摘 要: 研究选取2012年至2018年四川省森林火灾信息,结合四川省行政区划图与地形图,研究了四川省森林火灾的时空分布。使用地理信息系统(geographic information system,GIS)空间分析技术分析了森林火灾在四川省境内的影响力。结合地形因子、人为因子、气象因子,利用层次分析(analytic hierarchy process,AHP)法对四川省森林火灾等级进行评价。这在一定程度上可以为四川省森林火灾的预防提供技术支持和科学依据。
关 键 词: 地理学;地理信息科学;森林火灾;时空分布;层次分析法;GIS空间分析

Abstract: This paper studied temporal and spatial distribution of forest fires in Sichuan province, which was conducted by the forest fire information of Sichuan province from 2012 to 2018, combined with Sichuan’s administrative map and topographic map. It also analyzed the influence of forest fire in Sichuan by using GIS spatial analysis methods. Combined with topographical factors, man-made factors and meteorological factors, analytic hierarchy process (AHP) method was used to evaluate the forest fire risk level. To a certain extent, it can provide technical support and scientific basis for the prevention of forest fire in Sichuan province.
Key words: geography; geographic information science; forest fire; temporal and spatial distribution; analytic hierarchical process method; GIS spatial analysis
