Abstract: The paper aims to study the distribution of high temperature disaster in different counties of Heze. According to temperature data from meteorological stations of 8 counties and 1 district in Heze during 1970- 2014, the authors selected days whose temperature was greater than 35℃ and the annual extreme highest temperature to analyze the basic characteristics of high temperature weather. Risk index method, expert scoring method, analytic hierarchy process and comprehensive weighted score method were used. Based on full consideration of the risk of hazards, disaster environmental sensitivity, vulnerability and disaster prevention and mitigation, the disaster risk distribution maps of Heze were obtained combined with GIS system. The results showed that: Dongming County, Cao County and Chengwu County were high risk area of high temperature; Juye County and Shan County were low risk area, and other counties were medium risk area. This research can provide theoretical support for prevention and mitigation of high temperature disaster in Heze.
