摘　　要：利用中国气象局提供的1951-2004年中国均一化历史气温数据,分析了近50年我国地面气温及各区域气温的年际变化和长期变化趋势。结果表明,近50年来,我国气温呈持续增长的趋势,尤其是从20世纪80年代初期开始,气温的增长非常明显,其中冬季温度上升趋势最为明显,春、秋季增暖趋势次之,夏季增暖趋势最小;1951-1965年,西南区呈明显的降温趋势,1965年以来,气温呈比较弱的上升趋势;其他6个区域的气温都呈一定的上升趋势。同时,各个区域的增温大小有着明显的不同,东北区、西北区、青新区的增暖趋势比较强,东南区、中南区的增暖趋势比较弱。Based on the homogenization temperature data from 1951 to 2004,the annual variation and long-term trend of the temperature of China were analyzed.Then regional temperature change was interviewed.Results showed that the temperature of China increased continuously in recent 50 years,especially from the early 1980s.And the seasonal temperature change of China was also very clear.The temperature increase was the fastest in winter and slowest in summer.It can be founded that the temperature of southwest region of China decreased from 1951 to 1965 and increased after that period.The temperature of other six regions of China increased from 1951 to 2004.Meanwhile,the increase trend of temperature of northeast region,northwest region,Qinghai-Xinjiang region of China was relatively stronger than that of southeast region and central-south region.
