摘要：森林火灾风险评估是火灾预防的基础。以广州市森林和城镇交界域的16种主要林分类型为研究对象,利用地基激光雷达数据进行精准、非破坏性的分析,获取林分特征与结构指标,选取11种影响林分火灾危险性的静态因子,运用层次分析法,综合评价不同林分类型的火灾危险性。结果表明:火灾危险性较高的林分类型为桉树林、杉木纯林、米锥林,其中桉树林火险等级为四级,火灾危险性最高;杉木纯林、米锥林的火险等级为三级;杉阔混交林、黧蒴林、枫香林、樟树林、鸭脚木林、锥栗林、华润楠林、大叶相思林、尖叶杜英林、台湾相思林、润楠林、阔叶混交林的火灾危险性依次降低,且火险等级为二级,火灾危险性一般,其中杉阔混交林在二级火险林中火灾危险性最高;木荷林的火险等级为一级,火灾危险性较低。通过分析中高火险林分类型的林分特征与结构,提前对林地进行有计划的可燃物管控和改造以降低森林火灾风险,可使森林防火工作更有针对性,进而提高交界域的森林防火效率。
Forest fire risk assessment is the basis for fire prevention.Sixteen major forest stand types in Wildland-Urban Interface of Guangzhou City were studied,using terrestrial laser scanning data for precise,non-destructive analysis results to obtain forest stand characteristics and structural indicators.The fire risk of different forest stand types was comprehensively evaluated with 11 factors relating to the fire risk of forest stands via the analytic hierarchy process.The results showed that Eucalyptus forest(EF),Cunninghamia lanceolata forest(CLF)and Castanopsis chinensis forest(CCF)were classified as higher fire risk,specifically,EF with fire risk Class IV,CLF and CCF with fire risk Class III.The fire risk of mixed fir and broad forest,Acacia auriculiformis forest,Liquidambar formosana forest,Cinnamomum camphora forest,Scheflera heptaphylla forest,Castanea henryi forest,Machilus chinensis forest,Acacia auriculiformis forest,Elaeocarpus rugosus forest,Acacia confuse forest,Machilus nanmu forest and broadleaf mixed forest decreased in order.Among them,the mixed fir and broad forest had the highest fire risk in the secondary fire risk forest.The fire risk level of Schima superba forest was classified as Class I,with a low fire risk.By analyzing the stand characteristics and structure of medium and high fire risk forest types,targeted combustible material control and modifications were removed to reduce stand combustibility and to improve the efficiency of forest fire prevention.
