摘要
为考虑致灾因子时空异质性特征、体现孕灾环境和承灾体作用下的自然固有火险等级属性,达到动态评估森林火灾风险的目的,利用地理信息系统(GIS)手段获取和处理气象因子、地形因子、植被因子和人为因子4类共9个指标,采用层次分析法确定指标权重,结合现行森林火险区划标准叠加分析并区划三亚市森林火灾风险。通过与历史火灾数据比对,验证评估方法的合理性。结果表明,三亚市总体森林火险等级较低,绝大部分处于中风险和较高风险范围,高风险区主要存在东、西线高速公路以北第一层山脊线以内、往南至滨海区域内。
In order to consider the temporal and spatial heterogeneity of hazards,reflect the natural inherent fire risk grade attribute under the action of the disaster-pregnant environment and the hazard-bearing body,and achieve the purpose of dynamically assessing forest fire risks,the geographic information system(GIS)method was used to obtain and process 9 indicators in 4 categories:meteorological factors,topographic factors,vegetation factors,and man-made factors.The analytic hierarchy process was used to determine the index weights.Combining with the current forest fire risk zoning standards,forest fire risk in Sanya City was overlay analyzed and divided.Through comparison with historical fire data,the rationality of the evaluation method was verified.The results showed that the overall forest fire risk level in Sanya is relatively low,and most of them are in the medium and high risk range.High-risk areas mainly range from the first ridge-line which is the north of east and west highways to the south by the coastal area.
