摘　　要：以2020年长江5号洪水为例,结合遥感与地理信息系统(GIS)技术,基于天空地协同的超标准洪水监测体系,研究并提出了超标准洪水淹没影响指标提取和淹没影响分析技术,并针对长江5号洪水过程,开展了三峡库区和上游重庆地区天空地协同监测及淹没影响分析技术的应用。结果表明:该技术能充分利用遥感和GIS技术实现对淹没影响区域的多维度决策支持,并在2020长江5号洪水影响分析实践中得到了检验,可为洪灾淹没影响快速分析提供技术支撑和应用示范。In this paper,the extraction of monitoring indicators of Exceeding-standard floods(ESF)and inundation analysis of ESF are investigated through the case study of Yangtze River’s No.5 flood in 2020.A systematized methodology is proposed to address this problem using the integrated approach of remote sensing(RS)and Geographical Information System(GIS),based on the Space-Air-Ground Integrated Monitoring Architecture on Exceeding-standard Floods(SAGIMAESF)[1].This methodology is applied in the prediction and assessment of No.5 flood inundation in TGP reservoir.The applied effects indicate that this methodology can be of good reference value for rapid flood inundation analysis.
