摘要: 水环境评价模型指标体系的选取和权重的确定是研究水环境承载力模型的关键.选取地下水脆弱性能，水环境质量，水体污染，开采程度，污染河水对地下水的影响等5个评价指标进行综合评价，利用层次分析法作为一种定量研究方法，运用专家评分法确定了评价指标体系中的各指标权重，并进行指标体系的可靠性和有效性判断，对区内地下水环境进行综合评价及可开采潜力分析.根据取得分值分区，确定承载力评价分区图，为地下水资源的合理利用提供了依据.Abstract: The selection of water environment evaluation model index system and the determination of weight are the keys to study the bearing capacity model. Based on five factors of groundwater vulnerability, water environmental quality, water pollution, exploitation degree and the effect of polluted river on groundwater, the comprehensive evaluation and exploitation potential of groundwater environment in the study area are analyzed, with AHP (analytic hierarchy process) as the quantitative research method, adopting the expert grading method to determine each index weight and judge the reliability and validity of the evaluation index system. According to the obtained assessment scores, the division map of bearing capacity evaluation is drawn for the rational utilization of groundwater resources.
