淮南煤矿区生态环境综合评价

摘要

Objective] To better understand the eco-environment quality in Huainan coal mining area.[Method] From the four aspects of natural environment, ecological status, environmental pollution and social economy, 16 evaluation indices were selected to construct the eco-environment evaluation system in Huainan mining area.Based on the index weight determination, comprehensive evaluation model of eco-envi-ronment quality was used to evaluate the eco-environment status in the years of 1986, 1999 and 2012.The eco-environment comprehensive e-valuation indexes in Huainan Coal Mining Area in1986, 1999 and 2012 were 66.536, 51.941 and 35.160, respectively, showing that eco-en-vironment quality in this region presented the change trend of worsening.[ Conclusion] Landscape fragmentation index, mining land collapse area and land stress index are the main negative indexes impacting the eco-environment quality of Huainan mining area .The Mining area eco-environment governance work in these areas should be given more attention in the future.%[目的]了解淮南煤矿区生态环境质量状况。[方法]从自然环境、生态状况、环境污染和社会经济等方面，选取16个评价指标构建生态环境评价指标体系。在确定指标权重的基础上，利用生态环境质量综合评价模型对1986、1999和2012年淮南煤矿区生态环境状况进行综合评价。[结果]1986、1999和2012年淮南矿区生态环境综合评价指数分别为66．536、51．941和35．160，表明该区域生态环境质量呈现出逐渐恶化的趋势。[结论]景观破碎化指数、矿区土地塌陷面积和土地胁迫指数是对淮南矿区生态环境质量影响最为不利的主要指标，在矿区生态环境治理中应引起重视。
