摘　　要：通过卫星遥感影像对2021年南黄海海域绿潮的分布和发展进行了持续监测,发现3月底主要以马尾藻分布为主,后续马尾藻向北发展;5月中旬,南黄海中部海域监测到马尾藻分布;5月下旬,绿潮分布靠近江苏近岸,规模迅速扩大,主要以浒苔分布为主;6月19日达到峰值,随后绿潮覆盖面积下降,至8月25日完全消亡。绿潮规模在5月下旬进入暴发阶段,至6月中旬达到峰值。完整分析了南黄海海域2021年绿潮的发展与空间分布特征,可推动绿潮防控的研究与应用,为后续绿潮防控提供参考。The distribution and development of green tide in the South Yellow Sea in 2021 were monitored by satellite remote sensing images.It was found that Sargassum was the dominant species at the end of March,and then it developed northward.In mid-May,Scagassum was detected in the central area of the South Yellow Sea.In late May,the distribution of green tide was close to the coast of Jiangsu,and its scale expanded rapidly,mainly distributed by Enteromorpha prolifera.It reached its peak on June 19,followed by a decrease in the area covered by the green tide,which died out completely on August 25.The scale of green tide entered the outbreak stage in late May and reached its peak in mid-June.In this paper,the development and spatial distribution characteristics of green tide in 2021 in the South Yellow Sea area were analyzed completely,which can promote the research and application of green tide prevention and control,and provide a reference for subsequent green tide prevention and control.
