中文摘要	本文建立的冲积河流河型成因的输沙平衡程度概念认为,不同冲积河流河型形成的根本原因在于其输沙平衡程度的不同。根据强平衡输沙概念,建立了冲积河流稳定程度公式。利用黄河、渭河和汉江部分资料进行的初步计算表明,根据河型成因的输沙平衡程度概念,基于冲积河流稳定程度公式,采用模糊聚类方法,可以建立一套完整的河型分类与判别的模糊聚类计算方法。; The analysis presented in this paper indicates that there is a correspondence relationship between the equilibrium degree of sediment transport and the complete channel characteristics.The classification and discrimination of river types are based on the complete channel characteristics,the formation of river types is based on the equilibrium degree of sediment transport.The channel patterns formed in alluvial rivers lie in the variable equilibrium degrees of sediment transport.A dimensionless parameter is derived based on theoretical formulas that describe the flow,sediment and riverbed conditions by strong equilibrium sediment transport.This dimensionless parameter is viewed as the channel stability parameter,based on which a channel pattern discrimination procedure is developed.Test of the procedure in the lower Yellow River and the Wei river indicates that the computation results are consistent with the field observations and the fuzzy cluster method is applicable in practical use.; 中荷战略科学联盟计划项目(2004CB720400); 国家自然科学创新研究群体科学基金资助项目(50221903)
