摘要
Abstract
When red tides occur,they not only cause serious harm to marine water bodies,marine organisms,fisheries,etc.,but also threaten human health through the food chain.An analysis is conductedthrough MODIS remote sensing images,the OCCSW component is used to calculate nFLH for red tide monitoring and verification in SeaDas.A comprehensive analysis is conducted on 33 red tide disasters that occurred in the coastal areas of Fujian Province from 2017 to 2021.The species,spatiotemporal distribution characteristics,and evolution patterns of red tide organisms in the coastal areas of Fujian Province are systematically analyzed.The results indicate that the duration of red tide from 2017 to 2021 is 173 days,affecting a total area of 307.74 square kilometers.The summary of the spatiotemporal distribution characteristics of Fujian Province in the past five years can provide reference for red tide monitoring and warning,disaster prevention and mitigation.关键词
