Abstract：Surface Air Temperature (SAT) data over China were used. Quality control process were applied to them, and the homogeneity of the series and the spatial sample errors were taken into consideration. The amplitude of China climate warming in recent 55 years was calculated. The results show: 1998 is the warmest year during the period, the SAT anomaly reached 1.10 ℃ (based on the climatology during 1971-2000, the same with the following text). In addition, the following 8 years saw 7 warmest years during 1951-2005, which are 2002(0.88℃),1999 (0.86℃),2004 (0.86℃),2005 (0.72℃),2003 (0.68℃),2001 (0.63℃), which deserves more attention.
