通过对区域水文地质条件、地质钻探、物探和水文地质抽水、单井回灌、渗坑入渗、示踪试验等资料的综合分析，对保定市一亩泉水源地水文地质条件进行了系统研究，查明了地层岩性、地质结构及地层渗透性等基本参数，为地下水回灌方案设计提供了可靠依据。研究结果表明，入渗场80m深度内揭露含水层7~8层，含水层岩性主要为卵砾石，渗透性较好，是较理想的入渗场地；回灌水有利于补给第1~2含水组，回灌水向西南方向流失及向下部3~4含水组渗流的可能性很小；入渗场垂直渗透系数为37．16~39．79m/d，单井影响半径为199．53m。

By the comprehensive analysis of the data about regional hydro-geological conditions, geological drilling, geo-physical prospecting, hydro-geological pumping, single well recharge pits, infiltration and tracer test, the hydro-geologi-cal conditions of Yimuquan source in Baoding city was studied, basic parameters were identified, such as permeability, formation lithology and geological structure. A reliable basis is provided for groundwater recharge design. The results show that there are 7~8 layer aquiclude within infiltration field in 80 meters depth, the lithology is mainly composed of gravel, the permeability is good, and it is an ideal infiltration field; the first and two aquifer is firstly supplied by reinjection wa-ter, the possibility of recharge water losing to the lower three or four aquifer is very small; the vertical permeability coeffi-cient of infiltration field is 37.16~39.79m/d, the influence radius of single well is 199.53m.
