| 中文摘要: |
| 再生水作为改善城市景观用水纳入河道，可其对地下水具有潜在的污染风险。通过构建区域地下水数值模型，应用质点追踪技术，计算出永定河补水区在河湖受水后地下水5 a运移1.47 km、20 a运移6.32 km，年均运移0.32 km。在数值模拟的基础上，依据地下水运移轨迹，结合区域水文地质条件，将研究区划分为核心监控区、二级监控区和控制监控区3个地下水监测分区，并提出各分区地下水监测井的布设原则及布设方式，实现地下水环境监测网络的优化。 |

| Reclaimed water,which was used as replenished water to improve urban landscape, was drained into river, while it have potential pollution risk to groundwater because of its complex composition.A numerical simulation of a groundwater basin was established,combining with particle transportation technology,to calculate the groundwater of Yongding River moving 1.47 km in 5 years and 6.32 km in 20 years,the average velocity is 0.32 km per year.Based on the particle transport model of groundwater numerical simulation,three monitoring districts were set: Core monitoring area,Second monitoring area and Control monitoring area,and presented the layout principle and the method of monitoring wells. |
