摘要: 河川径流变化规律包括两方面:径流年内分配和径流的年际变化。主要研究径流随时间变化而出现的径流量分配特征、变化幅度、循环变化的特点、运动周期等。并用一些含意明确、简单的指标予以定量描述。

Abstract: 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.

Key words: Two-Stage-Sequential, Characteristic period, Dominant period, Cluster analysis, Multistage decision, Coefficient of annual difference
