基于熵值法的成都市土地资源承载力评价

Evaluation of Chengdu Land Resources Load Capacity Based on Entropy Value Method

在介绍土地承载力概念的基础上,从土地资源人口承载力、建设规模承载力、经济承载力和生态承载力4个方面构建土地资源承载力评价指标体系。采用熵值分析法,对成都市2005——2013年土地资源承载力情况开展评价,结果表明:成都市的土地资源综合承载力一直处于稳步上升状态,但增长速度各年差异明显,其中2013年成都市土地资源综合承载力达到最高。

On the concept of bearing capacity of land, from the population bearing capacity of land resources, construction scale bearing capacity, economy carrying capacity and ecological carrying capacity in four aspects to build evaluation index system of land resources bearing capacity. Using entropy value method, the bearing capacity of land resources from 2005 to 2013 of Chengdu conducts evaluation, the results show that the evaluation period, the comprehensive bearing capacity of land resources of Chengdu has been increasing steadily, but the pace of difference to be markedly from year to year, and the comprehensive bearing capacity of land resources to achieve the highest of Chengdu in 2013.
