Fig. 6. Relationships between five significant influence factors and leaf area index (LAI) in a spruce-fir valley forest in Xiao Hinggan Ling, China. Densitymid, the density of middle tree group (5 cm < DBH ≤ 10 cm); BAmajor, basal area of major trees; PBBNtotal, the proportion of basal area of broadleaf species to needleleaf species for total trees in a plot.
