采用配对样地法,以不同栽植代数（1、2代）、不同发育阶段（8、15、18、20 a）的马尾松人工林为对象,对1、2代马尾松人工林林分树高、胸径、单株材积及蓄积量生长进行比较分析。结果表明：马尾松连栽后,林分平均胸径、平均树高、单株材积和林分蓄积等指标总体表现为2代好于1代,2代较1代总体分别上升0.61%、3.17%、3.85%和23.82%,但差异均不显著。马尾松连栽并未导致林分平均胸径、平均树高、单株材积及蓄积量生长出现下降趋势,林分生产力水平不但没下降,反而还有一定程度的提高。

In this study,the growth characteristics of Pinus massoniana were compared in the 1st and 2nd generations of Pinus massoniana plantations through the pair method with different generations（1,2） and ages（8,15,18,and 20 a）.The results were as follows： after successive rotation of Pinus massoniana,the values of average diameter at breast height,average height,single volume and stand volume in the 2nd generation were higher than that in the 1st generation,and the values increased 0.61%,3.17%,3.85% and 23.82%,respectively,but the differences between the 1st and 2nd generations were not significant.Successive rotation of Pinus massoniana has not deduced the values of average DBH,average height,single volume and stand volume and the stand productivity were improved to some extent.
