中文摘要	选取PMIP2计划中ECBilt--CLl0--VECODE模式的结果, 对比中全新世f6 kaBP)气候对于现代气候的变化, 探讨了植被在中全新世气候变化中的意义.中东亚干旱区受西风坏流影响, 而东亚地区6 kaBP季风深入, 不同大气环流的影响导致两区域大尺度气候特征差异大, 同时该\|j寸{期植被的变化增强了气候系统对轨道参数变化的响应: 一系列气候要素对植被的动态响应导致气温、降水都因植被反馈而发生较大变化, 但是该模式的结果存在低估6 kaBP升温幅度的缺陷, 尤其是对冬季温度的模拟; 即使耦合植被后有所改善, 但对6 kaBP气候变化的驱动因子及其相互关系的研究仍需深入, 同时对局地气候变化的物理机制还需改进
英文摘要	The significance of vegetation in 6 kaBP climate variability was analyzed by comparing the midholocene climate with the pre-industry climate, with the help of the results of ECV model. The mid-latitude arid central Asia was climatically dominated by westerly circulation while the monsoon circulation deeply was embedded in the inland. Influenced by different atmospheric circulations, the two regions exhibited large differences in large-scale climatic features. At the same time, the flourished vegetation enhances the response of the climate system to the earth’s orbital parameters. As a result, we found temperature and precipitation changed much, which resulted from the dynamic response of a series of climatic factors because of the vegetation feedback. However, the model has a disadvantage in that it always underestimates the range of warming in 6 kaBP, especially for a simulation of winter temperature. Even if coupling vegetation is improved, driving factors of climate change in 6 kaBP and their relationships still need to be researched into. Moreover, the physical mechanisms of some areas require improvement
