摘要
矿山地质环境评价往往受主观因素的影响较大。为提高评价的客观性和准确性,本文提出了一种基于耦合主观权重与客观权重的AHP-EWM综合权重的矿山地质环境评价方法。并以清镇市铝土矿区为例,利用遥感与地理信息系统技术,建立了3个层次、4个要素、14个影响因子的评价指标体系。基于综合权重相比主观权重或客观权重获取的矿山地质环境评分,矿山地质环境分区结果更能反映研究区矿山地质环境问题特征,可为清镇铝土矿区的地质环境管理和恢复治理提供依据。
Mine geological environment evaluation is often influenced by subjective factors.In order to improve the objectivity and accuracy of the evaluation,this paper presents an AHP-EWM comprehensive weighting method for mine geological environment evaluation,which is realized by coupling subjective weights with objective weights.Taking the bauxite mining area of Qingzhen as an example,an evaluation index system is established by using remote sensing and geographic information system technology.The system has three levels,four elements and fourteen influencing factors.The mine geological environment score and mine geological environment zoning results obtained based on the comprehensive weight can better reflect the characteristics of mine geological environ⁃ment problems in the study area than the subjective weight or objective weight,and can provide a basis for the geological environment management and restoration of Qingzhen bauxite mining area.
