黄河干流泥沙优化配置综合评价方法

Method for comprehensive evaluation of sediment optimal allocations in the mainstream of Yellow River

  • 摘要: 按照泥沙优化配置评价指标应满足的科学性、系统性、层次性、代表性、定量性和可比性等筛选原则,初步构建了黄河泥沙配置评价指标体系框架,针对黄河泥沙空间优化配置的技术子目标和经济子目标,筛选了河道平滩流量、"二级悬河"高差、入海排沙比、水库拦沙投入、人工(机械)放淤投入和排沙入海投入等6个主要评价指标,提出了各个评价指标和综合评价函数的计算方法,并提出了黄河泥沙配置方案的综合评价方法。通过对12个黄河泥沙空间优化配置方案进行综合评价,建议了较优的配置方案。方案中各种配置方式平均配置沙量比例分别为:水库拦沙量41.0%、河口造陆沙量18.0%、深海输沙量17.8%、引水引沙量10.4%、人工(机械)放淤沙量6.9%、主河槽冲淤沙量3.8%、洪水淤滩沙量2.1%。

     

    Abstract: A framework is basically established for the evaluation of sedmient optmial allocation in them a instream of Yellow River.The framework is built on the systemic,hierarchical,representative,quantitative and com parable principles,and includes six evaluation parameters amiing at both technologic and economic subobjectives in the spatial optimization of sediment allocations.The procedure of calculating the six evaluation parameters is proposed.The synthetic evaluation function is presented.As the result,a method for comprehensive evaluation of sedmient optmia l allocations in the mainstream of Yellow River is determined.The method is used to evaluate 12 existing schemes of sediment optmial allocations in the Yellow River,and a preferable scheme is identified.The scheme suggests the optimal compositions of sediment allocations,which are 41.0% held in reservoirs,18.0% for land formation in estuaries,17.8% discharged into deep seas,10.4% consumed by irrigation,6.9% for siltation to beaches,3.8% for silting of mainstream,and 2.1% for silting flood plains.
