中文摘要:

周期分析是水文序列变化特征研究中的一项重要内容。根据漳卫南运河流域1956-2005年间的年降水量数据以及元村、淇门和临清3个站点的年径流量数据,对水文序列进行趋势分析,采用Morlet小波进行周期分析。研究结果表明:自1956年漳卫南运河流域的年降水量和年径流量均呈现下降趋势;不同时间尺度具有不同的降水和径流结构;年降水量变化的主周期为准6a、12a和准16a;元村、淇门和临清站年径流量具有两个相同的主周期,分别为准5a和准16a。

英文摘要:

Analysis on periodic oscillation is the basic content of hydrologic research.In this paper,according to the annual precipitation in the Zhangweinan canal basin and runoff at Yuancun,Qimen and Linqing gauging stations from 1956 to 2005 were analyzed.Results showed that the annual precipitation and runoff have been a declination trend since 1956.There are different structure of precipitation and runoff at different temporal scale.The main cycles of precipitation was 6,12 and 16a,while the annual runoff in Yua...
