太白山北坡太白红杉(Larix chinensis)胸径生长规律研究
Regularities of DBH Growth of Larix chinensis in the North Slope of Taibai Mountain
摘要
Abstract
Five commonly used growth models were applied in fitting the average DBH growth process of Larix chinensis growing in the origin center, suitable region, and alpine timberline, respectively. The optimal models were selected and the variation regularities of the growth were analyzed. The results demonstrated that the quadratic model was the most suitable one for the growth of L. chinensis growing in the origin center and suitable regions, while those growing in alpine timberline had to be fitted piecewise by power function and Logistic equation. Current annual increment and mean annual increment growing in the origin center and suitable regions were higher than that in alpine timberline, reached to 0. 30 cm and 0. 20 cm, respectively. The maximum average annual growth was observed in the trees with the age of about 70 a growing in alpine timberline, while it was about 40 a in the origin center and suitable regions, earlier than those in alpine timberline.关键词
