| 摘 要： | 利用紫坪铺水文站1966-2002年实测月径流资料，对岷江中上游径流时间序列分4个季节进行小波分析．由此发现，岷江中上游径流时间序列具有多个时间尺度的周期变化特征．四个季节径流量序列分别以主周期为16a，2．5a，1la，18．5a的振荡能量最为强大，径流量的主周期主要分布在较小的时间尺度上．

| Abstract: | By use of the actual monthly run-off data kept by Zipingpu hydrometricalstation, a wavelet analysis is made for the time series of the upstream run-off in the Minjiang River by season. The results show a periodical change in terms of a few dimensions conc |
