杉木是我国特有的优质速生用材树种,一般认为它在浙江境内垂直分布的适生范围是海拔300～800米,在1000米以上山地杉木生长情况尚少见报道。本文仅据金华北山海拔1000～1160米的25块样地50株20～22年生杉木解析木资料,对杉木的树高、胸径和材积生长量进行初步探讨。由于调查面积不广,有一定局限性,仅为营造杉木林提供参考。 Cunninghamia lanceolata is a species of high-quality fast-growing timber that is unique to China. It is generally believed that the suitable range of vertical distribution in the territory of Zhejiang is 300 to 800 meters above sea level. The growth of fir in mountainous areas above 1,000 meters is rarely reported. Based on the data of 50 trees from 20 to 22 years old in 25 plots of 1000 ~ 1160 meters above sea level in north of Jinhua, this paper discussed the tree height, DBH and volume growth of Chinese fir. As the survey area is not wide, there are some limitations, only to provide reference for the fir plantation.
