辽西北沙地樟子松人工林立地指数表及建筑材出材量表编制

为了提高樟子松的栽培和经营水平，编制辽西北地区的樟子松立地指数表和出材量表。在辽西北地区，把樟子松以 30 a为标准年龄，按照树高划分为 8～12共 5个立地指数级，并编制立地指数表；参考林业技术规程，划分长度 2.5 m、小头去皮直径 12 cm以上为建筑材，并根据材积比方程，编制了建筑材出材量表；经检验文中数表适用于辽西北不同立地条件沙地，可以为当地樟子松建筑材经营提供参考。

To enhance the cultivation and management of Pinus sylvestris var. mongolica, site index tables and timber yield tables were developed for this species in Northwest Liaoning. Taking 30 years as the standard age, five site index classes ranging from 8 to 12 were divided based on tree height, and the corresponding site index table was compiled. Referring to forestry technical regulations, construction timber was defined as logs with a length of 2.5 m and a debarked diameter at the small end of more than 12 cm. Subsequently, the construction timber yield table was compiled based on the volume ratio equation. The tables in this paper were verified to be applicable to sandy lands with various site conditions in Northwest Liaoning, and can provide references for the construction timber management of local Pinus sylvestris var. mongolica.
