中文摘要	选用甘青地区达连海、青海湖、苏家湾、大地湾4个典型高分辨率的钻孔资料进行对比分析,阐明了该地区末次冰消期以来气候变化规律与主要气候事件,初步探讨了该地区植被纬向时空演化规律.结果显示末次冰消期大致开始于15.2～14.6 ka BP之间.冰消期期间该地区气候表现为冷暖波动频繁.气候不稳定.植被类型由东向西为草原-荒漠化草原.全新世早期阶段10.4～8.2 ka BP气候表现为温干,植被类型由东向西为疏林草原-草原.全新世中期8.2～4.3 ka BP气候温暖湿润,植被发育良好,由东向西出现森林-森林草原植被.4.3 ka BP以后该地区气候总体向凉干方向发展,3.9～3.4 ka BP期间陇中地区气候波动较显著,植被类型草原-森林草原交替出现.晚全新世后期2.3～0 ka BP气候冷干,从东到西发育草原-荒漠化草原植被.
英文摘要	The paper analyses the high resolution pollen records of Dalianhai lake, Qinghai lake, Su-jiawan and Dadiwan sediment in Gansu-Qinghai area since the last deglaciation. And disscuses the climate change,cold-dry climate incidents and vegetation distribution from east to west in this area. It is shown that the late glacial began between 15. 2～14. 6 ka BP, the climate was cold and humid during the early period, cold and dry during the late period,and totally unstable;meadows-desert steppe vegetation developed from east to west. In early Holocene the climate was temperate and dry, shrub meadows-meadow appeared in this area. During the middle Holocene climate was warm and wet, conifer and broad-leaved deciduous mixed forest developed. Climate became cold and dry since 3. 9～3.4 ka BP. In early period climate was relatively warm and wet, meadows-shrub meadow vegetation developed in east of the area; in late period(2.3～0 ka BP) climate was dry and cold, vegetation involved to meadows-desert steppe.
