摘要
利用遥感卫片和航片资料查清了西藏年楚河上游冰川终碛湖的数量、大小和分布，并对其中最大的３个冰湖进行了分析，确认其中的白湖为一典型危险冰湖，只要有合适的气候条件就可能发生溃决。通过冰湖实地考察，验证了室内分析成果，补充收集计算所需的资料，采用美国天气局的ＢＲＥＡＣＨ模型和计算机程序。
By means of satellite remote sensing images and aerial photos, the number, scale and distribution of moraine-dammed lakes in the headwaters of the Nianchu River are investigated. Three large lakes among them were analysed. The Bai Lake was recognized to be a typical dangerous lake that would burst in a favorable climatic condition. Field investigation was carried out to collect the necessary data and to verify the results analysed in doors. Outburst flood of the Bai Lake was estimated with USWB BREACH model and computer program.
