Abstract: The paper aims to discuss the quantitative depiction method for high temperature in Shanxi. Based on the daily maximum temperature data of 69 meteorological stations in Shanxi Province from 1970 to 2013, this paper studied the spatial distribution of high temperature days from May to September respectively, and then based on the high temperature grades and high temperature duration, the high temperature regionalization indices were constructed, the zoning map of high temperature was completed. The results showed that the annual average high temperature days were more than 15 days in most areas of Yuncheng and the south of Linfen, and less than 2 days in the north and east of Shanxi. The high value centre of high temperature was in Yuncheng and the south of Linfen, the frequencies of which were 0.7 d, 4.5 d, 6.8 d, 2.3 d and 0.2 d from May to September respectively. The zoning map of high temperature and the spatial distribution of high temperature were similar.
