摘要
以黑龙江哈巴罗夫斯克站1897—2005年共109a年径流时间序列和1897—1985年共89a月径流时间序列为基础,应用累积距平法和Mann-Kendall法等,分析计算哈巴罗夫斯克站年径流丰枯特征及其阶段性、径流年内分配不均匀性、集中度。结果表明:哈巴罗夫斯克站径流连丰年、连枯年交替出现,径流年际变化阶段性明显;哈巴罗夫斯克站径流量年内分配不均匀,主要集中在夏秋两季,占全年的76.01%;20世纪60年代径流年内分配最为均匀,10年代最不均匀。
Based on a 109-year annual runoff time series from 1897 to 2005 and an 89-year monthly runoff time series from 1897 to 1985 at the Khabarovsk Station on the Heilongjiang River, the high and low flow variation characteristics and stages of the annual runoff, and the unevenness and concentration degree of the intra-annual runoff distribution were analyzed using the cumulative anomaly method, the Mann-Kendall method, and other methods. The results show the following ： （ 1 ） the continuous high flow year and continuous low flow year alternated at the Khabarovsk Station, and there existed distinct stages for the variation of the inter-annual runoff; （2） the intra-annual runoff at the Khabarovsk Station was unevenly accounted for 76.01% of the runoff of the whole year; and in the 1960s and most uneven in the 19lOs. distributed, and the runoff in summer and autumn （3） the intra-annual runoff distribution was most even
