摘要： 四棵树河近20年发生14次突发性洪水, 洪水出现在冬季(11月22日-1月22日), 洪峰陡涨陡落, 洪水流量大大超过夏季最大洪峰.其成因主要是由河冰堵塞谷地, 形成暂时性湖泊溃泄所致, 洪水是多源地形成, 沿四棵树河主谷各有数处易形成河冰湖.河冰湖的形成与河谷地形条件、气温变化相关。

Abstract: 14 outburst floods had been occurred in Si Keshu River since 1970. The floods occurred in winter ( 22 November to 22 . December). The flood Peak with rising and dropping steeply was bigger than that of occurred in summer. The outburst floods may be caused by the water releasing of the river ice-dammed lake in middle of the river. There were several places where can be easy formed Ice-dammed lake in Si Keshu River Valley. The formation of the ice-dammed lake was related to both the river Landform and temperature fluctuation.
