By applying the theory of wavelet transformation and the 1919-1996 natural runoff records of Lanzhou hydrometric station, the runoff variation along the upper reaches of the Yellow River is studied. The periods of runoff and points of abrupt change at different time scales are analyzed. The wavelet variance verification indicates that the main periods of the runoff variation along the upper reaches of the Yellow River are 22, 15, 4 and 37 years respectively in order of importance. Basing on the main period of 22 years, we predict that runoff will be in the dry period from about 1996 to about 2007.

应用小波变换理论,采用兰州站1919~1996年共78年间天然径流资料,研究黄河上游河川径流变化规律,分析不同时间尺度下的周期及突变点.小波方差检验表明,黄河上游径流变化的主要周期是22年,其次是15年、4年和37年,以22年的主要周期预测黄河上游1996年后直到2007年前后径流将处于偏枯期。
