【英文摘要】The project purposes reconstructing the Holocene environment variation history in the Okinawa Trough and it's adjacent continental shelf. Based on a multivariable approach utilizing foraminifer and pollen, geochemistry, sedimentology and mineralogy, it studied the evolution of marine environmental conditions during the Holocene in the study area. The study found out the response characteristics of the study region to the periodical fluctuations of environment on millennial-scale, the abrupt climate events, and the El Ni?o variability occurring during the Holocene. The study shown that during the Holocene, three periods of the regional climate changes can be identified. During the early Holocene it shifted gradually from cold to warm; the middle Holocene Climatic Optimum was warm; and the optimum climate was replaced by a cool and fluctuant one during the late Holocene. And, global high-frequency cycles, including the millennial scale cycle and the atmosphere-ocean inter-oscillation induced multi-decadal cycles such as the PDO and NAO, are assuredly exist in the study region.Comparison of our results with the ice core and terrestrial paleoclimatic records in the Chinese continent and other regions of the world suggested they are almost comparable and strongly coupled. This study reconstructed the evolution process of w arm current system of the East China Sea and the Yellow Sea during the Holocene. modern Tsushima W arm Curent began to develop along with the rising of sea 1evel and finally form ed at about 8.5 ka BP, The Yellow Sea W arm Curent has appeared at about 6.4 ka BP.The study is important to enrich the marine records of the Holocene environmental changes in the Low-latitude areas, and will improve our understanding of the connection between the different records of the global. Also, it will be significant on discussion of the mechanisms for global climate and environment variability during the Holocene
