The classification of forest fire risk assessment is an important basis for the integrated forest fire risk assessment.According to the forest fire risk regionalization method,in this paper,seven factors were selected,including combustible flammability,combustible loading,wild fire source,historical fire,population distribution,topography and geomorphology,and historical meteorological conditions.The weight of each factor was analyzed by using the analytic hierarchy process.Combined with the actual situation of the study area,its risk assessment is divided into four grades:high-grade danger zone,middle-high grade danger zone,middle-low grade danger zone and low-grade danger zone,which provides some theoretical basis for urban forest resources management and forest fire prevention.
