摘要
本文调查了鼎湖山黄果厚壳桂群落，发现在１３００ｍ＾２样地中，有维管束植物１０９种，分属６１科，９１属，以热带属占绝对优势；群落组成种类丰富，结构复杂，外貌终年常绿，植物生活型以高位芽为主，乔木叶子多为单叶并以中型叶为主。这些都反映了本区高温湿润的气候特点。
The Cryptocarya concinna, Lindera chunii community in Dinghu Mountain is one of the types of evergreen broadleaf forest in low subtropical area of China. The specific composition and structural feature in an experimental plot of 1300 m^2 of the community were investigated. The community can be divided into arbor layer including 3 sublayers, shrub layer and herb layer clearly, the tallest tree was 21 m high. In the plot there were 109 species of vascular plants, belonging to 61 families 91 genera, most of which belong to tropical genera. There were 42 species of plants in arbor layer, 30 species in shrub layer and 21 species in herb layer as well as 12 species of liana and 4 species of epiphytes in the plot. It is such a community with complex structure and species diversity. The physiognomy of the community is evergreen all the year round. The life form of plant in the community is phaenerophytes, no cryptophyte, with simple leaf and mesophylls for most trees. Those reflect the climatic characteristics of high temperature and humidity in low subtropical area.
