| 摘 要： | 利用db3小波分解和重构1965～2007年长江源沱沱河站、直门达站和黄河源吉迈站、唐乃亥站春汛期、夏讯期和枯水期流量数据,除沱沱河外,各站春汛期、夏汛期和枯水期流量皆呈下降趋势,各站流量下降速率依次为夏汛期＞春汛期＞枯水期.沱沱河站多年流量呈增加趋势,夏汛期变化速率依然高于春汛期.应用复Morlet小波分别分析上述4...

| Abstract: | By decomposing and reconstructing the runoff information from 1965 to 2007 of the hydrologic stations of Tuotuohe,Zhimenda in the source region of Changjiang River,and Jimai,Tangnaihai in the source region of Huanghe River with db3 wavelet,the runoff data of different hydrologic stations were analysized.The result shows that the runoff declines in spring flood season,summer flood season and dry season except for those in Tuotuohe.The order of declining flood/dry season is summer > spring > dry.While runoff ... |
