咸阳市区傍河水源地水环境分析

Analysis of Groundwater Environment in Groundwater Resource Areas Near Surface Water in Xianyang City

应用模糊综合评价方法对咸阳市区傍河水源地水环境质量进行评价,并对水质的时空变化及其污染成因进行分析可得,由于地下水的过量开采,使得地下水水位持续下降,地下水流动力场发生变化,致使渭河污水和周围的劣质水向水源地流动,潜水污染严重,承压水中个别井也有潜在污染。

This paper studies the groundwater environment quality in water by fuzzy assessment and analyzes the change reasons in Xianyang city. It is concluded that due persistently and the dynamical field of flow to the groundwater resource area, groundwater resource area near surface of water quality with the time and space and contamination to the over exploitation of groundwater, the water level drops groundwater changes , which further cause Weihe River＇s polluted water and lead to the phreatic water quality polluted seriously and some wells of confined water also potentially polluted.
