摘　　要：基于河道治理和生态恢复,围绕傍河取水时河水和地下水的相互关系,以北运河河道综合治理工程为依托,选取粉细砂为主的一段河道,通过数值模拟的方法研究傍河取水时对激发河水入渗能力和对地下水的的影响。一方面分析和验证了研究区用镜像法计算含水层渗透系数的适用性,另一方面预测了研究区傍河取水距离50 m、100 m、150 m时对河水和地下水的影响。结果表明取水井傍河越远,激发河水入渗的能力越弱,对地下水的影响范围越大,研究区傍河距离150 m时对河水的影响微乎其微,取水量主要来源于地下水。Based on river treatment and ecological restoration around interrelation between river water and underground water during riverside pumping. One section of BeiYun river which is a comprehensive treatment project channel dominated by silty fine sand as study area was chosen as an example. It has an effect on stimulated river infiltration capacity and also has influence on underground water when riverside pumping studied by means of numerical simulation. The results show that it is applicable to calculate aquifer permeability coefficient by mirror method in the study area, and on another hand the results show that it is different distance 50 m, 100 m and 150 m from riverside that is predicted to research water intake near the riverside and find out that the farther away the water intake well is from the riverside, the weaker the stimulated river infiltration is within the scope of simulation distance. when distance is 150 m, the effect on stimulated river infiltration capacity is very little and the abstracted water will maily derive from local underground water.
