Abstract

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,Schefflera 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.

Key words： wildland-urban interface; forest fire risk class; combustible material control; terrestrial laser scanning; analytic hierarchy process
