中文摘要：
用全谱直读ICP-AES技术测定了海南岛东部（琼东）沿岸上升流区域滨珊瑚1906—1996年的Sr／Ca比值。结果显示珊瑚Sr／Ca比值重建的琼东海域的夏季海表温度偏低，强烈地受到东亚夏季风引起沿岸冷上升流的影响。结合西沙海域的滨珊瑚海表温度记录，首次重建了1906～1993年琼东沿岸风生上升流的强度指数变化序列。结果表明琼东上升流于1906～1993期间整体呈加强趋势，并具显著的年代际波动特征，同全球趋暖密切相关。此外，重建的上升流强度指数序列还揭示了大尺度环流——厄尔尼诺一南方涛动对琼东上升流强度变化的制约。
英文摘要：
Inductively coupled plasma atomic emission spectrometer （ICP-AES） were used to reconstruct a highresolution Sr/Ca-SST sequence （1906 - 1996） extracted from a modem massive Porites coral located at Boao of the northern South China Sea （SCS） . The reconstructed summer sea surface temperature （SST） is abnormally low, which is caused by summer coastal upwelling induced by summer monsoon. The 1906 - 1993 summer reconstructed SST sequence from the Boao waters were combined with another reconstructed SST sequence from the Xisha water, which is beyond the upwelling region to develop a summer coastal upwelling intensity sequence （UIS）. This reconstructed UIS shows a general strengthening trend in summer upwelling from 1906 to 1993 with significant fluctuation on interannual and decadal scales, which is consistent with the global warming in the 20th century. In addition this reconstructed UIS has also been constrained by the global event of the E1 Nino/southern Oscillation （ENSO）.
