摘　　要：基于DEM和“填充法”理念提出库容曲线计算方法,并编写MATLAB计算程序,一次性得出库容曲线全部数值。以七盏灯水库库容曲线计算为例,迅速地得到七盏灯水库库底至坝顶高程段、水位间隔为0.1m的库容曲线。该方法即方便快捷,又具有较高的计算精度,这将非常有利于水库规划设计和管理调度。Based on the concept of DEM and"filling method",a calculation method of storage capacity curve is proposed,and a MATLAB calculation program is written to obtain all the values of the storage capacity curve at one time.Taking the calculation of the storage capacity curve of Qizhandeng Reservoir as an example,the storage capacity curve of Qizhandeng Reservoir from the bottom to the top of the dam with a water level interval of 0.1m is quickly obtained.This method is not only convenient and fast,but also has high calculation accuracy,which will be very beneficial to reservoir planning and design and management and scheduling.
