Abstract: Taking the day numbers of daily average temperature ≥30°C and the day numbers of daily maximum temperature ≥35°C as the index of high temperature disaster, the occurrence regularity of high temperature disaster for June to September was analyzed from 1961 to 2010 in Chongqing. The results showed that there was a large inter-decadal variation in occurrence of high temperature disaster. The most severe year of high temperature disaster was the year of 2006, while the year of 1987 is the lightest one. The general trend was that it was the lowest one in the 1980s and gradually increased in the 1990s, and reached the highest value in the 2000s. The spatial distribution of the day numbers of daily average temperature ≥30°C was the same as that of the day numbers of daily maximum temperature ≥35°C. The highest values were distributed at the areas of Kaixian, Yunyang, Wushan in the Northeast part and Fengdu, Fuling in the middle part and Banan,Shapingba,Beibei in urban district and Qijiang in the southwest part. The lowest values were distributed at the areas of Xiushan,Youyang,Qianjiang in the southeast part and Chengkou,Fengjie in the northeast part and Dazu,Rongchang in the west part.
