| Abstract: | Ecological economic region Of Poyang Lake is of important significance in regional coordinated development and Jiangxi＇s rising. This paper takes the region as a case. Firstly,it sets up the index system on the utilization of the cultivated land. Secondly, it analyzes the differences and characteristics in space from the utilization of the cultivated land by the principal component analysis, cluster analysis and correlation analysis. The results show that the big differences in space from the utilization of the cultivated land in the region. And analysis means that the 6 indicators, such as forest coverage rate, food per capita and so on, are the main factors to control the comprehensive benefit for the utilization of the cultivated land. |
