摘要: 在现代冰川区,常有冰川洪水暴发,影响国家建设。对其加以研究,对于山区经济建设是十分必要的。据现有资料,我国的冰川洪水主要发生在新疆的西昆仑山、喀喇昆仑山及中国天山西部地区,藏南地区也频繁发生。根据其成因可分成两种类型:冰湖溃决型和冰川融水型。

Abstract: Some characteristics of glacial floods were analysed and discussed in this paper taking the rivers in Xinjiang as example. There are great differences between floods from glacial advance and those from glacial ablation. In general the former is not directly related with meteorological factors.However, the latter is a result of glacial ablation in hot summer season and closely related with the air temperature in the glacial ablation zone at the same altitude.The regression coefficient of glacial outburst flood is much larger than the regression coefficient of glacial melting flood.
