摘 要 ：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。

Abstract:The relation of the cones‘ biomass of Pinus tabulaeformis to site conditions and factors of mensuration was studied by measuring the cones‘ biomass of average tree of Pinus tabulaeformis plantation under the different site conditions. The results of our study have showed that the cones‘ bicmass of Pinus tabulaeformis is most on the ridge and the southern slope of a mountain, moderate on its northern slope and least in its valley. There is a positive correlation between the cones‘ biomass of Pinus tabulaefor...
