Characteristics of Fuel Moisture Content in Different Forest Types and Its Relationship with Environmental Factors in Guangxi
摘要
Abstract
To clarify the differences in the surface dead fuel moisture content among different forest types in Guangxi and to identify the key environmental factors affecting these variations,four typical forest types in Guangxi(Pinus massoniana forest,Cunninghamia lanceolata forest,Eucalyptus forest and broadleaved forest)were selected as research subjects.During the peak fire prevention period,surface dead fuel samples were collected and their absolute moisture content was measured.Multiple comparison analysis was conducted to examine the differences in moisture content among various for-est types and dead fuels.Redundancy analysis(RDA)was used to explore the effects of topographic factors and stand structural factors on dead fuel moisture content.The results indicated that the absolute moisture content of surface dead fuels varied significantly among different forest types,generally in the order of broadleaved forest,Cunninghamia lanceo-lata fores,Pinus massoniana forest and Eucalyptus forest.Within each forest type,coarse dead fuels and humus showed significantly higher moisture content than fine dead fuels.Elevation was found to be the most influential topographic factor affecting surface dead fuel moisture content,fo llowed by slope aspect.Stand density and canopy density were the most im-portant stand factors influencing the dead fuel moisture content in Cunninghamia lanceolata,Pinus massoniana,and Eu-calyptus forests.In broadleaved forests,multiple stand factors influenced the moisture content,but their effects were more dispersed.During the peak fire prevention period,fire risk monitoring should focus on forest types with lower moisture con-tent,and differentiated fuel management measures should be developed based on topographic and stand characteristics.关键词
