基于弹簧模型的资源环境承载力评价及应用——以内蒙古自治区陈巴尔虎旗为例

在全国生态文明建设背景下,资源环境承载力研究对生态型地区社会经济可持续发展有着重要意义。论文引入生态健康度描述生态型地区特点,构建资源环境承载力评价指标体系,提出基于弹簧模型的生态型地区资源环境承载力评价方法和社会经济数据离散化方法,以内蒙古自治区陈巴尔虎旗为例,分析2014年资源环境承载状况及社会经济压力对资源环境系统的影响。评价结果表明：宝日希勒镇、呼和诺尔镇和巴彦库仁镇资源环境系统超载,RECS/RECC分别为9.860、1.369和1.221,其他乡镇均低于0.8,评价结果有理可依,与事实相符,体现了评价方法在生态型地区评价的可靠性;社会经济压力在10 km × 10 km空间单元离散化结果与基于乡镇的评价结果不完全对应,方法优势体现在能够判别社会经济压力在乡镇内部空间上的变化趋势。

Evaluation of Resources and Environmental Carrying Capacity Based on Spring Model-Taking Chen Barag Banner in Inner Mongolia as an Example

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.
