黄河下游河型分类与判别模式研究

利用黄河下游11年资料的计算表明，本文在前人研究成果的基础上，根据泥沙运动基本理论、河床演变基本原理以及河流输沙强平衡概念建立的，以实用冲积河流稳定程度公式为理论和计算依据，由模糊聚类分析和判别分析方法构成的黄河下游河型分类与判别模式，可以为小浪底水库运用后黄河下游河型的分类与判别提供有力的理论依据和具体的计算方法，同时，也对其它冲积河流河型的分类与判别有一定的借鉴作用。

Classification and discrimination of channel patterns in the Lower Yellow River

In this paper,a method for the classification and discrimination of channel patterns for the Lower Yellow River was developed by using fuzzy cluster and discrimination analysis.The calculations were carried out based on a stability function that was derived from theoretical formulations of mechanics of sediment transport,fluvial processes,and strong equilibrium sediment transport for alluvial rivers.The calculated results using 11 years' data of the Lower Yellow River indicate that the proposed method can be used for the analysis and prediction of channel patterns in the Lower Yellow River after the use of Xiaolangdi reservoir.Moreover,the proposed method is of importance for the classification and discrimination of channel patterns of other alluvial rivers.
