摘要
文章利用研究区的SPOT-6遥感数据和1:50000的基础地理矢量数据,在GIS技术支持下,以植被类型、海拔、坡度、坡向为林火影响因子,综合运用ArcGIS的空间分析,在较小空间尺度上进行了森林火险等级区划研究。
Based on the SPOT-6 remote sensing data and 1∶50000 basic geographic vector data in the study area,with the support of GIS technology,the vegetation type,altitude,slope and aspect were taken as the influencing factors of forest fire,and the spatial analysis of ArcGIS was comprehensively used to study the forest fire danger level division on a small spatial scale.
