摘　　要：本文以大涧沟重点渗漏带为例,通过综合利用水文地质调查、遥感解译、直流电法物探测量、钻孔解译以及渗水试验等手段对趵突泉泉域沟谷型渗漏带的地形地貌特征、水文地质特征、植被覆盖度特征、第四系厚度特征以及地下水入渗补给量进行了研究。结果表明,大涧沟重点渗漏带地势整体上东高西低,南北两侧为山体,中间发育形成东西向的沟谷,为典型的沟谷型地貌;地下水流向整体上为自东南向西北径流;植被覆盖度整体上较高,中高植被、中植被和中低植被占整个流域面积的79.08%;第四系覆盖层整体较薄,厚度约0~20 m,地下水补给能力较强;现状开发利用条件下多年平均地下水渗漏补给量为192.37万m3/a。为保证重点渗漏带的渗漏量不减少,将重点渗漏带进行了功能分区,并有针对性地提出了不同功能分区的保护修复措施。In this paper, topographic and geomorphic characteristics, hydrogeological characteristics, vegetation coverage characteristics, the thickness of quaternary system and groundwater recharge are studied in Da-jian-gou gully-type key leakage zone of Baotu Spring domain through the comprehensive utilization of hydrogeology survey, remote sensing, the measurement of direct current prospecting, drilling, interpretation and water penetration test. The results show that the terrain of Da-jian-gou Leakage Zone is generally high in the east and low in the west, with mountains on both sides and east-west gullys in the middle, which is a typical gully type landform;groundwater flow is generally from southeast to northwest, and meteoric water can be directly infiltrated through limestone exposed layer to recharge karst water or indirectly through quaternary overburden. On the whole, the vegetation coverage is relatively high, accounting for 79.08% of the whole catchment;the quaternary overburden is relatively thin with a thickness of about 0~20 m, and the groundwater recharge capacity is relatively strong. Under the current development and utilization conditions, the annual average groundwater leakage recharge is 1.923,700 m3/a. In order to ensure the leakage of the key leakage zone is not reduced, the key leakage zone is divided into functional zones, and protection and restoration measures of different functional zones are presented.
