    摘要:

    调查了广东英德石门台自然保护区的植被,并进行群落分析,石门台自然保护区的森林植被以热带亚热带的代表性科属为主,优势科包括壳斗科、山茶科、樟科、杜英科、木兰科、鼠刺科、交让木科、金缕梅科、冬青科、安息香科、杜鹃花科、梧桐科及五列木科等;群落的优势种亦以热带亚热带成分占绝对优势,并多数隶属于这些优势科。依据生态外貌和群落特征,划分了石门台自然保护区的植被类型和群丛。整个保护区包括沟谷季风常绿阔叶林、山地常绿阔叶林、亚热带常绿叶阔叶混交林、山顶矮林、崖壁矮林、亚热带常绿针叶林、亚热带灌丛草坡、亚热带草坡8种植被类型;其中森林植被部分依外貌和优势种又划分为23种群丛。石门台自然保护区多样的植被类型中,具有与独特的地貌类型相适应的特点,有着重大的保护、科研和自然遗产价值,如崖壁矮林,对于研究植物群落的发生和形成以及历史时期的环境变迁均有着重要的意义。

    Abstract:

    Community analysis was made followed by the survey of the vegetation in Shimentai Nature Reserve, northern Guangdong Province's Yingde City. The typical tropical and subtropical families and genera, with Fagaceae, Theaceae, Lauraceae, Elaeocarpaceae, Magnoliaceae, Escalloniaceae, Daphniphyllaceae, Hamamelidaceae, Aquifoliaceae, Styracaceae, Ericaceae, Sterculiaceae, and Pentaphylacaceae being the dominant families, characterize the forest vegetation in Shimentai Nature Reserve. Dominant species are also tropical and subtropical elements, most of which belong to the dominant families. Based on ecological physiognomy and community structure, vegetation of Shimentai Nature Reserve was classified into 8 vegetation-subtypes, i.e., monsoon valley evergreen broadleaved forest, montane evergreen broadleaved forest, subtropical evergreen coniferous-broadleaved forest, montane elfin forest, cliff dwarf scrub, subtropical coniferous forest, subtropical bushy hillside grassland and subtropical bushy mountain slope; and the forest vegetation was further classified into 23 associations. The diverse vegetation, with relevance to the special topography of the protected area, has great value for protection, science and natural heritage. To name only the cliff dwarf scrub, it is significantly important for the research into the initiation and adaptation of plant community and the environmental change in time.
