天津矿山复垦土地地质环境质量评价方法

摘要

针对天津矿山地质环境恢复治理现状及土地复垦生态重建的目标，筛选出19个评价因子，构建了一套由地质条件、土壤物理、土壤化学、土壤重金属组成的矿山复垦土地地质环境质量评价指标体系和分级标准。本研究采用五级划分，即分为：I级（好）、II级（较好）、III级（中等）、IV级（差）、V级（很差），并在此基础上依据天津市地质环境背景，以往工作成果以及相关技术标准，对影响矿山复垦土地地质环境的因子进行量化分级。提出了利用层次分析法（AHP）和模糊综合评判法来确定矿山复垦土地地质环境质量的评价方法，为矿山土地复垦监管、验收提供了更为科学、具体的评价方法。%According to the situation of the geological environment of the mine area and ecological reconstruction goal of land reclamation in Tianjin, the authors screened out 19 evaluation factors, constructed a set of geological environmental quality evaluation index system and grading standards including of the geological conditions, soil physics, soil chemistry, soil heavy metal of land reclamation. They propose to use the AHP and the Fuzzy Com-prehensive Evaluation to determine the quality of mine land reclamation geological environment evaluation meth-od,which provides more scientific, specific evaluation methods for the mine land reclamation supervision.
