摘要
为反映主要污染物在水体中的分布特征,表征相应级别环境容量的地下水承载污染物的程度,揭示地下水水体受人类活动的影响程度,根据不同的指标对水质的影响不同而将它们分成3类,并用类间综合的方法确定了各类指标的单项评价指数和综合评价指数,建立了新的地下水水质评价模型。将该模型和灰色聚类法进行比较,本模型的评价结果既反映了水体中主要污染物的分布特征,又揭示了水质受人类活动的影响程度。
In order to reflect distribution of major pollutants in groundwater,to exposure the extent of groundwater carrying pollutant in the graded level for environmental capacity and to reveal influence degree of groundwater by human activities,the influential factors of groundwater quality were classified into three categories based on the different indexes,and the single index and the comprehensive index for the water quality were also defined.A new groundwater quality evaluation model was established.Comparied the model with grey clustering procedure,the evaluation can reflect distribution of the major pollutants in groundwater,and reveal the influence degree of groundwater by human activities.
