对矿山土地复垦综合效益进行评价,针对吉林省磐石地区建筑用石灰岩矿山特点建立了评价指标体系,采用层次分析法确定各指标权重,运用灰色系统理论,构建了建筑用石灰岩矿山复垦效益综合评价模型,并对3个典型矿山进行了效益评价。基于AHP分析和灰色综合评判方法,对研究区甲、乙、丙3个建筑用石灰岩矿的复垦效益评价为“良”“一般”“差”级别;该评价方法为石灰岩矿复垦效益综合评价提供了一条新途径,根据评价得出的“良”“一般”“差”级别,可以为地方管理部门评价已完成的矿山复垦,同时也为其他类型矿山复垦评价提供参考。
This paper evaluates the comprehensive benefits of reclamation of mining land. According to the characteristics of limestone mines in Panshi area of Jilin Province, the evaluation index system is set up. The analytic hierarchy process is adopted to determine the weight of each index. By using the gray system theory, the comprehensive benefits of reclamation of limestone mines are built Evaluate the model, and evaluate the benefits of three typical mines. Based on the AHP analysis and gray comprehensive evaluation method, the benefit of the reclamation of the three construction limestone mines in Grade A, B and C was evaluated as “good”, “average”, “bad”, and the evaluation method was A comprehensive assessment of the benefits of limestone mine reclamation provides a new way for local authorities to evaluate completed mine reclamation based on the “good”, “average”, “bad” levels of evaluation, and also For other types of mine reclamation evaluation provide a reference.
