关因素选取指标,建立玉溪市资源环境承载力评价指标体系,借助SPSS17.0软件,对玉溪市七县两区进行主成分及系统聚类分析.从分析结果看,玉溪市各县区资源环境承载力空间分布存在明显差异,其七县两区资源环境承载力空间分布可分为五类:红塔区为第一类,新平县为第二类,江川区为第三类,澄江县、华宁县、通海县为第四类,而易门县、峨山县、元江县为第五类.

An index system for evaluating the resource environmental bearing capacity of Yuxi city was established with indicators closely related with the environmental conditions,status of resources and social economic conditions of the region.With the system,the principal components and hierarchical cluster of the two districts and seven counties of Yuxi city were analyzed through SPSS17.0 software.The results show that there exists significant difference in the spatial distribution of resource environmental bearing capacity of these areas.And Hongta District falls into the first category,Xinping County the second category,Jiangchuan District the third category,Chengjiang County,Huajing County and Tonghai County the fourth category while Yimen County,Eshan County and Yuanjiang County are within the fifth category in terms of their resource environmental carrying capacity.
