摘　　要：利用1951~2012年丽江站逐月平均气温，对丽江近62a气温变化特征进行了的研究。得出以下主要结论结论：近62a丽江的气温呈明显上升趋势，年平均气温上升幅度为0．16℃·（10a）-1，其中冬季上升速度最大，其次是春季、夏季，秋季上升速度最小。在1994年前后存在年平均气温突变，各季节突变时间点不同，春、夏、秋、冬各季节突变年分别在2003年、1981年、1992年、1995年。丽江冬季异常冷暖年较少，一共只出现4次，秋季的异常冷暖年最多出现15次，异常增暖现象主要出现在20世纪90年代以后。Based on the meteorological data during 1951~2012, the change trends and characteristics of temperature in Lijiang for last 62 years had been analyzed and studied. The results showed that the temperature had increased remarkably in Lijiang area during recent 62 years. The rising annual average temperature was 0.16℃· （10a） -1. The most obvious warming occurred in winter, followed by spring and summer, the warming rend in autumn was weak. The average annual temperature mutated around the year of 1994. Each season mutation time occurred in different years, and spring, summer, autumn, winter mutation time respectively occurred in 2003, 1981, 1992, and 1995. Abnormal changes in temperature in winter were less with only four times in total. Abnormal changes in temperature in autumn were 15 times. The abnormal heating phenomenon mainly appears after the 1990s.
