摘要
层次分析法(analytic hierarchy process,AHP)为一种定性与定量分析相结合的综合性评价方法。以海南岛矿山开发状况与矿山地质环境遥感调查监测结果为基础,利用AHP法对海南岛矿山环境进行了分析评价。首先,对15个评价因子的相对重要性进行估测,计算权重与排序,建立矿山地质环境质量评价指标体系;然后,根据所计算的等级综合阈值,建立矿山地质环境综合评定等级;最后,通过分析研究,将海南岛矿山地质环境划分为4个等级:严重影响区、较严重影响区、一般影响区和无影响区。针对矿山地质环境严重影响区进行了野外实地检查验证,结果表明,该方法计算出的权重较合理,取得的理论分析评价结果与现实吻合度很高,该方法值得在矿山环境评价工作中推广。
Analytic hierarchy process(AHP),as a comprehensive safety evaluation method combined with qualitative analysis,has been used in many fields of safety and environmental science.Problems of environmental geology in mines are affected by many factors.This study focuses on the ecological environment evaluation of the mine by using data on land occupied and damaged by mines,according to the characteristics of mining combined with relevant information of Hainan Island.Ultimately,mining environmental grade is divided into four levels.Through field examination and verification,it is found that the theoretical value is very compatible with the actual situation.The results show that the weight calculated by this method is scientific and reasonable,and the evaluation is objective.This method is worth popularizing in mine environment evaluation.
