| 摘 要： | 提出采用灰色系统理论中的灰色关联度分析方法对地下水脆弱性进行研究,选取地下水位埋深、包气带岩性、含水层砂层厚度等6个因子建立脆弱性评价指标体系,采用离差最大化方法确定评价指标的权重,使得权重的分配有了一定的理论依据。并以MATLAB为平台编制了常用计算程序,将其应用于抚州市地下水脆弱性评价与分区,取得良好结果。

| Abstract: | The Grey Correlation Method is applied to study the vulnerability of groundwater,the paper established the assessment index system,which was made up of the depth to groundwater,impact of the vadose zone,aquifer thickness,net recharge,groundwater quality,and pollutant headwater.The weight allocation is more reasonable to be determinedby applying the method of maximizing deviation.Based on the MATLAB,it developed several calculation programs,which is applied to evaluate and partition groundwater vulnerability... |
