摘要
Abstract
The Morlet wavelet method is used for researching the discharge variation regularity of Yangtze River. Annual average discharge,annual maximum discharge and annual minimum discharge time series of Datong hydrological station from 1950 to 2012 are analyzed. Variation regularity and variation period of Datong hydrological station is obtained. The results show that the annual maximum discharge has increased by 5.43%,the minimum discharge has increased by 39.4%,the annual average discharge has reduced by 1.39%.关键词
