Based on 29 sites' daily maximum temperature monitoring data of 7 provinces in East China from 1951 to 2008, the days of high temperature ( daily maximum temperature ≥ 35 ℃) and the intense heat of summer ( daily maximum temperature ≥ 38 ℃) have been extracted and their time-series have been analyzed by using Excel and SPSS tool; Besides their spatial distribution map has been made by GIS. The research results show that the spatial distribution of the high temperature and the intense heat of summer showed that it is high in the north and south but low in the middle. The average annual temperature which is ≥ 35℃ days in Southern Fujian， Jiangxi and Zhejiang Province are more than 20 days being high-risk areas; In the northern Shandong and Jiangsu Province where average annual high temperature days are more than 15 days are medium risk zones Anhui Province and Shanghai where average annual high temperature s are less than 10 days belongs to low-risk zones. The results can provide references for regional high temperature disaster risk management and disaster reduction.
