摘    要:指出了灌丛是陆地生态系统的重要组成部分,亚热带亚高山灌丛具有物种组成、分布与形成的特殊规律,研究其结构组成特征对于亚高山生物多样性保护具有重要的意义。对林芝地区亚高山落叶阔叶灌丛进行了实地调查,测定了株高、密度、盖度、冠幅等指标,记录了海拔、地形、经纬度等因子,分析了植物科属组成特点、物种丰富度、物种多样性、重要值等研究灌木群落的结构特征,为林芝地区亚高山落叶阔叶灌丛的合理利用、开发和保护提供理论依据。

关 键 词:西藏林芝  亚高山落叶阔叶灌丛  物种丰富度  物种多样性  重要值

Abstract:Shrub is an important component of the terrestrial ecosystem. The subalpine deciduous broadleaf shrubs have specific regularity in speciation, distribution and formation and the research on their structure characteristics is of great significance to protect the subalpine biodiversity. This study investigates the subalpine deciduous broadleaf shrubs distributed in Linzhi Area, Tibet, determines the height, density, coverage of the plant, and takes noted of the elevation, landform, longitude and latitude of the plot sites as well. In addition, it studies the species diversity, richness, and important value index to evaluate the structure characteristics of the shrubs, so as to provide a theoretical basis for the reasonable exploitation and reservation of the subalpine deciduous broadleaf shrubs in Linzhi Area.
Keywords:Linzhi of Tibet  subalpine deciduous broadleaf shrubs  species richness  species diversity  important value
