Classification on Forest Fire Types of Typical Stands in Mountainous Areas of Southern Gulang County
In view of the implementation of ecological projects in the southern mountainous area of Gulang County in recent years,the area of young forests has continued to increase,and the spatial continuity of combustibles has increased.Seven species of forest fires in the southern mountainous area of Gulang County were investigated using a sample survey method.The interior of a typical forest stand was investigated on tree height,diameter of breast height,branch height,crown width,moisture content,canopy density,combustible matter load,herb height,and litter thickness.Cluster analysis was performed to classify types according to factor characteristics,and the burning characteristics of different forest stand combinations were analyzed based on actual conditions.Seven typical forest stands were divided into 3 categories,with Populus davidiana in the first category,and prevention and control measures based on low-intensity fire were adopted;Ulmus pumila,Betula platyphylla,and Prunus sibirica belong to second category,and control measures based on low-intensity fire are adopted;Prunus sibirica,Platycladus orientalis,and Picea asperata belong to another category,and control measures based on crown fire are mainly adopted.Combined with fire prevention drills,it can be improved while improving the quality of caregivers,we can also achieve scientific and efficient prevention and fighting for forest fires.
