中文摘要：
采用全球海气耦合模式ECHO-G的1000个模式年的长积分气候模拟方法分析了中国中世纪暖期温度的存在性与时空变化特征.结果表明：中国的中世纪暖期出现在公元1000—1250年间,但它不是一个持续稳定的暖期,而是存在峰谷起伏变化,其中最暖的30年（中世纪暖期鼎盛期）出现在1131—1160年.中世纪暖期中国的年平均和冬、夏季平均温度距平变幅西部最大,东部最小.其鼎盛期中国的温度距平相对于千年温度都是正值,中国东部的增温幅度由南向北逐渐加大,变幅为0.4℃—0.8℃,而中国西部的增温呈Ω型分布,且随着海拔高度的增加,增温幅度逐渐加大,最大增温达2.0℃—2.2℃.
英文摘要：
The existence,temporal development and spatial distribution of the Medieval Warm Period（MWP） of China are discussed based on the results of a 1000-year climatic simulation experiment from a global atmospheric-ocean coupled climate model ECHO-G.The results are as follows：The MWP in China occurs during 1000—1250AD,but it is not a steady and continuous warm period,there are peak-valley undulating changes in it.The warmest 30 years in the MWP appeared during 1131—1160AD.The temperature anomaies of anmual mean,winter mean and summer mean in the western China were the biggest during that time,but that of the eastern China the smallest.The regional temperature anomalies of whole China are positive at the prime of the MWP.The temperature increment becomes gradually bigger in the eastern China from south to north,from 0.4℃ to 0.8℃ progressively,while that of the western China is in a Ω pattern and increases with the altitude.The largest temperature increment is up to 2.0℃—2.2℃.
