灰色关联度法在盘锦市曙光地区地下水水质评价中的应用

Application of degree of grey incidence analysis on groundwater quality evaluation in Shuguang area of Panjin City

为了解辽河油田区域水资源环境背景和地下水水质变化趋势,本文选取盘锦市曙光地区6个水源地多年地下水水质监测资料,应用灰色关联度方法对地下水水质进行综合评价,结果表明近20年来,该区地下水水质逐渐变差,集中表现在Cl-和总矿化度较高,主要原因为油田污染及海水入侵等。

It is important to know the background and variation trend of regional water resources environment. The monitoring data of six water sources in Shuguang area of Panjin City were selected and evaluated by degree of grey incidence analysis in the paper. The results show that groundwater quality of this area changed worse in the last two decades. Contents and TDS are relatively high in the groundwater due to the oilfield pollution and seawater intrusion.
