合理地编制我国河流冰情的分类、名称、定义和图象,是发展河流冰情观测研究的一项基础工作。对此,我国早在五十年代就进行了大量工作,1955年在制定《水文测站暂行规范》时,确定了29种冰情名称、定义,同时规定了25种冰情图例。1962年编制《水文测验暂行规范》(冰凌观测)时,又进一步按冰情出现大致顺序,确定了34种冰情的名称、定义和
The reasonable preparation of the classification, name, definition and image of river ice conditions in our country is a basic work for the development of river ice condition observation research. In response, a great deal of work was carried out in our country in the 1950s.
