摘  要:
黄杉是贵州北部地区亚热带喀斯特山地森林生态系统的一个重要组分。本文对贵州北部地区的黄杉群落及种群结构进行了分析,结果表明该黄杉林群落在树种组成上,是由典型的喀斯特树种所形成的针阔混交林,并且在特殊的生境中,黄杉种群有较宽的生态位,黄杉可在乔木层中形成优势种群。黄杉由于其自身的生物生态学特性,在种群分布的格局上,多为集群分布,人为干扰造成的林窗有利于黄杉的天然更新。

摘  要:
Pseudotsuga sinensis is an important composition of tropical karst mountain forest system in north Guizhou Province. The structures of community and population of Pseudotsuga sinensis are studied in the paper. The results showed that Pseudotsuga sinensis forest was the mixed conifer and broadleaf forest composed of typical Karst trees, and Pseudotsuga sinensis had a wide niche to hold a dominated position of tree layers in the special habitat. The distribution patterns of the population presented mainly an aggregated pattern due to its ecological and biological characters. The forest gap by human disturbance make the easy natural regeneration for Pseudotsuga sinensis.
