沂沭河生态流量调度原则探讨

Discussion on principles of ecological flow scheduling of Yi River and Shu River

针对沂河、沭河水利工程运行现状及其引起的生态环境问题,基于《淮河流域生态流量(水位)试点工作实施方案》中提出的主要控制断面的生态流量指标,探索性地开展沂河、沭河生态流量调度研究。重点探讨了沂河、沭河生态流量调度中均衡利用、非完全保障等原则及调度措施,分析了生态流量调度中存在的问题,并提出相应的建议,以期使相关研究更具可操作性。

The running status of water conservancy project of Yi River and Shu River causes some ecological and environmental problems. And the ecological flow index of main control sections on Yi River and Shu River are based on the implementation plan of pilot work of ecological flow （water level） in Huaihe basin. The authors develop exploratory research concerning ecological flow scheduling of Yi River and Shu River, based on the ecological and environmental problems and eeologieal flow index of the main control seetions. This paper focuses on the principles of balanced utilization and non-complete guarantee, as well as the scheduling measures. The existing problems in the ecological flow scheduling are analyzed, and the corresponding suggestions are put forward so as to make the related research more operable.
