摘要
随着我国对生态文明建设的愈加重视,矿山生态环境修复效果评估已成为其中重要一环。以北京王平煤矿为对象,采用Continuous Ordered Weighted Averaging(C-OWA)算子改进的综合指数法构建生态修复效果指数(Ecological Restoration Effectiveness Index,EREI),依据相关评价体系构建原则,综合考虑矿区生态修复中各生态因子及其相互之间的定量关系,从而探索性地建立一套具有代表性、系统性的评价指标体系,从工程区尺度进行监测评价;同时运用遥感信息解译计算的遥感生态指数(Remote Sensing Ecology Index,RSEI),从生态功能区尺度进行监测评价。研究表明,王平煤矿区生态环境修复效果良好,植被丰富度与覆盖度对研究区生态环境质量影响最大,与实地调研相符;EREI与RSEI指数计算结果分别为0.672和0.729,评价等级均为“良”。通过评价原则、指标分析等方面加以理论论证并结合实证研究,以期为后续矿山生态环境评价指标体系构建及监测相关研究提供参考。
With the increasing attention paid to the construction of ecological civilization in China,the evaluation of the effect of mine ecological environment restoration has become an important part of it.Taking Beijing Wangping Coal Mine as the object,the comprehensive index method improved by C-OWA operators was used to construct the ecological restoration effect index(EREI).And according to the construction principle of the relevant evaluation system,the ecological factors in the ecological restoration of the mining area and the quantitative relationship between them were comprehensively considered.to A representative and systematic evaluation index system was explored and established to monitor and evaluate from the scale of the project area.At the same time,the RSEI index calculated by remote sensing information interpretation was used to monitor and evaluate from the scale of the ecological function area.The results showed that the ecological environment restoration effect of Wangping Coal Mine was good,and the vegetation richness and coverage had a large effect on the ecological environment quality of the study area,which was consistent with the field research.The calculation results of EREI and RSEI indexes were 0.672 and 0.729,respectively,and the evaluation grades were"good".Through analysis of the evaluation principles,index,and other aspects of theoretical demonstration combined with empirical research,it provided a reference for the subsequent mine ecological environment evaluation index system construction and monitoring related research.
