摘要
为采取适当的防控措施以减少森林火灾危害,本文采用空间自相关分析、概率密度估计、数据热点分析等方法通过探究了内蒙古2019-2024年森林火灾时空分布特征。研究表明:(1)从时间分布上看,研究区域森林火灾总体呈现逐年波动下降的趋势;内蒙古森林火灾分布具有明显的季节性,主要集中分布在春夏两季;每年4-8月为内蒙古森林火灾重点防控期。(2)从空间分布上看,可划分为两个主要中心。东北部大兴安岭沿线森林火灾发生频率由极高逐渐降低;内蒙古中部呼和浩特、包头、鄂尔多斯三市交界区域森林火灾发生频率由中度逐渐降低,呈现显著空间正相关关系。
In order to take appropriate prevention and control measures to reduce the harm of forest fires,this article uses methods such as spatial autocorrelation analysis,probability density estimation,and data hotspot analysis to explore the spatiotemporal distribution characteristics of forest fires in Inner Mongolia Autonomous Region from 2019 to 2024.Research has shown that:(1)In terms of time distribution,forest fires in the study area generally show a fluctuating downward trend year by year;The distribution of forest fires in Inner Mongolia Autonomous Region has obvious seasonality,mainly concentrated in spring and summer;The period from April to August each year is the key prevention and control period for forest fires in Inner Mongolia.(2)From a spatial distribution perspective,it can be divided into two main centers.The frequency of forest fires along the Greater Khingan Range in Northeast China has gradually decreased from extremely high;The frequency of forest fires in the border areas of Hohhot,Baotou,and Ordos in central Inner Mongolia gradually decreases,showing a significant spatial positive correlation.
