Study on Forest Fire Risk Assessment and Zoning in Nanning City
Based on the technical system of forest fire risk,the forest fire hazard,forest fire risk,forest fire coping capacity and control zoning were studied by using the survey data of forest fire risk factors in Nanning.The results showed that the forest fire hazard index ranged from 0.002 2 to 0.239 7,the forest fire risk index ranged from 1.040 0 to 3.000 0.Villages with high fire risk were mainly concentrated in areas with rich forest resources,complex topography and frequent human activities(e.g.,around Daming Mountain and city-county junctions).The forest fire coping capacity index ranged from 0.122 0 to 0.611 0,with high values observed in national forest farm areas and economically developed urban areas.Based on the forest fire risk assessment and forest fire coping capacity of Nanning City,and considering the actual fire prevention work and ecological location of Nanning City,7 zones of forest fire prevention and control are delineated.The evaluation and zoning results are in line with the objective reality of Nanning City,which can provide references and suggestions for the next decision-making and deployment of forest fire prevention in Nanning City.In the future,dynamic risk assessment can be carried out by updating forest fire risk factor data in time,combined with meteorological and other real-time data,so as to provide more detailed management suggestions for forest fire prevention and control in different periods.
