| 摘 要： | 石家庄市地下水盐污染研究具有典型示范性。文中在地下水污染特征分析基础上 ,对盐污染的区域空间展布及其形成条件、盐污染的化学机制和地下水开采的影响进行了研究。结果表明 ,盐污染对石家庄市地下水水质有重要影响。其中NO-3 污染和硬度升高是构成该区地下水环境污染的主要因素 ,二者之间存在着密切的内在联系 ,阳离子交换作用和硝化作用是其重要机制 ;地下水超采是地下水盐污染的重要诱发因素。

| Abstract: | Shijiazhuang is a representative city for the study of groundwater salt pollution Based on the analysis of groundwater pollution features, this article mainly takes studies of salt pollution, including its spatial distribution and the formation conditions as well as the chemical mechanism and the impact of groundwater exploitation on it The results indicate that salt pollution has caused serious deterioration of groundwater quality The outstanding characters of salt pollution are the NO - 3 pollution and the rise of water hardness and there is a close relation between the two characters Cation exchange and nitrification are main types of mechanisms of groundwater salt pollution and over exploitation of groundwater is the important induce factor |

| Keywords: | Shjiazhuang groundwater salt pollution mechanism of salt pollution over exploitation of groundwater |
