摘要
石家庄是我国北方利用地下水程度较高的城市,也是水资源危机较严重的城市之一。利用北调江水对其地下水进行补充调蓄,将极大缓解这种水危机压力。本文根据北调江水水源地丹江口水库的多年水质变化情况,结合受水区石家庄市的水文地质条件和地下水质特点,对其利用北调江水实施调蓄地下水后的水环境变化作了相关探讨。认为若以石家庄地下水降落漏斗为库容进行补充调蓄,将有效增加石家庄市的地下水资源量,提升其城市供水与储水能力。同时,还可明显改善其地下水质,提高地下水的自净化能力,恢复地下水的原始自然流向。为石家庄市的水资源调控提供科学依据。
Shijiazhuang is one of cities that are short of water in the North China. If the groundwater is recharged with water from the Yangtze River, the pressure of water demand will be relieved in this city. This paper makes analysis of the groundwater environment change with the groundwater recharged, according to the hydrogeologic condition and characteristics of groundwater quality. The result shows that if the groundwater is recharged with water from the Yangtze River under the precondition that the groundwater drawdown cone is considered as an empty groundwater reservoir, the water resource quantity will be increased obviously, groundwater quality will also be improved, groundwater self-cleaning ability will be enhanced, and former ground flow direction from northwest to southeast will come back.
