摘要：

基于物理-生态耦合数值模型对2019年5月发生在福州连江黄岐半岛附近海域的赤潮事件进行研究，采用时空分析和叶绿素变化率方程诊断的方法，对该赤潮事件的形成过程和成因进行分析。结果表明：冷空气减弱造成的垂向层化和闽江口附近海域的离岸流输运共同作用，促进了此次赤潮的发生。

Based on a coupled physical-ecological numerical model, the formation processes and causes of the red tide event occurred near the coast of Huangqi peninsula of Fuzhou in May 2019 is analyzed using temporal-spatial analysis and diagnosis of chlorophyll change rate equation. The results show that the vertical stratification caused by the weakening of cold air and the offshore transport near the Minjiang estuary contribute to the occurrence of the red tide event.
