The spatial and temporal variations of ≥10°C annual accumulated temperature (AAT10) were analyzed by using the linear trend line method, cumulative anomaly method and the multiple linear regression model (MLRM) interpolation method based on the daily meteorological observation data from 104 meteorological stations in Southern China and surrounding 39 meteorological stations from 1960 to 2011. The results show that: (1) From time scale point of view, the climatic trend of the AAT10 increased with an average of 7.54°C/decade in Southern China since 1960. The area of AAT10<6000°C decreased from 1960 to 2011, and the area of 6000°C
