摘要: 应用年轮分析法研究马尾松栽种的第1代和自然更新代的动态。结果表明,本区域马尾松第1代在贫瘠土壤上能正常生长,并在成熟期有较高的生长量,因此不失为较好的造林绿化的先锋树种。从经济利用的角度出发,应在生长量高峰期后采伐最为合理,在本区域采伐期可选择在树龄40年左右。但马尾松的更新代严重退化,表明本区域在土地利用上不能连续栽种马尾松,最佳方式是在35年林龄左右进行林分改造。

关键词: 马尾松, 第1代, 更新代, 生长动态

Abstract: In this paper, the growth dynamics of first generation and regeneration of Pinus massoniana is compared by tree ring analysis.The results show that the first generation can growwell on poor barren land.The growth peak is at 35-40 years.The individuals of regeneration degenerated seriously, which implies that continuous plantation of poly-generationis not a reasonable management, and stand-remaking should be carried out when the age of forest is about 35 years old.

Key words: Pinus massoniana, First generation, Regeneration, Growth dynamics
