【摘要】 针对在洪水相似性研究中选择洪水指标过多会增加计算的复杂性以及信息重叠而导致计算结果失真等问题,提出了基于主成分分析的洪水相似性研究方法,将原洪水指标综合为少数几个不相关的主成分,再根据各场洪水的主成分进行洪水相似性分析。计算实例结果表明,该方法切实可行。更多还原

【Abstract】 In study the similarity of floods,choosing too many indexes may increase the computational complexity and overlapped information can lead to the distorted results.This paper proposes the method based on the principal components analysis to study the similarity of floods,which integrates the flood indexes into few number of uncorrelated principal components and then analyses the similarity of floods.The instance simulated results demonstrate the method is feasible.更多还原
