摘　　要：河流与地下水的相互作用是自然界中普遍存在的一种现象,也是陆地水文循环的一个重要组成部分。地下水对河流的补给与排泄不仅对河流的流量产生重大影响,而且也影响河流的侵蚀作用和沉积作用。通过试验验证了地下水潜水位与河床下伏隔水层对河流侵蚀能力的重要影响,并借鉴前人的研究,将地下水与河流的关系对河流沉积的影响划分为4种模式。通过研究现代玛纳斯河对地下水与河流关系的沉积响应,对河流河型分布进行了讨论。研究发现,地下水与河流关系的4种模式决定了河流河型分布。The interaction between the river and groundwater is a common phenomenon existed irr nature and it is also an important constituent of hydrological circulation of the land.The supply and drainage of the river caused by the ground water not only have a great impact on flow,but also affect the erosion and sedimentation of the river,especially the lateral erosion,this article takes the effect of the groundwater into consideration and tries to build four fluvial position model by the relationship between ground water and river.And then through the research of deposition response of Manas River that caused by the relationship between ground water and river,the allocation of river type is discussed.
