| 摘 要： | 28年生人工油松林标准地设置在西山海拔300一350米的南坡与北坡山地。试用了多种数学模型预测人工林乔木层的生物量，应用w(树干)=2.372(D2H)0.664， w(枝条)=1.317(D2H)0.992，w(叶子)=1.417(D2H)0.833和w(根系)=1.593(D2H)0.757幂函数方程，分别获得树干、枝条、叶子和根系的生物量。南、北坡油松林乔木层生物量分别为29.13吨／公顷和42.46吨／公顷。用直接收获法测得不同坡向油松林的灌木层和草本层生物量的季节动态，以8月份生物量计，南、北坡灌木层生物量为8.05吨／公顷和5.78吨／公顷，草本层为0.74吨／公顷和0.77吨／公顷。南，北坡油松林的总生物量为38.08吨／公顷和48.68吨／公顷。

| Abstract: | The sample plots of 28-aged Pine plantation (Pinus tabulaeformis) were located on the southern and northern slope of Xishan (West Mountain) at an altitude of 300--350m. By using power equations W(stem weight)= 2.372 (D2H)0.664,W(branches weight)= 1.317 (D2H)0.992,W(leaves weight) = 1.417(D2H)0.833, and W(roots weight)= 1.593 (D2H)0.757, the biomass of stems, branches, leaves and roots was obtained. The biomass of tree layer of Pine plantation on the southern and northern slope was 29.13t/ha, 42.46t/ha respectively. By using direct harvest method to estimate the seasonal dynamic of shrub and herbaceous layers in Pine plantation, the biomass of the shrub layer on the southern and northern slope in August was 8.05t /ha and 5.78t/ha, the biomass of the herbaceous layer was 0.74t/ha and 0.77t/ha respectively. The total biomass of the Pine plantation on southern and northern slope was 38.08t/ha and 48.68t/ha respectively. |
