根据广州罗岗村这次生常绿阔叶林的调查结果,分析了该群落的组成结构特征在1200m2的样地里有维管束植物引种,隶属于40科65属其区系特点具有从热带向亚热带过渡的性质该群落分为乔木层(3亚层)、灌木层及草本层等层次乔、灌层种类较多,主要以往粟(Caastanopsischinensis)、黄桐(Endospermumchinense)和黄果厚壳桂(CryptocargaconcinnaHance)等种类组成,草本展种类少.本群落以中、小高位芽植物占优势,缺乏大高位芽、隐芽和一年生植物叶型以中型叶为主群落的大部分优势种的种群分布格局是随机分布的优势种群的立木结构分析表明,本群落处于进展演替它与30a前比较有较大的变化乔木层原优势种黄桐、猴耳环(Pithecellobiumclyperia)、亮叶肉实(Sarcospermalaurinum)等被锥粟、刺栲(Castanopsishystrix)等替代.草本层原以禾本科植物为主,现已发展为原生性较强的龙船花(Ixorachinensis)、九节(Psychotriarubra)等种类
According to the survey results of the evergreen broad-leaved forest in Luogang Village, Guangzhou, the compositional characteristics of this community were analyzed. The introduction of vascular plants in a sample plot of 1,200 m 2, belonging to 40 genera and 65 genera in 40 families, The nature of the transition to the subtropical community of the community is divided into the arbor layer (3 sub), shrub layer and herb layer Joe, irrigation more types, mainly in the past millet (Caastanopsischinensis), Huangtong (Endospermumchinense) and yellow carapace (CryptocargaconcinnaHance ) And other species, herbs show less. The community dominated by medium and small high bud plants, the population distribution pattern of most dominant species lacking large high buds, hidden buds and annual leaves with middle leaves was the stochastically distributed stand structure analysis. , The community is in the process of succession and it has a greater change compared with that of 30 years ago. The original trees of the tree layer, Huangtong, Pithacellobium clyperia and Sarcospermalaurinum, were replaced by Cone millet and Castanopsishystrix. Herbaceous plants originally dominated by gramineous plants have now developed into more protozoa species of Ixorachinensis, nine (Psychotriarubra) and other species
