太行山前平原地下水环境演化规律研究

The Environmental Evolution of Groundwater in Taihang Mountain-foot Plain of North China

本文依据河北省栾城县最新的浅层地下水水位埋深与水化学等资料 ,在综合分析研究区水文地质条件的基础上 ,系统分析了研究区内地下水水化学特征和地下水埋深分布情况。结果表明 :由于长期利用石家庄市的城市污水进行灌溉 ,区内地下水水化学场已发生明显的改变 ;长期的超采地下水 ,使得本区的地下水位埋深逐年增大。地下水的水化学特征和埋深特征表明 ,在解决本区的水资源短缺问题时 ,除考虑利用各种节水措施改变目前存在的传统灌溉制度外 ,还必须考虑区内污水灌溉对地下含水层污染的可能性 ,防止污染地下水。

Based on the buried depth and groundwater chemistry data in study area, the groundwater buried depth and water chemistry were analyzed systemically. The results showed that the characteristics of the groundwater chemistry have changed remarkably in some place where the farmland had been irrigated by sewage for more then 40 years, and the buried depth of groundwater increased year after year due to the over-exploitation. According to the distribution rule and characteristics of hydrochemistry and buried depth of groundwater, the countermeasures on agricultural water utilization especially the possibility of groundwater contaminated by sewage irrigation must be taken into account when soluting the problem of groundwater resource shortage in Taihang Mountain-foot Plain of North China.
