以漓江三期补水工程体系为研究对象, 对漓江实时补水优化调度进行研究。首先基于马斯京根流量演算法建 立了供水水库群放水和控制断面需水的定量响应关系, 在此基础上提出考虑河道水流演进滞时和生态需水要求的 漓江水库群联合补水实时优化调度模型及相应的调度规则, 并通过约束处理技术使模型转化为能通过线性规划求 解的问题。实时优化调度模型在漓江流域的应用结果表明: 斧子口、川江、小溶江、青狮潭、五里峡、思安江六库联合 调度, 可以使特枯年份的供水日保证率达到 94% 以上。研究对维持漓江河道健康、提高通航保证率以及旅游经济 效益具有重要的意义。

Cho osing the thir d2phase w ater2tr ansfer pr oject as the research object, w e studied the r eal2time w ater2tr ansfer o ptimal operatio n in Li River Basin. First ly , w e built the quantitative r esponse relationship betw een the release of the w ater2supply res2 er voirs and w ater demand of the contr ol sect ion based on Musking umcs f low a lg orithm. Then we pr oposed a real2t ime w ater2 transfer optimal o per atio n model and co rr esponding operating rules fo r the r eser vo irs gr oup o n Li River, w hich to ok into co nsid2 er ation the water flow evo lutio n delay and the ecolo g ical water demand. T hr ough co nstr aint2handling t echniques, w e tr ansfo rmed the model into a question which could be so lved by linear programming. The application results showed that the joint operation of the six reservoirs on Li River ( including Fuzikou, Chuanjiang , Xiaorong jiang, Qingshitan, Wulix ia and Sicanjiang reservoirs) could raise the wa2 ter2supply daily assurance rate to abo ve 94% in especially dr y years. This study has important significance fo r maintaining a healthy riv er channel, increasing navigation assurance rate, and impro ving eco nomic benefits of to urism on Li River.
