摘要:
本文系统性地总结了第四纪黑潮源区沉积物的源-汇过程、主要控制因素及其碳循环效应方面的最新研究进展。基于不同学科的综合性指标研究结果一致表明:黑潮源区的碎屑沉积物主要来源于附近的吕宋岛和大陆架及远端的亚洲东部沙漠。在轨道、千年和百年等不同时间尺度上两者对研究区的物质输入主要与海平面高度和东亚季风强度相关,并最终受控于高、低纬过程的双重驱动。而人类活动对黑潮源区的影响则出现于距今2100 a。上述陆源物质对研究区的输入过程与古海洋生物生产力、海底有机碳埋藏通量和大气二氧化碳浓度间也有着良好的协变性,表明黑潮源区的沉积物源-汇过程对全球碳循环起着重要的调节作用。上述研究工作可以为更好地预测未来气候环境的变化趋势提供关键低纬度海区的区域性资料和理论支持。

Abstract:
In this paper, the status quo of the sedimentary source-sink processes, dominant controlling factors, and their carbon cycle significance in the Kuroshio source region during the Quaternary were systematically reviewed. The results derived from comprehensive indicators of different disciplines consistently show that the main sources of the terrestrial detritus include nearby Luzon and continental shelf, as well as remote eastern Asian deserts. Their contributions to the studied area are dominantly correlated with sea level height and intensity of the East Asian monsoon on orbital, millennial, and centennial timescales, and ultimately controlled by the dual drives of both high- and low-latitude processes. In addition, the significant impact of human activity on the Kuroshio source region has occurred since 2.1 ka. Furthermore, there are also good correlations between the abovementioned processes associated with terrestrial inputs into the studied area, paleoproductivity, organic carbon burial in the sea, and atmospheric carbon dioxide concentration, indicating the significance of sedimentary source-sink processes in the Kuroshio source region for modulating the global carbon cycle. The abovementioned research work can provide regional data and theoretical support at low-latitudes for better predicting the climatic and environmental change trend in the future.
Key words:  Kuroshio source region  carbon cycle  source-sink processes  controlling factor  Quaternary
