农村生态环境承压能力区域差异与影响因素研究
Research on regional difference and influence factors on pressure-bearing capacity of rural ecological environment
【摘要】 为了探讨目前农村生态环境承压能力受地区条件差异呈现的异质性变化规律,基于2011年的省际面板数据,选用多指标评价体系,运用因子分析法对各省的农村生态环境承压能力进行了综合评价。结果表明,四川、山东和河南农村生态环境的承压能力位于全国前3位;北京、天津、上海位于后3位。在此基础上,结合农村生态环境水平评价矩阵对31个省区进行聚类,结果显示,四川、山东、河南等12地属于"承压能力强-高效益"型地区;甘肃、云南、内蒙古3地属于"承压能力强-低效益"型地区;广西、新疆属于"承压能力弱-高效益"型地区;陕西、西藏、江西等14地属于"承压能力弱-低效益"型地区。
【Abstract】 In order to explore regional difference in pressure-bearing capacity of rural ecological environment based on differences of area conditions, the article selects panel data of 2011 to make up multi-index evaluation system of rural ecological environment. The results of factor analysis show that Sichuan, Shandong and Henan are the national top three, while Beijing, Tianjin and Shanghai are located in national final three. Further more, we cluster 31 regions by constructing evaluation matrix on level of rural ecological environment. The results show that 12 areas including Sichuan, Shandong, Henan belong to "strong pressure-bearing capacity, high efficiency" area, 3 areas including Gansu, Yunnan and Inner Mongolia belong to "strong pressure-bearing capacity, low efficiency" area, Guangxi and Xinjiang belong to "weak pressure-bearing capacity, high efficiency" area, 14 areas including Shanxi, Tibet and Jiangxi belong to "weak pressurebearing capacity, low efficiency" area.
