摘要
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个因子建立了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,应用于抚州市地下水脆弱性评价与分区,取得良好结果。
The Grey Correlation Method is employed to analyze the vulnerability of groundwater. This paper established an 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 by applying the method of maximizing deviation to determine. Moreover, based on the MATLAB, it developed several calculation programs. On the attempt to assess and partition the groundwater vulnerability in Fuzhou City of Jiangxi Province, the result is satisfactory.
