摘　　要：对地下水资源的不合理开发会引发地面沉降、地下水位波动及水质恶化等问题。为此,借助层次分析法(AnalyticHierarchyProcess)确定了地下水资源开发过程中各环境致灾因子的权重系数,并以天津市塘沽区的多年观测数据为基础,建立了该区地下水资源开发的环境安全评价模型,最后对评价结果进行了分析。Unreasonable exploitation of groundwater resources will cause land subsidence, fluctuation of water level, and deterioration of water quality. Therefore, analytic hierarchy process was used to determine weight coefficiences of various factors causing environmental disaster during exploitation of groundwater resources, and the environmental security assessment model was established for groundwater exploitation based on observed data over years in Tanggu District of Tianjin. And finally, the results of assessment were analyzed.
