摘要: 本文简要介绍了青藏高原长江河源地区冰川,冻土和地质构造对水系发育和河况的影响,初步分析了该地区河流的经流、洪水、枯水、水温和冰情的变化规律.文中着重阐明河流洪水形成的基本特征,并据观测资料和洪水调查资料,探讨了百年一遇洪峰流量的分布规律,该成果可供长江河源地区铁路,公路桥涵设计参照使用.

Abstract: This paper briefly describes the main characteristics of physical geographic conditions in the riverhead area of the Yangtze River, in the Qinghai-Xizang Plateau, and deals with the influences of glaciers,cryopedolcgical conditions and geological structures upon stream systems and river regimens.Some regularities of variations of runoff, flood, low water, water temperature and river freeze are involved in the paper.The basic features of flood generation can be analyzed on the basis of relevant physical geographic conditions in the area. According to observation data and flood investigations, an estimation of flood peak discharge with 100 year recurrences of the rivers in the area is presented for designing the railway and highway bridges.
