A Study of Growing Characteristics of Cinnamomum camphora Plantations in Sichuan
摘要
Abstract
Studies were made of the growth pattern of height,DBH and volume of Cinnamomum camphora trees in Sichuan Province.The results showed that the growth of Cinnamomum camphora trees had a strong adaptability.The average height of 27-year-old trees could reach 15.80 m.They could have an average DBH of 35.1 cm and a volume 0.6790 m3.At the initial plantatian stage the growth of Cinnamomum camphora trees were slow,but their annual DBH growth and height growth would achieve the peak at about 10th or 12 th year.After 12 years their annual DBH growth and height growth still maintained a higher growth tendency.Their annual volume growth and average volume growth continued increasing with the increase of the tree age,and still maintained a quicker growth velocity at 27th year.The growth dynamic models of height,DBH and volume of Cinnamomum camphora were established with the Logistic Equation.Three regression equations were y=35.4356/（1＋11.59×e-0.1942x）,y=16.429/（1＋12.6749×e-0.1906x）,y=0.9639/（1＋107.5×e-0.2043x）.关键词
