黄河下游游荡河型与弯曲河型之间的关系研究

分析了黄河下游的河型分类,计算并统计了黄河下游冲淤标准化输沙平衡数,采用集合数学方法,研究了弯曲河型和游荡河型的关系。研究表明,在冲淤标准化输沙平衡程度数方面,弯曲河型是游荡型的真子集,游荡河型包含弯曲河型,弯曲河型与游荡河型的重叠部分建议归为弯曲河型,游荡河型比弯曲河型多了些数值较大的冲淤标准化输沙平衡程度数。

Research on Relationship Between Meandering River and Wandering River of Lower Yellow River

By analyzing the river classification of lower Yellow River,doing some calculation and statistics of alluvial standardized equilibrium degree of sediment transport and using set mathematics method,this paper researches the relationship between meandering river and wandering river.The research shows that meandering river is a proper subset of wandering and wandering river contains meandering river in alluvial standardized equilibrium degree of sediment transport.The overlap section of meandering and wandering river is suggested to be the part of meandering river.Wandering river has more big values of alluvial standardized equilibrium degree of sediment transport than meandering river.
