| 摘 要： | 利用1951-2000年水文、气象资料,在对黑龙江、松花江、嫩江发生的特大冰坝的年份监测中分析发现,冰坝发生大多在二江同时发生,个别年份有三江同时发生,并有群发特点。冰坝发生前,秋季降水多,河槽蓄水量多,河流水位高;冬季降雪多、气温低;春季开江期,有明显的降水和升温过程,是冰坝的形成和凌汛发生的重要原因。并且分析冰坝发生前期高空环流形势特点,依此研制了冰坝凌汛预报方法。

| Abstract: | Using hydrometeorological data observed from 1951 to 2000,the analysis of especially great ice jam in the Heilong River,Songhua River and Nenjiang River indicates that the ice jam occurs at same time in two rives frequently and in three rivers at times.Ample precipitation,large water storage in riverbed and high water level in river in Aulumn,abundant snowfall and lower temperature in winter and abvious precipitation and temperature rising in spring are important conditions to form ice jam and ice run.Circu... |
