摘要：在深圳市羊台山森林公园,选择有代表性的近自然次生林建立1hm2的固定样地,通过群落学调查、应用聚类分析和生态位特征分析相结合的方法,研究次生林树种组成与垂直结构。结果表明:羊台山1hm2样地有乔木树种72种,隶属34科57属,其中大型木质藤本6种,优势种有浙江润楠、水团花、中华楠、罗伞树、九节、中华卫矛、三花冬青、簕欓花椒、杨桐、红车等,形成以浙江润楠为建群种的单优势种群落(重要值24.85%);浙江润楠形成林冠层,其垂直空间生态位宽度值最大,仅与中华楠和水团花的生态位重叠值在0.78以上。整个群落物种组成较为丰富,结构趋于稳定,空间格局上主要树种的垂直分布合理,具有南亚热带季风常绿阔叶林中生性顶级群落的基本特征,在羊台山森林公园低山区域分布广泛。
Suburban scenic forest plays an important role in the urban ecological security and ecological landscape. Understanding their species composition and vertical structure can provide technical support for scenic beauty cultivation and recreation cultivation of secondary forest. We collect data by investigating a representative near-natural secondary forest from 1 hm2 permanent plots in Mt.Yangtai, Shenzhen. We apply two methods cluster analysis and niche characteristics to study plant species composition and community vertical structure. The results show that the permanent plots have 72 tree species which belong to 34 families and 57 genera including 6 large woody vines in the permanent plots. The dominant families are Lauraceae, Rubiaceae, Myrsinaceae, Celastraceae, Aquifoliaceae, Rutaceae, Theaceae, Myrtaceae; the dominant species are Machilus chekiangensis, Adina pilulifera, Machilus chinensis, Ardisia quinquegona, Psychotria asiatica, Euonymus nitidu, Ilex triflora, Zanthoxylum avicennae, Adinandra millettii, Syzygium hancei and so on. The near-natural secondary forest is made of single dominant species community M.chekiangensis （importance value is 24.85 %）. M.chekiangensis forms the canopy layer, of which the vertical spatial niche breadth value is the largest and the niche overlap value versus A.pilulifera and versus M.chinensis is above 0.78. It is found that M.chekiangensis community has relatively rich species, of which species composition and structure is stable, and the main species has a relatively reasonable vertical spatial distribution pattern. It indicates that M.chekiangensis community is a climax community in the zonal vegetation of south sub-tropic evergreen forest, which appears in an extensive distribution in the low hills of Mt.Yangtai in Shenzhen.
