冰凌输砂是河流泥沙运动的一部分.凡结冰河流都有冰凌输沙现象.本文是根据黑龙江省北部河流观测到的冰凌输砂资料,说明冰凌输砂的存在、形成、分类和研究冰凌输砂的意义. 北方河流每年都经历秋季结冰流凌到冻结盖面冰;春季解冰流凌到畅流两个时期,即冰期和畅流期.随着河流的地理位置和季节变化,又出现不同机理的冰情现象.伴随 Icing is a part of the river sediment movement.All icing rivers have ice sediment transport.This paper is based on the ice in the northern part of Heilongjiang Province, the observed data on the ice, indicating the existence of ice sand, forming, classification and research ice The significance of sand transport.The northern rivers experience the autumn icing flow every year to freeze the cover ice; spring ice flow Lingling two periods of smooth flow, namely the ice period and the smooth flow of time.With the river’s geographical location and seasonal changes, There are different mechanisms of ice phenomenon
