在线路调查和样方凋查材料的基础上分析了粤北八宝山自然保护区森林群落的组成和结构特征。八宝山森林群落外貌终年常绿,群落的区系组成以亚热带的科属为主,优势科为壳斗科、山茶科、樟科、木兰科、金缕梅科、安息香科、五列本科、杜英科、杜鹃花科、松科、冬青科以及交让本科。优势种亦大部分由这些科的种类组成。群落中胸径≥2cm的个体密度为3377株/hm2,平均距离为1.62m。群落的垂直分化比较明显,乔木层一般可分为2—3亚层。第1亚层高16—22m;第2亚层高10—16m;第3亚层高5—10m。群落缺乏板根现象和大型木质藤本,附生植物也不发达,表现出中亚热带森林的特色。
The composition and structure of forest community in Babaoshan Natural Reserve in northern Guangdong were analyzed based on the line survey and the material of the withered plot. The fauna of Babaoshan forest community is evergreen all year round. The fauna of the community is dominated by subtropical families, and the dominant families are Fagaceae, Camellia, Lauraceae, Magnoliaceae, Hamamelis, Benzoin, Pentaphyllum, , Rhododendron, Pinaceae, Holly Branch and transfer to undergraduate. The dominant species are also mostly composed of the species of these families. The density of individuals with DBH≥2cm was 3377 plants / hm2 and the average distance was 1.62m. Vertical differentiation of the community is more obvious, the tree layer can be divided into 2-3 sub-layer. The first sub-layer is 16-22m high; the second sub-layer is 10-16m high; the third sub-layer is 5-10m high. Lack of root community and large-scale woody vine, epiphytic also underdeveloped, showing the characteristics of the subtropical forest.
