邢台百泉岩溶地下水系统特征分析与开发利用研究

根据邢台百泉岩溶盆地中赋存的岩溶地下水补给快、循环周期短、水质好,同时流域内污染源容易污染岩溶地下水的特点,计算了岩溶水补给资源量,并对邢台市供水水质进行评价,结果表明,NO3 N检出率较高,可能与长期使用氮肥有关。阐明在开发利用岩溶地下水时应遵循其自然特性进行合理开采,还应通过人工调节、人工补给提高水资源的利用率。

Characteristics of karst groundwater system at Baiquan of Xingtai City and its reasonable development and utilization

Based on the characteristics of the karst groundwater at Baiquan, including fast groundwater recharge, short period of water cycle, high water quality, and liability to pollution, the volume of groundwater recharge is calculated, and the quality of water supply is evaluated for Xingtai City. The results show that the content of NO 3 N in the groundwater is high, which might be related to the long term utilization of nitrogen fertilizers. It is also clarified that the development and utilization of the karst groundwater should follow its natural characteristics, and the measures of artificial regulation and recharge should be adopted to raise the utilization ratio of the groundwater resources.
