- Abstract
[Objective] To understand the relationship between leaf biomass and radial growth of Larix olgensis in Xiaoxing'anling Mountains. [Method] The relationship between leaf biomass and radial growth at individual tree level and at different direction interval of individual tree was studied based on pipe model theory, and the correlation between crown distribution and radial growth was analyzed. [Result] Leaf biomass was significantly and positively correlated with stem diameter, basal area and sapwood area at breast height and height to crown base, as well as basal area growth in recent 1, 2, 3 and 5 years, and the leaf biomass model using breast height basal area as a predictor had the best fitting effect. The leaf biomass in different direction interval of a single tree was significantly positively correlated with the stem radius and basal area at the corresponding DBH and the height to crown base, and the growth of basal area in recent 1, 2, 3 and 5 years. [Conclusion] When estimating the leaf biomass per tree, the basal area of breast height is the best predictor. The leaf biomass of different direction interval in a individual tree is significantly and positively correlated with the stem radius, basal area and basal area growth of corresponding directions, and there is a certain correlation between crown displacement and pith eccentricity.
