Analysis of the temporal and spatial distribution characteristics of forest fire and the weekend and holiday effects in Hunan Province
It is of great significance for the scientific management of wildfire sources and the prevention of forest fires to carry out research on the temporal and spatial distribution characteristics of forest fires as well as the weekend and holiday effects in Hunan Province,which are crucial for understanding the distribution patterns of forest fires.The research results revealed that the overall number of forest fires in Hunan showed a downward trend from 2016 to 2020.Specifically,92.74%of forest fires occurred between September and April of the following year,with more than two-thirds occurring from February to April,during which the highest frequency of forest fires was found in February.Forest fires occurred most in Yongzhou City,followed by Chenzhou City and Yiyang City,and the occurrence of forest fires was relatively lower in Changde City,Loudi City and Changsha City.Regions with higher kernel density values were primarily distributed in seven cities,including Yiyang City,Yongzhou City,Chenzhou City,etc.The area with the highest kernel density value was located in milldle Yiyang City,while most parts of Changde City and Changsha City were in the lowest kernel density value area.Eleven cities and prefectures including Xiangxi Tujia and Miao Autonomous Prefecture and Loudi City exhibited weekend effects.There were notable holiday effects during and around significant occasions like the Qingming Festival,Spring Festival,Arbor Day and National Day.
