摘  要:
本文利用89株杉木样木资料建立了绩溪县杉木的生长方程并进行了分析。结果表明,树高、胸径、材积的生长方程均可采用逻辑斯蒂方程进行模拟;绩溪县杉木的主伐年龄可确定为40年;现行的杉木一元材积表不适宜于绩溪县杉木林分。本研究可以为杉木经营数表的修订或更新提供理论依据。

摘  要:
In this paper the data of 89 sample trees of Cunninghamia lanceolata were used to establish the growth equations of Cunninghamia lanceolata in Jixi County and the data were analyzed. The results showed that the growth equations of the tree height, DBH and volume could be simulated with Logistic equations. The final felling age of Cunninghamia lanceolata plantations in Jixi County could be set at the age of 40. The current one-way volume table of Cunninghamia lanceolata isn't suitable for the stands in Jixi County. The study could provide theoretical basis for revising and updating the management numerical tables of Cunninghamia lanceolata.
