摘要
在阐述衡水地区水文地质背景的基础上,根据采样所得水化学数据,采用Piper三线图法分析了浅层地下水水化学特征,并对其矿化度多年变化对比及其与主要离子关系进行相关分析和直线回归分析,得出研究区水化学类型和成因虽然复杂,但近些年受降水和开采等因素影响,浅层地下咸水存在明显淡化趋势的结论;继而通过对其成因机制的探讨,认为研究区浅层地下水是大陆盐化与海水入侵双重作用叠加的结果。对浅层地下水的开发利用技术方法及前景进行了展望,认为研究区浅层水具有广阔的开发利用前景,具有重要的现实意义。
On the base of expatiation the background of hydrogeology in hengshui area, the article explains the chemical character of the shallow water by Piper 3 chart according to the data of samples, contrasts the changes of TDS in the years and makes the correlation analysis and linear regression analysis about TDS and its main ion relations, reaches conclusions that although the types of water chemistry and it＇s causes are complex in the research area but the unconfined salt groundwater are obvious diluting because of factors such as precipitation and mining effects in recent years; then the article discusses the cause mechanism and considers that the shallow salt groundwater is the results of superposition making by mainland salinization and seawater intrusion. The article makes a view on the development and technic of utilizing shallow groundwater and considers that there has a wide prospect, and it has important practical significance.
