基于AHP综合评价模型的潞安矿区生态承载力评价

Assessment of Ecological Carrying Capacity in Lu'an Mining Area Based on AHP Model

以山西省潞安矿区为研究对象,应用AHP综合评价模型,根据矿区生态承载力理论从生态系统弹性力、资源环境承载力及生态系统压力度3个方面建立了矿区生态承载力量化方法,构建矿区生态承载力评价指标体系并进行生态承载力评价。结果表明,潞安矿区的生态系统弹性度为37.31,属弱稳定;资源环境承载力为48.17,属中等承载;生态系统压力度为55.31,属中压状态。

Taking Lu’an mining area in Shanxi province as studying object,the quantitative method for assessing the ecosystem carrying capacity was established from the aspects of ecosystem elastic force,resource and environment carrying capacity by comprehensive assessment model,and ecosystem stress based on ecological carrying capacity theory of mining area;assessment index system for ecosystem carrying capacity of mining area was constructed and applied for environment carrying capacity assessment.The results showed that ecosystem elastic force of Lu ’an mining area was 37.31,demonstrating weak stability of Lu’an mining area ecosystem;the resources and environment carrying capability was 48.17,indicating medium carrying capability;and ecological stress was 55.31 which was medium level.
