The Paleoclimate Modeling Intercomparison Project (PMIP)is a long standing initiative endorsed by both WCRP/CLIVAR/WGCM and PAGES. It has provided an efficient mechanism for coordinating paleoclimate modeling and data activities to facilitated valuable discoveries on the mechanisms of climate change, the identification of key feedbacks operating in the climate system and, through model evaluation, the capability of climate models to reproduce climates different from today. Two phases of PMIP have passed since PMIP was launched in 1991, I. E. Phase 1 (1991 ～ 2001) and phase 2 (2002 ～ 2007). The third phase (phase 3) of PMIP has been kicked off since 2008. This paper reviews the advances of PMIP in the last 10 years and summarizes its key themes of future research plan which include 1) Evaluation of earth system models at 6kaB. P. And 21kaB. P. (Theme 1), 2)Experiments on interglacials and warm periods (Theme 2), 3)Research on abrupt climate changes (Theme 3)as well as 4)Uncertainties: characterization and understanding(Theme 4).%国际古气候模拟比较计划(PMIP)是古气候领域里的一项长期开展的大型国际研究计划.该计划的主旨是利用气候数值模式,通过开展一系列针对古气候变化的模拟试验理解全球气候变化的机理,确定气候系统内部的各种影响气候变化的关键反馈因子;通过比较不同气候模式对不同于现代气候(古气候)的模拟能力评价模式的优劣,进而促进气候模式的发展;同时也为全球变化背景下利用气候模式预估未来气候变化提供借鉴.PMIP白1991年酝酿开始至今经历了PMIP1(1991～2001年)、PMlP2(2002～2007年)两个阶段,并正在开展第三阶段(PMfP3)(2008～)的研究.本文简要回顾了近10年来PMIP研究进展及概述了未来PMIP将要开展研究的重点领域和方向,主要包括4个主题:1)基准(benchmak)时段(6kaB.P.和21kaB.P.)模拟;2)间冰期和温暖期气候模拟;3)快速气候变化模拟;4)不确定性研究.
