摘　　要： 论述了森林生物量的发展历史、概念和研究方法,总结了森林经营、混交、造林密度等对生物量的影响:连栽的林分生物量逐代下降;林分间伐后,林分总的生物量有所降低,但是提高了林分质量;合理混交有利于提高林分总生物量;一定密度范围内林分生物量随林分密度的增加而增加,最终,不同密度林分的生物量接近一个常数 最后。 Development history, conception and research method of forest biomass were explained. The impacts of forest management, mixed plantation, tree density were summarized: the forest biomass of successive plantation decreases generation after generation; forest is intermediately cut, its total biomass will be decreased, but the forest quality will be raised; mixed plantation is favorable for total forest biomass; forest biomass increases with increasing forest density in a certain density range, and the biomasses of different density forests will finally be closed to a constant with the forests sufficiently grow. Finally, authors pointed out the research tendency of forest biomass.
