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。
According to the disastrous situation of sediment and soil erosion, the current situation of sediment utilization and the necessity of sediment optimal allocation, based on the principle of large-scale system decomposition and coordination, the principle of sediment allocation in sediment basin and the multi-objective sediment allocation method The basin sediment allocation theory framework. Then the mathematical model of sediment allocation in the upper and middle reaches of the Yellow River has been set up. The model includes interconnected sub-systems, mathematical models for optimal allocation of sediment in the three sub-regions and large-scale systems, and muddy sediment in the upper and middle reaches of the Yellow River The calculation of sand optimal allocation scheme, the evaluation of the calculation results and the proposal scheme, which provide a reference for the scientific management of sediment in the upper and middle reaches of the Yellow River.
