摘　　要：热带西太平洋对现代全球气候系统有举足轻重的影响,其中"西太平洋暖池"区的变异对调节全球气候发挥着极为重要的作用。越来越多的证据表明在轨道—亚轨道尺度上暖池对全球古气候的变化也有着重要的调控作用,低纬热带西太平洋已成为近十几年来古海洋学研究的重点地区之一。从表层海水古温度和古生产力记录、千年尺度的快速气候变化、厄尔尼诺—南方涛动(El Nio-Southern Oscillation,ENSO)式变化以及暖池强弱变动及其位移等角度梳理了西太平洋暖池区古海洋学研究的现状,综述了目前对暖池区海洋环境演化及其气候效应的已有认识,针对目前暖池区古环境研究的状况探讨了未来工作中应重视的科学问题。The tropical western Pacific has significant influence on the modem global climate system, and variations of the Western Pacific Warm Pool play an extremely important function in adjusting the global climate. There is growing evidence on the great role of the equatorial Western Pacific in regulating global paleoclimate changes on orbital to suborbital timescales. The low latitude tropical western Pacific has become a focus in the study of paleoceanography last decade. Progress in the paleoceanogrpahy of Western Pacific Warm Pool is reviewed by evaluating the current research situation mainly related to sea surface temperature and plaeoproductivity, abrupt climatic events on millennium timescales, ENSO-like events,intensity and shift of the Western Pacific Warm Pool. An overview about the present knowledge of environmental evolution in the Western Pacific Warm Pool and its climatic impacts is provided with the discussion of some valuable scientific issues in future studies.
