广东南岭秋色叶植物群落结构特点及其生态园林应用

Characteristics of Community Structure of Fall Color Plants in Nanling of Guangdong and Its Application in Ecological Garden

通过典型样地法,调查广东南岭秋色叶植物群落,结果表明:该群落共有维管植物58科81属139种,其中乔木层有33科52属87种,物种多样性较大,以山茶科、壳斗科、樟科植物为主,建群种为水青冈(重要值最大),为温带属,优势种多为热带属;乔木层径级分布大致成"L"型,幼树占相当大的比例;垂直结构明显,乔木层可分3个亚层;季相变化明显,秋叶景象壮观。

The fall color plants community of Nanling, Guangdong Province was investigated by plot method. The results showed that： There are 139 species of vascular plants belonging to 81 genera of 58 families. The arbor layer includes 87 species, belonging to 52 genera of 33 families with high biodi- versity. The typical families of the flora are Theaceae, Fagaceae and Lauraceae. Fagus longipetiolata, a temperate genus, is the constructive species with the largest important value, whereas the dominant species mostly belong to tropical genera. The L-shaped diameter-classes curve of arbor layer trees indi- cates a large population of young trees. The vertical structure of the fall color plants community is ob- vious. The arbor layer could be divided into 3 sub-layers. The seasonal change is obvious and the fall color scene is spectacular.
