深入研究我国因祭祀引发森林火灾的时空分布特征,掌握祭祀火灾的变化规律,对科学管控火源管理、预防森林火灾具有重要的意义.研究结果表明:我国祭祀火灾主要分布在清明节和春节期间,时间主要集中在2、4月,近10年我国因祭祀引发森林火灾次数呈降低趋势;祭祀火灾大部分发生在我国南方,其中,广西、湖南、湖北等地是我国因祭祀引发森林火灾的高发区域,尤其是植被覆盖率较高且祭祀活动丰富的广西.因此,建议广西等南方地区应在火源发生最频繁的春节、清明节期间进行重点监控,尤其是高温、大风等气象条件下的野外火源管控.
It is of great significance to scientifically manage and control fire source management and prevent forest fires to carry out research on the temporal and spatial distribution characteristics of forest fires caused by sacrifices in China,and to grasp the changing laws of sacrifice fires.The research results showed that the sacrificial fires in China are mainly distributed during the Tomb Sweeping Festival and the Spring Festival,and the time is mainly concentrated in February and April.In the past 10 years,the number of forest fires caused by sacrificial activities in China has been decreasing.Most of the sacrificial fires occurred in southern China.Guangxi,Hunan,and Hubei provinces are high-incidence areas of forest fires caused by sacrifices in our country,especially Guangxi,which has high vegetation coverage and abundant sacrifices.Therefore,it was recommended that southern regions such as Guangxi should focus on monitoring during the Spring Festival and Tomb Sweeping Festival,when fire sources occurred most frequently,especially the control of wild fire sources under meteorological conditions such as high temperature and strong wind.
