Abstract: In this paper, water area and storage capacity of Xin'anjiang reservoir were calculated using digital elevation model which was constructed based on terrain data of Xin'anjiang reservoir (2001 and 2011). Then, the changes of water area and corresponding storage capacity of Xin'anjiang reservoir were analyzed quantitatively in the year of 2001 and 2011. Finally, water level- capacity curve model of Xin'anjiang reservoir was checked, which could provide a new reference for the regulation of Xin'anjiang reservoir.

Key words: Xin'anjiang reservoir, aerial photogrammetry, storage capacity, water area, DEM

摘要： 采用航空摄影测量技术获得2001年和2011年新安江水库摄影水位以上的地形数据，通过构建DEM计算新安江水库水域面积和库容。从平面和立体两个不同的角度，分析了新安江水库2001年和2011年水域面积的变化与相应区域的库容变化。从平面上分析了水域面积变化，从立体上分析了库容变化，对水域和库容的变化都进行了定量分析与定位分析，校核了新安江水库现有的水位-库容曲线模型，为新安江水库调度提供了参考。
