中国落叶松林胸径–树高相关关系的探讨
Allometric Relationship between Tree Height and Diameter of Larch Forests in China
摘要
Abstract
184 plots from larch (Larix Mill.) forests across China were sampled to characterize the height-diameter relationships and investigate the effects of structure and climate on them based on the power functionH =aDb. The results showed that the height-diameter relationship differed greatly among species:b-value ofLarix gmelinii(0.65±0.11) andL. olgensis(0.68±0.10) were significantly higher thanL. mastersiana(0.51±0.17) andL. potaninii(0.54±0.15) (F=2.34,P=0.026). These differences were significantly influenced by mean annual temperature, but no statistic relationships were detected between stem density, total basal area and mean annual prepetition againstb-value. These results indicated that as mean annual temperature increased, a higher proportion of biomass was allocated into diameter growth than height growth (R2=0.09,P<0.001).关键词
