摘　　要：使用常规方法更新水库地形图无法满足水库调度、泥沙监测和洪水预报的需要,等高线等比降化算法是基于断面实测地形数据更新水库等高线的计算方法,它通过对原有等高线的修正、更新来达到更新水库地形图的目的。小浪底水库的应用结果表明:使用该方法更新水库地形图,可以及时掌握水库的冲淤分布,全面了解水库地形变化及库容变化情况。Using conventional methods to update topographic map cannot meet the needs of reservoir regulation,sediment monitoring and flood forecasting. The calculation method of topographic map updating based on the section measurement data introduced in this paper can modify the original contour and update the topographic map. Through the application in Xiaolangdi Reservoir,this method can obtain the information of the scouring and depositing distribution and the changes of terrain and reservoir capacity.
