摘　　要：2022年6—8月,珠江流域连续出现强降雨,共发生8次编号洪水,防汛形势严峻复杂。在珠江流域防汛关键期,基于国产高分三号、海丝一号、欧空局哨兵一号雷达卫星影像,结合国产高分一号、吉林一号光学卫星影像,开展了洪涝灾害重点区域应急遥感监测评估,对潖江蓄滞洪区的水体面积变化及围的启用情况、洪涝灾害重点区域的水体面积变化情况进行遥感动态监测与分析。分析结果显示,6月23日北江流域潖江蓄滞洪区共启用5个围,水体面积达到最大,为39.51 km^(2);英德市县(区)及周边乡(镇)水体面积在23日达最大,遥感监测范围内为143.16 km^(2);西江干流梧州段水体面积在6月19日达最大,桂江支流思良江区域淹没情况较为严重。From June to August 2022, the Pearl River Basin suffered from continuous heavy rainfall and a total of eight numbered floods, presenting a severe and complicated flood control situation. During the critical period of flood control in the Pearl River basin, the Remote Sensing Technology Application Center of the Ministry of Water Resources carried out emergency remote sensing monitoring and assessment of key flood disaster areas based on the radar satellite images of China’s GF-3, Hisea-1 and ESA Sentinel-1, and combined with the optical satellite images of China’s GF-1 and Jilin-1. This paper carried out remote sensing dynamic monitoring and analysis on the change of water body area in Pajiang flood detention area, the opening of the polder, and the change of water body area in key flood disaster areas. The monitoring results show that on June 23, a total of 5 polder were used in the Pajiang flood detention area in the Beijiang River basin,and the water body area reached the maximum as 39.51 km^(2). The water body area of counties and surrounding townships of Yingde City also reached the maximum on the June 23, with a remote sensing monitoring area of 143.16 km^(2). The water body area of the Wuzhou section of the Xijiang River reached its maximum on June 19, and the area of the Siliang River, a tributary of the Guijiang River, was severely inundated.
