摘要泥沙对水库调度的影响是水库运行管理中不容忽视的问题。泥沙淤积会使水库库容损失,影响水库的供水、生态和发电等功能。泥沙调度需兼顾淤积与发电、生态、供水、防洪等多维目标。因此,泥沙动态调控的多维效益分析对实现水库综合效益最大化至关重要。以黄河干支流骨干枢纽群为例,提出多维效益指标,基于能值理论与经济学方法建立水库群泥沙动态调控的多维效益综合评价模型,运用该模型计算长系列年和典型年的不同调控方案下防洪减淤、供水发电、生态环境等效益。结果表明,长系列年中,古贤和东庄水库投入使用可提升流域综合效益,在不同典型年水沙条件下,投入古贤或东庄水库的方案均为最优调度方案。 The impact of sediment on reservoir operation is a problem that cannot be ignored in reservoir operation and management.Sedimentation causes reservoir capacity loss and affect the functions of water supply,ecology and power generation.Sediment management needs to take into account the multi-dimensional objectives of siltation and power generation,ecology,water supply and flood control.Therefore,the multidimensional benefit analysis of sediment regulation is crucial to maximize the comprehensive benefits of reservoirs.This paper takes the backbone hub group of the main tributaries of the Yellow River as an example,proposes the multidimensional benefit indexes,establishes the multidimensional benefit evaluation model of sediment dynamic regulation of reservoir group based on the energy-value theory and economic method,and uses the model to calculate the benefits of flood control,sedimentation reduction,water supply,power generation,and ecological environment under different regulation schemes in a long series of years and typical years.The results show that over a long-term series,the operation of Guxian and Dongzhuang reservoirs can enhance the comprehensive benefits of the basin,and under different water and sand conditions in different typical years,the schemes of commissioning Guxian or Dongzhuang reservoirs are the optimal operation schemes.
