摘要
摘要:冲绳海槽处于东海与西太平洋边缘的交界处，不仅对全球气候变化响应敏感，其环境变化也影响着东亚边缘海，乃至东亚大陆的环境，是研究古海洋环境的理想区域。该区域的古海洋环境研究多集中于末次冰盛期以来，因此本文以冲绳海槽为主体，总结了该区域末次冰盛期以来古海洋环境变化的相关研究，主要包括3个方面：古海平面、温度和盐度等；沉积物来源及其演化；黑潮及其对海洋环境的影响。该区域末次冰盛期以来的环境变化可大致分为，主要由海平面控制为主的末次冰盛期-早全新世和由黑潮、季风等因素控制的早全新世-现代两个主要的阶段。沉积物主要来自古黄河、长江、日本、台湾岛以及火山喷发物质等，但不同区域、不同时间的物质来源存在差异。另外，黑潮是该区域最主要的海流，其路径和强度末次冰盛期以来经历多次变化，并对其他海洋环境要素产生重大的影响。综合上述研究，提出未来应该系统建立冲绳海槽海洋环境演化历史、加强黑潮对周边流系的影响和陆源物质源-汇过程的系统研究。

Abstract:The Okinawa Trough, located at the boundary of the East China Sea and the West Pacific Ocean, is not only sensitive to changes in global climate as well as the local environment, but also affects the environment of the East Asian Marginal Sea and the Asian continent. It is an ideal area to investigate paleoceanography and continent-ocean interactions because of its continuous sedimentation and the rapid paleoenvironmental changes. Most studies of the paleoceanography in the region have focused on the period since the Last Glacial Maximum. This study attempts to summarize those studies, examining three main aspects:(1) The sea level, paleotemperature and paleosalinity changes, (2) the change and trace of the sediment provenance, and (3) the Kuroshio Current and its impact on the oceanic environment. Firstly, the environmental changes since the Last Glacial Maximum in this region can be roughly divided into two main stages:(1) The Last Glacial Maximum to the Early Holocene, in which environment changes are largely determined by sea level, and (2) the Early Holocene to present, in which environmental changes are heavily influenced by factors such as the Kuroshio Current and monsoons. Secondly, the sediments in this area are mainly from the Yellow River, Yangtze River, Japan, Taiwan Island and volcanic eruption, varying in proportion over time. Thirdly, the Kuroshio Current, as the most important current in the region, has undergone many changes since the Last Glacial Maximum, and has exerted significant influences on other elements of the marine environment. As a matter of conclusion, it is urged that scientists in the future do more systematic research of the evolution of the oceanic environment of the Okinawa Trough, the source-sink process of terrestrial materials, and the impact of the Kuroshio Current on the surrounding current system and overall oceanic environment.
