摘　　要：取水影响分析是取水许可的关键环节,对实现水资源合理开发与下游用水安全保障具有重要意义。笔者以广西某抽水蓄能电站为例,结合其用水工艺及调度运行方式,从水量平衡、水文情势、水体纳污能力、水生态和水事权益等多个维度,深入剖析运行期取水影响。研究表明:该电站取用水端的水量损失主要源于库区水面蒸发及渗漏,其余水量经生态流量管及竖井泄洪洞排至下游,且渗漏水量最终回归下游河道;在采取相应措施后,虽然对上下库坝上水文情势有一定影响,但对区域水体纳污能力以及坝下水文水资源情势影响甚微,下放生态流量完全符合现行规范及政策要求;涉及的水事权益问题已通过补偿措施妥善解决,整体取水影响较小。研究成果可为同类型项目规划建设提供重要参考依据。Water intake impact analysis constitutes a critical component of water abstraction licensing,holding significant implications for rational water resource utilization and safeguarding downstream water security.Taking a pumped storage power station in Guangxi as a case study,this research systematically investigates water intake impacts during operational phases across multiple dimensions:water balance,hydrological regime,water assimilation capacity,aquatic ecology,and water rights.The analysis integrates the station's water utilization processes and operational dispatch patterns.Findings reveal:Water losses primarily originate from reservoir surface evaporation and seepage,while residual flows are discharged downstream via ecological flow conduits and shaft spillways,with seepage ultimately returning to downstream channels;Post-mitigation measures implementation,although certain hydrological alterations persist in upper/lower reservoir areas,impacts on regional water assimilation capacity and downstream hydrological-water resource conditions remain negligible,with ecological discharges fully complying with current regulatory standards;Associated water rights conflicts have been effectively resolved through compensation mechanisms,demonstrating minimal overall intake impacts.This research can provide valuable references for planning and construction of similar projects.
