摘　　要：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 improve the cultivation and management level of Pinus sylvestris var. mongolica plantation, the site index table and timber assortment table of P. sylvestris var. mongolica plantation in northwest of Liaoning were compiled. In the northwest area of Liaoning, 30 a P. sylvestris var. mongolica plantations were selected as standard study objects, which were divided into 5 site levels according to the tree height,then the site index table was compiled. According to the forestry technical regulations, the woods with length more than 2.5 m and small end diameter over 12 cm were classified as building timbers. According to the volume ratio equation, the timber assortment table was developed. Through practical verification, those tables in this paper were applicable under different site conditions in sandy lands of northwest Liaoning province, which would provide reference for local timber management of P. sylvestris var. mongolica.
