摘　　要：根据河型成因的输沙平衡程度理论假说和水沙项输沙平衡程度公式,用水沙项数作为河型控制的控制指标量,以花园口到夹河滩河段为例对控制指标量取值,采用模糊等价矩阵聚类方法对黄河下游花夹河段河型控制结果进行验算。冲积河流河型控制的模糊聚类方法在黄河下游花夹河段的应用结果表明,在水沙项数可以控制的条件下,河型是可以得到控制的。Based on the sediment transport equilibrium degree theory and the equation of relational sediment transport equilibrium degree of water and sediment items,the values of water and sediment items are used in river pattern control.Taking the Huajia reach in the Lower Yellow River as an example,the values of water and sediment items are established and using natural fuzzy equivalence matrix clustering methods the river pattern control results of Huajia reach in the Lower Yellow River are verified.Verification results show that if the value of water and sediment items can be controlled,the river pattern can be controlled.
