摘　　要：城区型水库是城市重要的供水水源,保障其水质安全极为重要,合理的水量调度方法能够有效改善水库水质状况。研究以深圳市西丽水库为例,分析了其在深圳市供水网络当中的重要性,并基于MIKE21软件构建了西丽水库二维水动力水质模型,在可用水量固定的前提下,提出了多种入库水量方案;再以总磷和总氮为例,对水库内水动力和水质消散过程进行了模拟,分析得到了一种适合日常调度使用、可有效加快水体净化的最优入库流量方案,为西丽水库发生水质污染时的应急水量调度提供了科学依据。Urban reservoirs are important sources of water supply for cities,and it is extremely important to ensure the safety of water quality.Reasonable water volume scheduling methods can effectively improve the water quality of reservoirs.Taking Xili Reservoir in Shenzhen as an example,the importance of the reservoir in the water supply network of Shenzhen is analyzed,and a two-dimensional hydrodynamic and water quality model of Xili Reservoir is constructed based on MIKE21 software.Taking total phosphorus and total nitrogen as examples,the hydrodynamic and water quality dissipation processes in the reservoir are simulated by a variety of inflow schemes proposed under the premise of fixed available water volume,and an optimal inflow scheme suitable for daily operation and effectively accelerating water purification is obtained,which provides a scientific basis for emergency water volume regulation in case of water pollution in Xili Reservoir.
