本文是用实测油松人工林平均木球果生物量的方法,来研究不同立地条件、测树学因子与油松人工林球果生物量的关系。结果表明,油松球果生物量以山脊、阳坡最多,阴坡次之,山洼最少;油松球果生物量与林木生长级之间呈正相关;在单株林木的树冠部位上是以上、中部的球果生物量最多,下部最少,向阳面显著多于背阴面。胸径、树高与球果生物量之间呈直线正相关,并推导出预测油松球果生物量的回归方程。
In this paper, the average biomass of Pinus tabulaeformis plantations was used to study the relationship between different site conditions, tree-finding factors and biomass of Pinus tabulaeformis plantations. The results showed that the biomass of Pinus tabulaeformis was highest in ridge, sunny slope, followed by shady slope, and lowest in mountain depression. The biomass of Pinus tabulaeformis was positively correlated with the growth of forest, The coniferous biomass was highest in the middle with the least in the lower part, and significantly more in the sunny side than in the shady side. There was a linear correlation between DBH, tree height and cone biomass, and the regression equation for predicting the biomass of Pinus tabulaeformis was derived.
