摘　　要：随着GPS的快速发展,RTK测量技术也日益成熟,并逐步在测绘中得到应用。分析GPSRTK技术在第一次水利普查青海湖容积测量中的应用,就GPSRTK技术在水下地形测量中数据处理方法和野外测量优势进行探讨。在青海湖容积测量中的应用说明,RTK技术改变了水下地形测量的作业模式,真正实现高精度、高效率,减轻了劳动强度,经过不断发展和完善,RTK技术将改变测绘领域其他如控制测量、纵横断面测量、施工放样等的手段。With rapid development of GPS, RTK has reached a mature stage, and is gradually applied for survey. The essay introduces employment of RTK at lake volume measurement of Qinghai lake for the first national census for water, approaches a subject about data processing methods for underwater topographical survey and advantages of field survey. Its application illustrates that using RTK has already changed the way of underwater survey, realizing high precision and efficiency, and reducing labor intensity of work. Continuous development of RTK will change survey methods, such as control survey, vertical cross section measurement and construction lofting as well.
