As one of the climate change risk which profoundly affected the natural environment and human society, heat waves has aroused increasing attentions all around the world. Based on VSD(The Vulnerability Scoping Diagram), the evaluation index system of t heat waves risk is constructed. With the method of exploratory spatial data analysis, the spatial-temporal characteristic, hot spots evolution and spatial differentiation of heat waves risk in Fujian Province from 2000 to 2015 are carefully examined. The results show that: ① The index of heat waves risk is decreasing in Fujian Province, at the same time, the internal transitions among different risk levels are obvious . ② The spatial distribution of heat waves risk in Fujian Province has the "layer structure", and the risk index varies from central to peripheral areas as characteristic of "low-high-low". ③ The spatial agglomeration degree of heat waves risk decreases. The hot spots presents a tendency of shrinking, from "multi-core" to "dual core", while the cold spots presents a tendency of stabilizing in the northeast. ④ The heat waves risk in Fujian Province can be divided into 5 types, including high risk area of capital-deputy provincial area, sub-high risk area of prefecture-level city district, medium risk area of river valley, sub-low risk area of coastal plain, and low risk area of eastern-inland mountainous area. This result is the prejudgment of spatial evolvement of heat waves risk of Fujian Province in the future. It also can provide references for risk management and public service facilities .
