Abstract
[Objective]Identifying the combustible load patterns per unit area of different dominant tree species(groups),age groups,and canopy closure levels in tree forests can provide a scientific reference for obtaining forest combustible types and distribution data.[Method]Based on a survey on 235 standard plots of tree forests in Ji'an City,laboratory measurements were conducted on the survey samples.[Result]Through data comparison and analysis,it was found that the combustible load per unit area of different dominant tree species(groups)in the tree forest was mixed tree species(groups),broad-leaved tree species(groups),and coniferous tree species(groups)in descending order;The fuel load per unit area of different age groups was basically mature forest>near mature forest>middle aged forest>young forest;The combustible load per unit area of different canopy closure levels was in descending order of high canopy closure,medium canopy closure,and low canopy closure.The research results are of great significance in guiding the analysis of the types and distribution of forest fuels in different types of tree forests in forest fuel surveys.关键词
