摘　　要：2010年《永定河绿色生态走廊建设规划》拟利用北京城市段的门城湖、莲石湖、晓月湖和宛平湖,采用"生态补水型"的治理模式,建成1500km2的生态走廊,新增水面1000ha,绿化面积9000ha,每年回补地下水1亿m3,发挥再生水的"生态功能"。本文构建三个不同水文地质单元的溶质运移数值模型,模拟预测了河道利用再生水对周边地下水的影响。By building solute transport numerical model of three different hydrogeological system, this paper predicts the effect on the surrounding groundwater upon use of recycled water in the riverway. It shows that to utilize the reclaimed water in the transition zone and multi-layer area has a relatively small impact on groundwater, and reclaimed water in a simple layer needs to protect the water from infiltrating into riverway. In addition, river water quality should be strictly controlled during using the reclaimed water.
