| 摘 要： | 在马尾松Pinus massoniana林林下分别套种拉氏栲Castanopsis lamontii，青栲Cyclobalanopsis myrsinaefolia，格氏栲Castanopsis kawakamii和苦槠Castonopsis sclerophylla，形成针阔混交复层林。对该混交模式16年生的不同阔叶树种林分生长过程进行研究，结果表明：4种阔叶树种的树高连年生长量的高峰值分别出现在第14年，第4年，第6年，第12年。而胸径连年生长量高峰值分别出现在第10年，第8年，第10年，第8年。不同阔叶树种的林分生长存在明显差异，表现为格氏栲＞青栲＞苦槠＞拉氏栲。在混交林模式中，林间套种苦槠更有利马尾松的生长，种间关系更为协调，马尾松平均树高为23.1 m，平均胸径为31.1 cm，单株材积可达0.536 m3。图4表1参7

| Abstract: | Interplanting broad-leaved tree species under the Pinus massoniana forest(masson pine,which planted in 1960),respectively Castanopsis lamontii,Cyclobalanopsis myrsinaefolia,Castanopsis kawakamii,and Castanopsis sclerophylla in 1984,coniferous and broad-leaved mixed multiple layers were formed.The tree height and diameter at breast height(DBH) of the four broad-leaved tree species were measured every two years from the forth year.In the 16th year(2000),masson pine’s tree height,DBH,and timber volume were measured.The results showed that: current annual increment in tree height reached maximum,Castanopsi slamontii in the 14th year,Cyclobalanopsis myrsinaefolia in the 4th year,Castanopsis kawakamii in the 6th year,and Castanopsis sclerophylla in the 12th year;the DBH annual increment reach peak respectively in the 10th,8th,10th,and 8th year in order.Different broad-leaved tree species showed different growth rates,which in order of Castanopsis kawakamii > Cyclobalanopsis myrsinaefolia > Castanopsis sclerophylla > Castanopsis lamontii.Interplanting Castanopsis sclerophylla is more beneficial to the growth of masson pine.In the 16th year,masson pine had 23.1 m height,31.1 cm DBH,and 0.536 m3 timber volume. |
