| 摘 要： | 河流径流量变化是对区域气候和下垫面变化的综合反映，了解和认知其变化对流域资源开发具有重要意义。根据松花江哈尔滨水文站1900-2005 年径流量资料,采用距平累积和M-K检验方法分析了哈尔滨站近百年来径流量变化趋势。结果表明：哈尔滨站8、9月份M-K检验分别达到0.006和0.034的置信度水平，但年径流量没有表现出显著趋势性特征。1920年开始哈尔滨站径流量开始减少，1997年开始径流量由减少变为增加趋势。哈尔滨站径流量年际变化存在明显的阶段性，1900-1907年、1915-1928年、1975-1980年和1999-2005年为4个枯水段；1970-1974年为平水段；1908-1914年、1929-1969年和1981-1998年为3个丰水段。

| Abstract: | The runoff variation is a comprehensive reflection to the changes of regional climate and the underlying surface of the earth. Understanding and awareness of its change is of great significance for the development of river resource. Based on 1900 -2005 runoff information of Harbin Station of the Songhua River, accumulation deviation from average and analysis of the M-K test are used to analyze trend of runoff in Harbin Station in the past century. The results showed that: although Harbin Station M-K tests in August and September were 0. 006 and 0. 034 of confidence, there is no significant tendency to annual runoff. The runoff of Harbin Station began to reduce in 1920, and started an upward trend from the decline in 1997. Furthermore, annual runoff in Harbin Station had significant changes in the following stages: 1900 - 1907, 1915 - 1928, 1975 -1980 and 1999 - 2005 as four dry stages, 1970 - 1974 as the medium water stage, and 1908 -1914, 1929 - 1969 and 1981 - 1998 as the three wet stages. |
