%X On the basis of analysis of the properties of hydrologic data, a new method, or two-stage-sequential method was developed to study the moving laws of river runoff. It absorbed the thoughts of hierachical clustering theory and formal system theory and multistage decision. The clue and calculating stages of this method have been introuced in detail in the paper, and taking Hong Shan Ju station of Manas River at the north slope of Tian Shan Mountains of Xinjiang Uygur Zizhiqu as an example. A group of indexes which reflect the annual moving laws of river runoff can be gained when this new method is applied. The concepts, such as characteristic period and characteristic degree, dominant period and dominant degree, etc., which are used in the method, are with explicit meaning and practical significance. The property of the indexes is good, and can be correctly comprehened from the point of the cause of runoff formation and runoff process. So two-stage-sequential method is a good method to study the moving laws of river runoff.
