1984-2023年华南三省(区)近岸海域赤潮时空特征研究
Spatiotemporal characteristics of red tides in coastal regions of three provinces(regions)of South China from 1984 to 2023
摘要
Abstract
The records of historical red tide in coastal regions of three provinces(regions)of South China from 1984 to 2023 are collected to analyze their spatiotemporal characteristics using geographic information system(GIS)technology.The results show that the frequency of red tide events exhibits an overall upward trend,while the annual cumulative area fluctuates significantly.Red tides occur in all seasons,with high occurrence probability in the season of spring(January to May)and in the month of April.Most of the red tide events are small in size and approximately 92%of them occur in the Guangdong coastal seas,such as the Pearl River Estuary,Mirs Bay,Zhanjiang,Daya Bay,Shanwei,Chaoshan and other inner bays.Noctiluca scintillans is the first dominant algae species in the South China Sea coastal waters,mainly existing in the waters of Mirs Bay in spring,autumn and winter.The four most frequently observed dominant algal species are Noctiluca scintillans,Phaeocystis globosa,Akashiwo sanguinea and Skeletonema costatum.关键词
