Research on the Role of River Sluice Gate Scheduling Mode Optimization in Watershed Water Ecological Restoration
河道水闸调度模式优化对流域水生态修复作用研究

摘要

河道水闸是调节流域水量、水位和水动力条件的重要水利设施，其运行方式不仅影响防洪、灌溉、供水及排涝安 全，也直接改变河流纵向连通性、水体交换能力和水生生物栖息环境。本文结合典型平原河网流域运行参数开展情景 对比分析，结果表明，优化调度后河道生态基流保障率、水体流速、溶解氧浓度及水生生物适生面积均得到改善，水 位波动幅度和污染物滞留风险明显降低。研究可为兼顾防洪、供水与生态修复需求的河道水闸运行管理提供技术参考。

Abstract

River sluice gates are important water conservancy facilities for regulating water volume, water level, and hydrodynamic conditions in watersheds. Their operation modes not only affect flood control, irrigation, water supply, and drainage safety, but also directly change river longitudinal connectivity, water exchange capacity, and aquatic habitat conditions. This paper conducts scenario comparison analysis based on operating parameters of a typical plain river network watershed. The results show that, after optimized scheduling, the guarantee rate of ecological base flow, water flow velocity, dissolved oxygen concentration, and suitable habitat area for aquatic organisms are all improved, while the fluctuation range of water level and the risk of pollutant retention are significantly reduced. The study can provide technical reference for the operation and management of river sluice gates that coordinate the needs of flood control, water supply, and ecological restoration.
