通过对含有鄂西箬竹的4种植被,即针阔混交林、次生阔叶林、疏灌丛及草甸的样地调查,比较分析了箬竹群落的区系构成,生活型、群落结构及竹类生存状况。20年前的针叶树种的采伐提升了样地的物种多样性,但影响了其下层植物箬竹的生存。疏灌丛比其背景植被草甸含有更高的物种多样性和更多的地下芽植物,然而疏灌丛下的箬竹长势更好。箬竹偏喜于缓坡上具有中等盖度的植被环境。发生于次生阔叶林中的箬竹群体开花预示着在整个神农架亚高山生境的箬竹将在未来的几年内同时开花死亡。这不仅会改变现存竹类立地的区系构成和群落结构,同时也会波及到这一稀有物种的生存问题。
Based on the investigation of the four kinds of vegetation including the coniferous and broadleaf mixed forest, the secondary broadleaf forest, the dredging shrub and the meadow in western Hubei Province, the fauna composition, life form, community Structure and living conditions of bamboo. The harvesting of conifers more than 20 years ago increased the species diversity of the plots, but affected the survival of its lower plant Phyllostachys praecox. Dwarf shrubs have higher species diversity and more underground shoots than their background vegetation meadows, however, the shrubs under the shrubs grow better. Pomfret favors moderate vegetation coverage on gentle slopes. Occurred in the secondary broad-leaved forest in the population of flowering Shizhu indicates that in the Shennongjia sub-alpine habitat bamboo will be in the next few years at the same time flowering death. This will not only change the fauna and community structure of the existing bamboo habitat, but will also affect the survival of this rare species.
