天然长白松生物量的研究

天然长白松仅见于长白山北坡海拔630～1 400 m之间,是我国特有的松科松属植物,因其特殊的分类地位,被列为国家Ⅲ级珍稀濒危树种,而受到广泛关注。本文利用多元分析方法,对第一代天然长白松的生产结构和生物量进行研究。给出长白松生物量估测的回归模型及估测参数,指出生物量在长白松天然林中的分配规律,为经营长白山这一特有的种群提供理论依据。

Study of Biomass of Natural Pinus syivestris var. syivesriformis

The natural Pinus sylvestris var.sylvesriformis is only found on the north slope of Changbai Mountains between the elevations of 630-1400 m.It＇s one of the Chinese special species belonged to Pinaceae Pinus.Because of the special classification and status,it is classified as a National Ⅲ rare and endangered species,which receives widespread attention.By using multivariate analysis method,the production structure and biomass of the first generation natural Pinus sylvestris var.sylvesriformis were studied in this paper.The regression models of biomass estimation and estimating parameters were given,and the distribution law of Pinus sylvestris var.sylvesriformis biomass in the natural forest was pointed out,which provided the theoretical basis for protecting and managing the unique species in Changbai Mountain.
