摘要:
利用相容性生物量模型对人工长白落叶松林生物量进行计算,分析了间伐对林分 总生物 量、树干生物量、树枝生物量和树叶生物量的影响。结果表明:间伐林分在间伐后总生物 量明显低 于未间伐林分的总生物量;经过一段时间的生长,间伐林分的生物量渐近于未间伐林分生 物量;间 伐林分的树枝和树干生物量比未间伐林分大,间伐强度在弱度时树枝和树干生物量占总 生物量比 率较大;未间伐林分树叶生物量占总生物量比率比间伐林分大。
Abstract:
The biomass of Larix olgensis plantation is calculated using compatible biomass model, the bioˉ mass of total tree, bole, branches and foliage is analyzed. The re sults indicated that the biomass of stands after thinning is obviously less than that of control in initial s tages, but the biomass of stands thinned will approach to control after some period of growth. The biomass of b ole and branch from stands thinned were bigger than that of control, the rate of biomass of bole and br anch in total biomass of light thinning is bigˉ ger than that of control. While the rate of biomass of bole and b ranch to total biomass in light thinning is bigger than orther thinning strength. For the control, the rate o f biomass of the foliage to the total is bigˉ ger than that of stands thinned.
