中文摘要：【目的】研究海洋热量输送对南海叶绿素a(Chl-a)质量浓度的调控机制,为海洋生态系统对厄尔尼诺?南方涛动(ENSO)事件的响应预测、渔业资源评估及环境检测提供科学依据。【方法】利用Chl-a质量浓度、海表温度(SST)、热含量(OHC)、Ni?o3.4数据集,采用统计学方法分析ENSO不同事件下海洋热量输送对Chl-a质量浓度的差异化影响。【结果与结论】1998―2024年,南海Chl-a质量浓度由沿岸向深海递减。Chl-a质量浓度和SST呈负相关。在厄尔尼诺时期,南海北边界热量输出增多,东边界持续输入,南海北部、中部、东部和东南部海域的OHC降低;西南部热量输出减少,使西南部的OHC增加;经过6个月的滞后期SST整体提升,滞后3个月时,南海整个海盆的Chl-a质量浓度显著降低,而沿岸的Chl-a质量浓度增加。在拉尼娜时期,南海北边界热量输出降低,东边界持续输入,南海北部、中部、东部和东南部海域的OHC上升;西南部热量输出增强,使西南部的OHC降低;经过6个月的滞后期SST整体降低,滞后3个月时,南海整个海盆的Chl-a质量浓度显著增加,而沿岸的Chl-a质量浓度降低。

外文摘要：【Objective】This paper aims to investigate the regulatory mechanism of ocean heat transport on chlorophyll-a(Chl-a)mass concentration in the South China Sea(SCS),and provide a scientific basis for predicting marine ecosystem responses to El Ni?o-Southern Oscillation(ENSO)events,assessing fishery resources,and monitoring environmental conditions.【Method】Using Chl-a mass concentration,sea surface temperature(SST),heat content(OHC),and Ni?o3.4 data sets,statistical methods were employed to analyze the differential effects of ocean heat transport under different ENSO events on Chl-a mass concentration.【Results and Conclusions】From 1998 to 2024,Chl-a mass concentration in the SCS decreased from the coast to the deep sea.Chl-a mass concentration was negatively correlated with SST.During El Ni?o periods,the heat output from the northern boundary of the SCS increased,while the east boundary continuously input heat,resulting in the OHC in the northern,central,eastern,and southeastern areas of the SCS decreased.The heat output from the southwest decreased,causing an increase in OHC in the southwest.After a 6-month lag,SST increased overall,at a 3-months lag,the Chl-a mass concentration in the entire South China Sea basin significantly decreased,while the Chl-a mass concentration along the coast increased.During La Ni?a periods,the heat output from the northern boundary of the SCS decreased,while the east boundary continuously input heat,resulting in the OHC in the northern,central,eastern,and southeastern areas of the SCS increased.The heat output from the southwest increased,causing an decrease in OHC in the southwest.After a 6-month lag,SST decreased overall,at 3-month lag,the Chl-a mass concentration in the entire South China Sea basin significantly increased,while the Chl-a mass concentration along the coast decreased.
