摘要/Abstract

摘要： 对长白落叶松林木生长过程进行了分析,研究表明:人工长白落叶松胸径的连年生长量的峰值出现在16～19a,平均生长量的峰值出现在8～10a,二者在16～18a时相交;树高的连年生长量在14～17a时达到生长高峰,在18～20a时与平均生长量相交;落叶松材积的连年生长量在25～30a时出现其最大值,之后逐年下降,预计与平均生长量在28～33a时相交,可以在18a左右考虑对人工长白落叶松林进行抚育间伐,结合当地的经营目标考虑在28～33a左右进行主伐。同时,研究结果显示:随着径阶的增大,林木胸径、树高和材积的生长规律都基本趋于正常稳定。胸径最优生长方程为:y=1.2546e^0.1247x;树高最优生长方程:y=1.4187e^0.1193x;材积最优生长方程:y=0.00009e^0.3644x。

Abstract: By analyzing stem of Larix olgensis Henry, we analyzed their growing process. So we discussed the time of fostering and logging. It can provide the theory for forest management and harvest in future. The result indicated: the peak value of current annual diameter increment will appear at age 16-19 and that of the average annual increment will appear at age 8-10. The two curves will intersect at age 16-18;The peak value of tree height current annual increment will appear at age 14-17 and after the annual increment's will appear. The two curves will intersect at age18-20; The peak value of volume current annual increment will appear at age 25-30 and that of the annual increment will appear. The two curves will intersect at age 18-20. Then it will descend year by year. The curve of volume current annual increment and annual increment will intersect at age 28-33. Our research shows we can foster Larix olgensis Henry forest by thinning probably at age 18,and harvest and cut trees probably at age 28 to 33 according to the local management targets.Simultaneously,with the diameter classes increasing, the growth rule of tree diameter,tree height and tree volume will approach the general tree growth rule. The superior diameter growth equation is y=1.2546e^0.1247x and the tree height growth equation is y=1.4187e^0.1193x, The tree volume growth equation is y=0.00009e^0.3644x.
