%X With more and more effects of human activities on natural climate variability,the climate change becomes enormously complex in the past 1000 years,which is the key period for linking the proxy data and instrumental observation periods.It is crucial to further reveal the role and mechanism of climate change in this special period despite the fact it is quite difficult due to scarcity and uncertainty of proxy data.To compensate for the deficiency of the proxy data,climate model is used as an important tool in paleoclimate research areas with the advantage in revealing the internal mechanism and response to external forcing factors of climate change.The sea-atmospheric coupled climate model ECHO-G has been proved to be an efficient climate model for both paleoclimate and modern climate research,but its simulation performance in China region needs to be further examined.In this paper,the simulated annual mean temperature series averaged in China region in last 1000 years is compared with two reconstructed proxy series,which was processed by Yang et al.18](named Y series)and Wang et al.19](W series)respectively,to validate the performance of the global climate coupled model ECHO-G in simulating the climate of China.The results indicate that the model successfully reproduces the medieval warm period(MWP)from 11th to 14th century,little ice age(LIA)from 15th to 19th century and present warm period(PWP),and the transition times from one period to another are also well corresponding to the reconstruction of Y series.Moreover,the features of simulated temperature in various areas of Eastern China are consistent with that in W series.It means that the model captures the essence characteristics of the temperature change in China during last millennium.Further study on the simulation shows that the West China can be divided into two parts based on the simulated temperature: North West China and Tibetan Plateau.The climate change in the former is well consistent with the East China but the latter is different in various seasons.There exists significant difference in temperature change between Tibetan Plateau and other regions in winter while the similarity prevails in other seasons.Temperature of Tibetan Plateau in winter is characterized by obvious upward trend in the last millennium,implying that it was cold in WMP in Plateau in winter.
