摘　　要：水库蓄水量研究对于合理保护和利用水资源具有重要的指导意义.针对水库蓄水量估算研究现状和不足,使用星载雷达高度计(RA)提取水库的遥测水位,利用星载多光谱成像仪(MSI)和星载合成孔径雷达(SAR)提取水库的水域面积,基于数据同化技术建立了多源遥感水库蓄水量估算模型,并开发了一款多源遥感水库蓄水量估算系统.该系统可以无接触地获取遥测水位和水域面积并估算蓄水量,具有稳定性、通用性等特点,有望应用于防汛抗旱、水库调度等领域,为管理部门科学化、高效化管理水库提供技术支撑.The study of reservoir storage capacity can provide a valuable guide to the rational protection and utilization of water resources.With regard to the current situation and shortcomings of the estimation of reservoir storage,the remotely measured water levels of a reservoir are extracted by a Radar Altimeter(RA),and the surface water area is collected with a Multi-Spectral Instrument(MSI)and a Synthetic Aperture Radar(SAR).Then a reservoir storage estimation model based on data assimilation of multi-source remote sensing is established.Finally,a reservoir storage estimation system based on multi-source remote sensing data is developed,which can obtain remotely measured water levels and water area and estimate water storage capacity without contact.Experimental results prove that this system has stability and versatility.It is expected to be applied to flood control,drought resistance,reservoir dispatching and other fields to provide a technical support for the scientific and efficient management of reservoirs.
