摘　　要：河相关系的研究旨在寻求河床形态和流域水文、动力因子间的定量关系。在介绍国内外平原冲积河流及潮汐河口河相关系研究进展的基础上,对基于水文统计的经验分析法、量纲分析法、河床最小活动性假说、水流最小能耗率极值假说以及仙农熵理论等5种代表性的河相关系研究方法进行了对比分析,阐述了5种方法的适用性。同时,进一步指出了目前研究河相关系存在的问题和困难。The goal of fluvial facies relation research is to build a quantitative relationship between riverbed morphology and basin hydrology, hydrodynamic factors. We summarize the recent research advances on fluvial facies relation of plain alluvial riv- ers and tidal estuaries. Further, we conduct comparative study on five fluvial facies relation research methods, including empiri- cal method based on hydrological statistics, dimensional analysis method, hypothesis of minimum activity of riverbed, hypothesis of extreme value of the minimum energy dissipation rate, and Shannon entropy theory. The problems and difficulties of present fluvial facies relation are analyzed and the applicability of these five methods is evaluated.
