摘　　要：研究地下水环境的脆弱性,区别不同地区地下水环境的脆弱程度,定量化评价地下水环境潜在的易污染程度,警示人们在开发利用地下水资源时,有针对性地采取相应的防治保护对策.以银川平原水位埋深、净补给量、含水层介质、包气带介质、土地利用5项参数作为地下水脆弱性评价指标体系,结合地貌、地质、水文地质条件,按评价单元进行划分,对银川平原地下水脆弱性进行初步的综合评价和地下水脆弱性等级分区,可以帮助决策者和管理者制定地下水管理战略和方针,将有限的资金和人力直接投入到容易受到污染的地区,最大限度地保护地下水资源.Through studying the frangibility of groundwater environment and distinguishing frangibility degree of groundwater environment which is the quantitative assessment of the pollution degree in groundwater environment,people could be cautioned to take relevant counter measures of prevention and protection when they exploit and utilize groundwater resource.This paper advanced that taking buried depth of groundwater,net recharge,aquifer media,vadose zone media,land use as evaluation index system of groundwater frangibility,combining with landform,geology,hydrogeology condition,based on the evaluation unit,could make primary comprehensively evaluation and class zoning to groundwater frangibility of Yinchuan plain.It can help decision maker and manager to work out the strategy and policy of groundwater management,to put limited fund and manpower directly into the area which is easy to be polluted and to maximize the protection of groundwater resources.
