摘　　要：雅鲁藏布江是我国重要的水源地、水电能源基地和生物宝库,是我国实施西部大开发战略的重要区域。掌握雅鲁藏布江基础地理、水文信息,是开展雅鲁藏布江水资源开发和管理的重要基础环节和资料支撑。但目前,雅鲁藏布江下游河段河道资料,对该河段水资源开发形成了很大的短板困扰。此次测量填补了此区域没有河道勘测成果的空白。本文结合雅鲁藏布江下游河段河道地形及断面测量工作,阐述雅鲁藏布江下游河段测量使用的GNSS搭载单波束测深仪的应用及面临的困难,以及采取的安全措施,浅谈此次测量工作的经验及教训。The Yarlung Tsangpo River is an important water source, hydropower energy base and biological treasure house in China. It is also an important area for China to implement the western development strategy. Mastering the basic geographic and hydrological information of the Yarlung Tsangpo River is an important basic link and data support for the development and management of water resources of the Yarlung Tsangpo River. However, at present, the river channel data of the lower reaches of the Yarlung Tsangpo River has formed a great obstacle to the development of water re-sources in this reach. This survey fills the gap that there is no river survey result in this area. Combined with the topographic and cross-sectional survey of the lower reaches of the Yarlung Tsangpo River, this paper expounds the application and difficulties of the GNSS single beam bathymeter used in the survey of the lower reaches of the Yarlung Tsangpo River, as well as the safety measures taken, and discusses the experience and lessons of this survey.
