本文选取位于西菲律宾海本哈姆高原上的岩心MD3050,对沉积物中的浮游有孔虫生物群进行系统地鉴定和统计。利用FP-12E浮游有孔虫的转换函数(Thompson,1981)与现代类比技术(MAT)恢复古温度;利用时间序列分析方法研究古环境要素演化的周期性和短期的突变事件,探讨黑潮源区及低纬太平洋地区古环境记录变动的驱动机制。最终发现岁差驱动的低纬地区太阳辐射变动对于这一区域夏季SST的变动起到主要的驱动作用,而其作用媒介很可能是东亚夏季风。冬季SST则在偏心率周期上和几个与岁差驱动有关的周期上都明显相关,意味着冬季SST的变动受到高纬度和低纬度因素的共同制约,冰期中强化的东亚冬季风对于SST存在明显的影响。

This paper chooses the core of MD3050 on the Hamm plateau in West Philippine Sea, to appraisal and statistics the biota of planktonic foraminifera on the sediment systematically. Using the transfer function of planktonic foraminifera FP-12E (Thompson, 1981) and the modern analog technique (MAT) to restore the ancient temperature; Using the method of time series analysis to research the cyclical evolution of paleo-environment factors and short-term events of the mutation, to explore the drive mechanism of the source of the Kuroshio and changes of low-latitude Pacific region recorded paleo-environment. Found the precession-driven changes of solar radiation in the low latitude is the main reason of SST changes in the summer, while the role of the media is likely to be the East Asian summer monsoon. In winter, SST are significantly related to eccentricity cycle and a few with the precession-driven cycles changes,it means the changes of SST in winter were restricted by higher and lower l
