摘要
对日本落叶松人工林生物量的调查研究表明，区域、立地、密度、林龄对落叶松生物量及器官分配均有较大影响。辽东地区的日本落叶松林生物量和树干生物量显著高于辽北、辽南和辽西地区；林分的生物量随立地条件的改善而加大；各地位级林分的生物量均随年龄的增加而呈上升的趋势；密度最适林分生物量最大；活地被物生物量与枯枝落叶层的现存量均以近熟林较高。
This research indicated that region,site,density,and age had great influences to the
biomass of Larix kampferi plantation and its distribution. The biomass of a plantation in
Eastern Liaoning was remarkably higher than those of plantations in Northerm, Southern, and
Western Liaoning. Forests in sites with higher improvement had higher biomass, and the older
the forest was, the higher the biomass. The biggest biomass existed in forest with optimum
density. And the biomass of living ground cover and that of leaf litter in the forest near mature
were the largest.
