摘　　要：为应对西峰区应急供水危机,提高供水保障能力,本文对巴家咀白垩系地下水水源地水文地质进行了系统的研究。根据含水层埋藏和分布特征,结合地下水补、径、排条件及动态变化规律,采用单项组分和综合指数两种方法对水源地地下水水质和可开采水资源量进行分析评价。结果表明:巴家咀水源地地下水的感官性状良好,达到了地下水标准Ⅲ类水水质要求,可做为城市生活及工农业用水水源。水源地承压水地下径流补给量大于设计开采量,且保证程度较高,开采地下水不会引发诸如地面沉降和地裂缝等环境问题。In order to cope with the emergency water supply crisis in Xifeng District and improve the ability of water supply guarantee,had carried out a systematic study on the hydrogeology of the groundwater source area of the Cretaceous in Bajiazui.According to the burial and distribution characteristics of aquifers,combined with groundwater replenishment,diameter,drainage conditions and dynamic changes,two methods of single component and comprehensive index are used to analyze and evaluate the groundwater quality and exploitable water resources in the water source area.The results show that the sensory properties of the groundwater in Bajiazui water source area are good,and it meets the water quality requirements of Class III of the groundwater standard,and can be used as a water source for urban life,industry and agriculture.The replenishment of confined water underground runoff in the water source area is greater than the designed mining volume,and the degree of assurance is high.The mining of groundwater will not cause environmental problems such as ground subsidence and ground fissures.
