多源时相遥感影像数据耦合的水库库容曲线重构

遥感技术为库容曲线的重构带来了新思路，但仍存在多源遥感影像数据难以直接应用、水库批量面积提取效率低等问题，难以形成一套系统化、流程化的方法进行广泛应用。基于此，本文提出了多源时相遥感影像数据耦合的库容曲线重构方法，并重构了深圳市径心水库的水位-库容关系曲线。试验证明，重构后的库容曲线常水位区间的库容曲线偏离率在4.23%~11.5%之间，能够为径心水库的调度管理提供参考，同时对全国库容曲线无法及时重构的水库具有参考意义。

Reconstruction of reservoir capacity curve by coupling multi-source time-phase remote sensing image data

Remote sensing technology brings new ideas for reservoir capacity curve reconstruction, but there are still problems such as the difficulty of direct application of multi-source remote sensing image data and low efficiency of reservoir batch area extraction, which make it difficult to form a systematic and process-oriented method for wide application. In view of this, this paper proposes a reservoir capacity curve reconstruction method coupled with multi-source time-phase remote sensing image data. The water level-volume relationship curve of Shenzhen Jingxin reservoir is reconstructed by this method. The experiments prove that the deviation rate of the reconstructed reservoir capacity curve is about 4.23%~11.5% in the range of normal water level, which can provide reference for the scheduling management of Jingxin reservoir. At the same time, it has reference significance for reservoirs in the country where the reservoir capacity curve cannot be reconstructed in time.
