| 摘 要： | 根据白龙江上游白云水文站1965-2010年46 a的月年实测径流资料,用径流的年际变化、年内各月占年径流的百分比、年内不均匀系数、集中度以及变化幅度等不同指标,分析研究了白龙江上游径流年际变化和年内分配的规律.研究表明:白龙江上游年径流量受气候变化和流域天保工程的实施,年际变化趋势逐步减小,径流重心位置基本未发生变化...

| Abstract: | In this paper,the characteristics of intra-annual variation and inter-annual distribution of runoff in the upper reaches of the Bailongjiang River were analyzed by using the monthly runoff data during the 46 years observed at the export control station,Baiyun Hydrologic Station.The analysis was conducted by using different indexes,including annual runoff variation,monthly runoff ratio,annual runoff inhomogeneity coefficient,runoff concentration ratio(or period) and changing amplitude.The research results sh... |
