摘    要:选择5株28年生红锥(Castanopsis hystrix)人工林平均木进行树干解析,对其去皮胸径、树高、单株材积、形数生长规律进行分析。并采用6种林木生长经验模型对去皮胸径、树高、单株材积进行回归分析,选取合适的生长模型。结果表明:28年生红锥在第8-15年为速生期。胸径在第8-15年处于生长高峰期,连年生长量范围为1.01-1.11 cm/a;树高的连年生长量在第6-15年间处于较高的阶段,连年生长量范围为1.02-1.16 m/a;单株材积平均生长量和连年生长量增长幅度在第6-17年之间和第24-28年间较大,连年生长量在第14年后均大于0.01 m^3/a。坎派兹(Compertz)方程对去皮胸径的拟合效果最好,韦布尔(Weibull)方程对树高的拟合效果最好,苏玛克(Schumacher)方程对单株材积的拟合效果最好。

Abstract:Choosing 5 average trees from the 28-year-old Castanopsis hystrix plantation,tem analysis was done to analyze the peeling DBH,tree height,individual volume and form factor growth rhythm.The regression analysis of peeling DBH,tree height and individual volume was made by six kinds of tree growth model,then the suitable growth model was chosen.The results showed that the fast-growing period of 28-year-old C.hystrix was from the 8th year to the 15 th year,the same as peeling DBH with the range of annual increment 1.01 - 1.11 cm /a.The annual increment of tree height was in high phases from the 6th year to the 15 th year with the range 1.02 - 1.16 m /a.The average increment and the annual increment of individual volume had larger increasing range from the 6th year to the 17 th year and from the 24 th year to the 28 th year.The annual increment was all more than 0.01 m^3/a after the 14 th year.The Compertz equation had the best fitting effect on the peeling DBH.The Weibull equation had the best fitting effect on the tree height.The Schumacher equation had the best fitting effect on the individual volume.
Keywords:Castanopsis hystrix  growth rhythm  stem analysis  growth model
