农村生态环境承载力的空间异质性变化

Spatial Heterogeneity Variation of Rural Ecological Environmental Carrying Capacity

为探明目前农村生态环境承载力空间异质性的变化规律,基于2011年的省际面板数据,运用因子分析法对选用的多指标评价体系进行了综合评价,并结合农村生态环境水平评价矩阵对31个省区进行聚类分析。结果表明:内蒙古、山东、辽宁、福建和江苏5省(区)农村生态环境承载力等级为"承载力好—经济效益好",河南、山西、湖南、广东和北京5省(市)为"承载力一般—经济效益一般",安徽、重庆、甘肃、贵州、青海和西藏6省(市、区)为"承载力差—经济效益差"。东、西、中部在农村生态环境承载力的空间分布差异与其地区经济发展情况基本一致。

The multi-index evaluation system was comprehensively assessed by the factor analysis method based on the data in 2011at the provincial level and 31provinces were analyzed by evaluation matrix of rural ecological environmental level to study the variation rule of spatial heterogeneity of rural ecological environmental carrying capacity.Inner Mongolia,Shandong,Liaoning,Fujian and Jiangsu provinces,Henan,Shanxi,Hunan,Guangdong provinces and Beijing city,and Anhui,Gansu,Guizhou, Qinghai,Tibet provinces and Chongqing city belong to good carrying capacity-good economic benefit type, common carrying capacity-common economic benefit type,and poor carrying capacity-poor economic benefit respectively.The difference of spatial distribution in rural ecological environmental carrying capacity among Eastern,Western and Central region China is not different with economic development status in other regions.
