| Abstract: | The land ecological carrying capacity of Hunan province was analyzed and evaluated from the relationship among population, resources, environment, development in this paper, based on the results and information of land survey, geological survey, hydrogeology, environmental geology survey, soil survey, agricultural census, and used analytic hierarchy process and comprehensive index method, by analyzing block diagram spot, with geographic information system, remote sensing technology and the analysis of the mathematical model for the study of methods. The results showed that： the regional heterogeneity of land ecological carrying capacity of Hunan province was obvious, which was developed from low level of imbalance gradually to high level of balanced. |
