摘 要 樟子松是遼寧西部地區(qū)重要造林樹種。為構建沙地樟子松削度預測模型，通過對彰武縣42株樟子松解析木數(shù)據(jù)構建了削度方程，最終得出修正后的Kozak2004式為彰武地區(qū)樟子松最優(yōu)的削度方程模型。關鍵詞 削度方程；樟子松；解析木；模型中圖分類號：S791.253.06       文獻標識碼：A   doi：10.13601/j.issn.1005-5215.2024.02.008

Study on the Taper Equation of Pinus sylvestris var. mongolica in Zhangwu County

Abstract Pinus sylvestris var. mongolica is an important afforestation tree species in western Liaoning. In order to construct the prediction model of the taper of Pinus sylvestris var. mongolica in sandy land，the taper equation was constructed based on the data of 42 parse trees of Pinus sylvestris var. mongolica in Zhangwu County. Finally，it is concluded that the modified Kozak2004 equation was the optimal taper equation model of Pinus sylvestris var. mongolica in Zhangwu area.

Key words taper equation;Pinus sylvestris var. mongolica;parse tree;model

樹干的形狀即干形，是反映樹干外部形態(tài)的重要指標，同樣也是評價干材價值的重要依據(jù)之一，因此可以通過削度方程表示干形的變化[1，2]。（剩余3585字）
