摘  要：
以不同密度调控(4 950株·hm~(-2)、1 800株·hm~(-2)、1 160株·hm~(-2))下的云杉人工林为研究对象,通过典型抽样法和模型模拟法获取和分析了不同密度云杉人工林林分的生物量,乔木各器官生物量,乔、灌、草生物多样性等指标,研究了密度调控对川西亚高山云杉人工林生物量、生物多样性的影响。结果表明,密度调控不但提高了川西亚高山云杉人工林的林木生物量,还提高了其以乔木生物量为主的林分生物量。1 160株·hm~(-2)的密度水平较另外2种密度更能提高云杉人工林的林分生物量。同时,密度调控提高了干生物量的分配比例。此外,密度调控还显著地提高了林下灌草的生物多样性。

摘  要：
In this paper,studies were made of the total biomass,organ biomass of main trees and diversity of tree layer,shrub layer and grass layer from different density adjusting modes( 4 950 trees per hectare,1 800 trees per hectare and 1 160 trees per hectare),and analysis was made of effects of density adjusting on biomass and biodiversity of artificial Picea asperata forest through representative sampling and modeling. The result showed that both individual biomass and stand biomass that mainly came from tree biomass increased significantly after density adjusting 6 years later. There were more stand biomass with 1 160 tree per hectare than those with other density. Meanwhile,density adjusting promoted significantly trunk biomass proportion. Finally,density adjusting increased the diversity of shrub and grass under forest significantly.
