Research on regional difference and influence factors on pressure-bearing capacity of rural ecological environment

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冶area, 14 areas including Shanxi, Tibet and Jiangxi belong to weak pressurebearing capacity, low efficiency area.
