摘 要:准确获取径流量的时间序列特征,有助于水资源的开发利用和水利水电工程的规划运用。采用趋势分析法、Mann-Kendall突变分析法、小波分析法对松花江流域依兰站和佳木斯站1972-2010年间的年径流量时间序列进行分析。结果表明:松花江依兰-佳木斯段的年径流量近40年来总体呈微弱下降趋势,佳木斯站年径流量下降趋势强于依兰站年径流量下降趋势,且均存在较明显的周期性变化规律,即存在以18、8和5a这3个时段为主周期的波动状态。整个研究河段年径流量时间突变明显,依兰站在1973年之前为上升趋势,1974-1983年为下降趋势,1984-2004年为上升趋势,2004年之后为下降趋势;佳木斯站在1973年之前为上升趋势,1974-1984年为下降趋势,1985-2002年为上升趋势,2002年之后为下降趋势;而且两站的年径流量突变趋势较为同步。小波预测结果表明2010以后,年径流量有增加趋势。To catch the characteristics of time serials of runoff in the main steam of the Songhua River is conducive to the rational development of water resources and programming of water conservancy and hydropower engineering.A trend analysis method,MannKendall abrupt change analysis,and wavelet analysis are used to analyze the time analysis of runoff in the main stream of the Songhua River based on runoff observed data of the Yilan and Jiamusi from 1972 to 2010.The results show that there are three main periods of 18 years,8years and 5years for annual runoff series.For the whole series of runoff in the main stream of the Songhua River,there are the following variation trends.In Yilan there was an upward trend from the year 1972 to 1973,then there was a downward trend from the year 1974 to 1983,after that there was an upward trend from the year 1984 to 2004,and then there was a downward trend of annual precipitation series.In Jiamusi there was an upward trend from the year 1972 to 1973,then there was a downward trend from the year 1974 to 1984,after that time there was an upward trend from the year 1985 to 2002,and then there was a downward trend of annual precipitation series.
关 键 词:时间序列分析 径流量 趋势分析法 Mann-Kendal突变分析法 小波分析
