黄河上中游流域泥沙优化配置研究

Study on optimal deployment of sediments in the upper and middle Yellow River basin

针对流域水土流失的灾害性、泥沙利用现状及泥沙优化配置的必要性,基于大系统分解-协调思想的流域泥沙优化配置原理与流域各子系统的泥沙多目标优化配置方法,构建了流域泥沙优化配置理论框架。进而建立了黄河上中游流域泥沙优化配置数学模型,该模型包括相互联系的各子系统、各分区和大系统三级泥沙优化配置数学模型,开展了不同水沙条件的黄河上中游流域泥沙优化配置方案计算,对计算结果进行了评价并提出了建议方案,为黄河上中游流域泥沙的科学治理提供了参考依据。

In view of the disasters of erosion loss, the current status of sediments utilization and the neces- sity of optimal deployment of sediments, a framework of optimal deployment theory of sediments in basin has been constructed on the basis of optimal deployment principles of sediments in basin by large scale sys- tem disaggregation-coordination idea and the optimal sediments deployment methods for multi-objectives in subsystems of basin. An optimal deployment mathematical model of sediments in the upper and middle Yel- low River basin was established which consists of interrelated sub-models at three grades： the subsystems, the subareas and the large scale system. The optimal deployment schemes of sediments were computed on various inflow conditions in the upper and middle Yellow River basin, the results were evaluated and the proposed schemes were provided accordingly which offered references to scientific management and harness- ing of sediments in the river basin.
