面向生态的额尔齐斯河水库群中长期调度

Long-and mid-term ecological scheduling of reservoir groups

  • 摘要: 为解决水库群中长期生态调度问题,以新疆额尔齐斯河流域为研究对象,构建了水库调度的网络节点图,建立了面向生态的水库群中长期调度模拟和优化两种模型,分别采用历时水量平衡的自迭代模拟优化算法和大系统协调的动态规划方法求解。结果表明,中长期模拟和优化调度结果均满足流域水资源综合利用、生态供水及相应保证率要求,且优化调度模型计算的河道内外生态供水、北疆供水、农业供水等均优于模拟模型。同时,揭示了来水与生态供水的关系,制定了关键水库的生态调度图,建立了调度函数并通过合理性检验。研究成果对额尔齐斯河水资源综合利用、保障河道鱼类栖息地、河谷林草的生态安全提供了中长期战略支持,具有重要的理论意义与应用价值。

     

    Abstract: To resolve the problem concerning long-and mid-term ecological scheduling of reservoir groups, the Xinjiang Irtysh river basin was selected as the study object, and a network node map for reservoir scheduling was established. Long-and mid-term simulated reservoir group and optimum scheduling model oriented ecologies were established, and the two models were solved using the self-iterative optimal simulation and improved DP algorithms based, respectively, on water balance and big system methods. Results of the study demonstrate that the obtained water supplement adequately meets demands concerning comprehensive water-resource utilization, ecology usages, and the corresponding guarantee rate. Results obtained using the optimum model when applied to ecologies existing within and outside of the Xinjiang Irtysh river, Wulungu lake, Beijiang and agricultural irrigation was observed to be better compared to those obtained using the simulated model. At the same time, the relationship between incoming water and ecological supplements was revealed, and a reservoir operation chart was drawn. Additionally, an operational equation, which passed the rationality test, was set up. Results obtained in this study bear critical significance with regards to providing long-and mid-term strategies for comprehensive utilization of water resources and protection of the ecological security for the fish habitat and valley forests and grassland.
