Abstract

In order to effectively reveal spatial heterogeneity and relevance of forest fire risk, and provide a scientific reference for allocation and regional linkage of fire prevention and control resources, take the natural factors and the human factors into consideration comprehensively, entropy method and comprehensive index method were used to assess forest fire risk in Yunnan province. Then, spatial pattern of the risk was studied by utilizing spatial auto correlation model. The results show that the risk of forest fire in western Yunnan is higher than that in the east, and most areas feature higher risk and high risk level, especially in northwest, west and central part. There are two fire risk trend lines, one extending from the northwest along the middle part to the northeast, which demonstrates a trend of high at both ends and low in the middle. The other one is low in the north and south, and high in the middle. The fire risk shows spatial agglomeration in space, but its degree of significance is average with weak local correlation. © 2021 China Safety Science Journal
