摘　　要：不同类型的遥感数据各有其特点和优势,雷达数据具有全天时、全天候、高分辨率、全极化、多模式的观测优点,高光谱数据影像具有高空间分辨率和丰富的光谱信息。本研究综合利用GF-3雷达数据与珠海一号高光谱数据,对河南省丁店水库“7·20”特大暴雨进行监测分析,基于不同的水体提取方法对比实验,进行相关洪涝灾害分析。结果表明:1)GF-3雷达数据选用阈值分割法水体提取效果最好,珠海一号高光谱数据选用SBI法提取效果最佳;2)洪涝淹没区域中耕地受灾影响最严重。本研究可为河南省提供洪涝灾情信息,为丁店水库防灾减灾提供决策支持。Different types of remote sensing data have their own characteristics and advantages.RADAR data has the advantages of all-day,all-weather,high-resolution,full-polarization,and multi-mode observation,while hyperspectral data images have high spatial resolution and rich spectral information.This study comprehensively uses GF-3 RADAR data and Zhuhai-1 hyperspectral data to systematically monitor the“7·20”heavy rain around Dingdian Reservoir in Henan province,compares the different water body extraction methods,and analyzes the flood disaster of Dingdian Reservoir.1)The threshold segmentation method was used for GF-3 RADAR data to achieve the best water extraction effect,while the SBI method was used for Zhuhai-1 hyperspectral data to achieve the best extraction effect;2)The farmland in the flooded areas is most severely affected by the disaster.This study can provide flood disaster information for Henan province and provide decision-making support for disaster prevention and reduction of Dingdian Reservoir.
