摘　　要：通过系统分析2019—2020年3次生态补水的特点以及补水时平原南段两侧10 km范围内地下水位变化情况,分析补水对地下水位产生的影响,结果表明:对地下水位影响范围与补水的时长和规模呈正相关关系,且受到水文地质条件因素的制约。从涵养地下水的角度出发,建议生态补水的水资源应优先配置在京良路以上河段。本研究对于优化永定河生态补水的水资源配置具有重要的参考意义。This paper makes a systematic analysis of the characteristics of the ecological water replenish⁃ments and the changes of groundwater level within 10 km on both sides of the river from 2019 to 2020.By analyzing the influence of recharging on groundwater level,it is found that the influenced range of ground⁃water level is positively related to the duration and scale of recharging and is restricted by hydrogeological conditions.From the perspective of groundwater conservation,it is suggested that the water resources for ecological water supplement should be preferentially allocated in the reach above the Jingliang Road.This study has important reference significance for optimizing the allocation of water resources ecological recharge of Yongding River.
