Abstract:

The research of resources and environment carrying capacity is of great significance to the sustainable development of social and economy in ecological regions in China. In this paper, ecological health degree was used to describe the characteristics of ecological regions, the evaluation indexes system of resources and environmental carrying capacity was constructed, and the evaluation model of resources and environmental carrying capacity based on spring model and the method discretizing social and economic data were proposed to analyze the carrying state of resources and environment and the influence of social and economic pressure on the system of resources and environment in Chen Barag Banner of Inner Mongolia. The results showed that the resource and environmental systems of Baorixile Town, Huhenuoer Town and Bayankuren Town were all overloaded, and the values of RECS/RECC were 9.860, 1.369 and 1.221, respectively, while the others were all below 0.8. The evaluation results were reasonable and in accordance with the facts, which reflected the reliability of the evaluation method in the evaluation of ecological regions. The discretization result of social and economic pressure in 10 km×10 km spatial units was helpful to understand the spatial trend of social and economic pressure inside towns, which cannot be learned from the result based on the scale of township.

Key words: Chen Barag Banner, social and economic pressure, spatial discretization, resources and environment carrying capacity
