摘　　要：基于快捷精准计算水库库容,并与原始库容对比分析库容淤积的目的,使用Global Mapper软件的库容计算和DEM叠加分析功能,通过水库库容复核工程实例进行应用试验,结果表明使用Global Mapper计算库容的结果精度与等高线法的库容结果相当,计算高效、结果可靠,DEM叠加分析成果可以直观展示库容淤积分布,有助于为管理单位冲淤冲沙提供决策。Based on the fast and accurate calculation of reservoir capacity,and the purpose of comparing and analyzing reservoir capacity siltation with the original capacity,the Global Mapper software's capacity calculation and DEM overlay analysis functions were used to conduct application experiments on reservoir capacity review engineering examples.The results showed that the accuracy of using Global Mapper to calculate reservoir capacity was comparable to that of contour method,with high efficiency and reliability,the results of DEM overlay analysis can visually display the distribution of reservoir capacity and sedimentation,which helps to provide decision-making for management units in erosion,sedimentation,and sand erosion.
