| 摘 要： | 根据生物量调查资料，对樟子松人工林生产力与密度的关系，以及樟子松各器官生物量的分配规律做了初步分析。结果表明，樟子松生产力与密度密切相关；６２０￣８２０株／ｈｍ＾２为中龄林的适宜密度；不同年龄阶段各器官生物量分配规律不同。该研究为评价樟子松人工林及其结构与功能提供了依据。 |
| 关 键 词： | 樟子松 生物生产力 密度 林分结构 |

| Abstract: | The relationship between plantation productivity and stand density as well as the distribution law ofthe above ground biomass tbr Pinus sylvestris var. mongolica were preliminarily analyzed. The resultsshowed that the correlation between plantation productivity and stand density was significant, and theoptimum densities ranged from 620 to 820 per hectare for middle-aged plantation of Pinus sylvestris var.mongolica. the biomass distribution law at various growth stages differed from each other. |
| Keywords: | Pinus sylvestris var mongolica Plantation productivity Stand density |
