中文摘要：选取南海北部珊瑚带宽-SST分别与甘肃万象洞WX42B石笋和贵州董哥洞DA石笋的δ^(18)O记录在不同时段进行对比,揭示了南海北部SST变化与夏季风强度的关联。结果显示:在年际―年代际尺度上,南海北部珊瑚带宽-SST与石笋δ^(18)O记录的夏季风强度存在负相关关系:南海北部SST升高,石笋δ^(18)O偏重,夏季风强度减弱;反之亦然。南海北部器测SST与万象洞WX42B石笋δ^(18)O记录的对比也证实了这一关系的存在。ENSO活动影响着季风区的降雨量,控制着南海北部的SST变化。ENSO的存在可能是造成这种负相关关系的直接原因。由于ENSO活动与季风区降雨量的关系存在区域性差异,南海北部SST与局部地区夏季风强度之间的关系仍需进一步的研究。

外文摘要：Based on comparison of band-SST of Porites from Northern South China Sea and δ^（18）O records from Wanxiang Cave, Gansu province and Dongge Cave, Guizhou province, this paper revealed the relationship between SST of the Northern South China Sea and strength of East Asian Summer Monsoon（EASM）. On inter-annual and inter-decadal time scale, there is a negative correlation between SST of the Northern South China Sea and the strength of EASM. When SST rises, the value of stable oxygen isotope becomes heavier and the strength of EASM weakens, and vice versa. The comparison of instrument-measured SST and δ^（18）O record from stalagmite WX42 B, Wanxiang Cave verified the relationship. ENSO influences the rainfall of the monsoon region and controls the SST of the Northern South China Sea. ENSO may directly result in the negative correlation between SST of the Northern South China Sea and the strength of EASM. But the relationship between ENSO and rainfall of the monsoon region is complicated, the relationship between SST of the Northern South China Sea and local monsoon regions still needs further study.
