摘　　要：随着金沙江下游梯级水电站的相继建成投运及一大批水文泥沙观测站的建设,一方面河道水文泥沙情况较天然状况有较大改变,另一方面将产生海量的水文观测数据。这些数据的查询、分析、计算及直观展示对数据管理提出了很高要求。着重研究了河道断面数据管理及其可视化的实现方法,主要包括断面要素计算、断面套绘、深泓纵剖面变化图绘制、槽蓄及冲淤量计算等。该可视化系统为金沙江下游区域的泥沙水文资料的研究提供了一个有力工具。With the cascade hydropower stations being put into operation and construction of a batch of hydrological stations on Jinsha River, the fluvial condition has been changed greatly compared with natural environment, at the same time a large quantity of survey data is generated. The query, analysis as well as display of these data have put forward high requirements on data man- agement. We focus on river profile data management and its visualization methodology, including calculation of cross - section el- ement, plot of cross - section, longitudinal variation of talweg, channel storage as well as deposition - scouring value. The pres- ented visualization system provides a helpful tool for study of hydrological and sediment data on lower Jinsha River.
