摘要:
麦吊杉群落在贡嘎山东坡海拔2200~2800m之间呈带状分布。本文从群落分布区的自然环境、群落外貌和结构特征,以及种群结构等方面对其进行了研究。归纳出生活型组成特征、麦吊杉种群高度和胸径的生长规律,以及立木级分布特点,分析了群落的垂直结构,最后与北方的暗针叶林作了比较分析,并讨论了群落的动态特点。
Abstract:
Picea brachytyla community,one of the main representative types of the subalpine dark coniferous forests in southwest China,zonally distributes on the east-facing slope of the Gongga Mountains at the altitude of 2200~2800m. Some aspects of the community, such as physiognomy, community structure and population structure.have been studied and compared with those of the boreal dark coniferous forests. The results indicated: (1)The physiognomy of the community, in view ol life-form composition, is not only dominated by the Phanerophytes, among which Meso-phanerophytes and Middle-phanerophytes are rich. but also characterized by Hemicryptophytes, Geophytes, liana and Epiphytess. which indicate that this community is more adaptable to the warm and humid habitat than boreal dark coniferous forests; (2)The dominant population is mainly composed of mature or over-mature trees of Picea brahytyla and presents a decline trend:and (3)the complex structure is distinctively found with a vettical stratification that can be divided into five strata or layers. The tree stratum can be further divided into three sublayers and shrub layer into two sublayers. Some higher individuals of the shrub species enter the 3rd sublayer of the tree stratum.
