摘  要:
在河南省小秦岭地区设置56个样方进行调查,根据树木异速生长方程,探讨了小秦岭森林乔木地上总生物量随地形因子的变化格局,并研究了该区物种多度最大的华山松生物量随海拔梯度的变化格局。结果表明:(1)地上生物量与海拔因子在统计学上具有显著相关性;(2)乔木地上生物量随海拔上升呈现出先升高后下降的趋势;(3)物种多度最大的华山松的地上生物量随海拔上升呈现逐渐下降的趋势,这与总体乔木地上生物量的变化格局有一定差别,可能是由于华山松生长在较高海拔不占优势;(4)华山松各器官生物量均随海拔先上升后波动性下降,与华山松生物量随海拔变化一致;(5)华山松地上生物量与地下生物量变化趋势一致,其比值在3.1~3.2,随海拔升高呈现出逐渐增高的趋势。

摘  要:
According to the investigation of 56 quadrats in Henan Xiaoqinling,this study explored the change pattern of above-ground biomass of the Xiaoqinling forest trees and studied the change pattern of Pinus armandii biomass through allometric equations. The results showed :( 1) the ground biomass was statistically correlative with the altitude factor;( 2) with altitude rising the tree aboveground biomass showed a downward trend after rising;( 3) armandi pine is the largest species abundance whose aboveground biomass showed a trend of gradual decline with altitude ascent,which is different from the change pattern of tree biomass on the ground,and this may be caused by the disadvantage in high elevation for armandi pine;( 4) with altitude rising the biomass of each organ of armandi pine falls,which is in line with armandi pine biomass changes;( 5) armandi pine aboveground biomass and underground biomass change trend is consistent,and their ratio presents a rising trend between 3. 1 and3. 2 along with the elevation.
