摘  要:
以浙江省建德市新安江林场的北美红杉人工林为研究对象,在标准地调查的基础上,选取并测定解析木数据,对其胸径、树高及材积进行分析。结果表明:随着年龄的增大,北美红杉树高和胸径生长表现为"直线形",而材积生长则表现为"S"型;33年生北美红杉树高、胸径、材积总生长量分别为23.00 m,30.6 cm,0.3430 m3,年平均生长量分别为0.70 m,0.93 cm,0.0104 m3;连年生长量和平均生长量曲线并没有交叉,该树种还处于速生阶段。北美红杉比当地杉木生长快,可在相近区域推广造林。

摘  要:
Taking growth forest of Sequoia sempervirens plantation of Xin'an River Forest Farm in Jiande City of Zhejiang Province as research object, on base of plot investigation, stem analysis of tree height, diameter of breast height(DBH) and volume of timber were drawn to determine. The results showed that the growing straight arrows sequence curves in tree height, DBH, and the growing "S" curves in tree volume of timber with the age of plantation increased. The total increment of tree height, DBH and volume of timber was 23.00 m, 30.6 cm, 0.3430 m3, respectively. The average annual growth of 33-year-old S. simpervirens was 0.70 m, 0.93 cm and 0.0104 m3, respectively. There was no interaction between the annual growth and the mean growth, this result indicates that the tree were still in the fast growth stage. Moreover, the S.sempervirens grow faster than Chinese fir, and it can be used as one of the local afforestation species.
