龙胜县森林火险等级区

以广西龙胜县为研究区，调查分析该县森林火险状况及影响要素，结合森林资源载量及森林防火实际，选取树种（组）燃烧类型、人口密度、气象因子、火灾次数等11项主要林火影响因子，综合运用层次分析法(AHP)、聚类分析法及ArcGIS空间分析法，区划森林火险等级。结果表明，各村（分场）可区划为Ⅰ（高火险区）、Ⅱ（中火险区）、Ⅲ（低火险区）3个火险等级；Ⅰ、Ⅱ、Ⅲ级火险区面积分别占研究区总面积的35.47%、38.33%、26.20%。高火险区主要分布在东部和南部，中火险区集中于西部和北部，低火险区分散在高、中火险区之间。区划结果有利于总结、突出研究区森林火情特点和重点。

Forest Fire Risk Classification in Longsheng County

The forest fire risk situation and influencing factors in Longsheng County of Guangxi were investigated and analyzed. Based on the forest resource carrying capacity and actual forest fire prevention, 11 main forest fire influencing factors were selected, including tree species (groups) combustion type, population density, meteorological factors, and fire frequency. The analytic hierarchy process (AHP), cluster analysis, and ArcGIS spatial analysis were comprehensively used to classify the forest fire risk level.The results showed that all forest zones from different villages (forest farm branches) could be divided into three fire risk levels: I (high fire risk area), II (medium fire risk area), and III (low fire risk area); the areas of Level I, II, and III fire danger zones accounted for 35.47%, 38.33%, and 26.20% of the total research area, respectively. High risk areas were mainly distributed in the east and south, medium risk areas were concentrated in the west and north, and low risk areas were scattered between high and medium risk areas. The zoning results were conducive to summarizing and highlighting the characteristics and key points of forest fire in the research area.
