摘　　要：山区水循环研究不仅对山区本身,对与其相连的山前平原地下水的补给也具有重要意义。太行山区作为华北平原的重要水源补给区,其水循环现状以及对华北平原地下水的补给研究尚少,许多机理还不明确。研究通过阐述山区水循环过程与机理,结合地处太行山中段的牛家庄实验流域的实例研究,对太行山区对华北平原地下水的补给过程进行了分析。2004年4—11月的研究结果表明,牛家庄流域对山前的侧向补给量为1.53×106m3,补给系数(补给总量/降水总量)为0.242。流域的下游补给系数最大,中游次之,上游最小。最后,用概念模型对太行山区流域水循环机制和山前侧向补给的机理进行了阐述。Researches on water cycle in Taihang Mt. is vital not only to mountainous areas but also to groundwater recharge in adjacent piedmont.As one of the essential recharge sources for North China Plain （NCP） ,a few results on status of water cycle and groundwater recharge into NCP have been reported,and the associated mechanisms have not been revealed clearly.Here, the mechanism and recharge processes of water in Taihang Mt. to NCP,with a case study in Niujiazhuang Catchment and the nested Shimen Catchment within it which is located at the middle of Taihang Mt.,were presented.The results,from April to November 2004 for example, indicate the amount of lateral recharge from mountainous area to the adjacent piedmont was 1.53×10^6m^3 with recharge ratio （calculated by total recharge/total precipitation） of 0.242 in the order of upper reaches 〈middle reaches 〈lower reaches.Then,a conceptual model was used to illustrate the mechanism of water cycle in Taihang Mt. and the recharge to the piedmont.
