This paper analyzes river system and river automatic adjustment behavior.The theory hypothesis of river automatic adjustment behavior for the cause of alluvial river pattern and the discriminant of sediment-laden flow system and river bed form system of river pattern are proposed.Taking Liuhe segment in the downstream of the Yellow River and Jianghan river segment for an example,the established theory and river pattern discriminant are validated by the fuzzy equivalent matrix cluster method.The results show that the established theory and river pattern discriminant are correct;the influence of river sediment-laden flow system and river bed form system on formation of river pattern is equivalent.
