| 摘 要： | 利用唐山沿海地区的工程地质、水文地质资料,以地质条件为背景,运用灰色聚类分析和模糊数学的方法,根据海水入侵地下水水质的特点,选择了Cl-、M、SO42-3项化学指标作为综合评价海水入侵程度的指标,侵染程度划分为4级;通过两种方法评价结果的对比,验证了唐山沿海海水入侵地下水水质评价的可靠性。

| Abstract: | Fully using engineering geologic and hydrogeological data, and taking geological condition in the coastal area of Tangshan as the background, the authors chose Cl~-, M and SO~ 2- _4 as chemical indexes to comprehensively evaluate the degrees of seawater invasion with the methods of gray cluster analysis and fuzzy mathematics and on the basis of characteristics of seawater intruding groundwater. The invasion can be grouped under four degrees. Through the comparison between the appraisal results from the two methods, we know that the appraisal is reliable for the quality of the coastal groundwater in Tangshan. |
