摘要
基于野外样方调查,分析了南岭国家级自然保护区海拔400～500 m的低山常绿阔叶林群落结构特征和植物多样性。结果表明,样方内分布有乔木59种,分属于30个科;优势种类包括胡氏青冈、甜槠、桂花、猴欢喜、红背栲、山杜英、鹿角栲、檵木、白锥、皂荚等;以物种多度为定量指标计算各群落相似性为0～0.61,相邻号样方的群落相似性系数较大;各群落物种丰富度为11～23种,辛普森指数4.97～21.85,香农—威纳指数2.78～4.38;JSP指数0.15～0.66,JSW指数0.77～0.94。
Structural characteristics and species diversity of low hill evergreen broadleaved forest were analyzed based on field survey data between 400 and 500 meter elevation in Nanling National Nature Reserve. The results showed there were 59 tree species occurred in the survey plots, belonging to 30 families. The dominant species included Castanopsis eyrei, Cyclobalanopsis hui, Castanopsis fargesii, Castanopsis lamontii, Sloanea sinensis, Elaeocarpus sylvestris, Gymnocladus chinensis, etc. Community similarities calculated in terms of abundance ranged from 0 to 0.61, Richness ranged from 11 to 23 species, simpson index ranged from 4.97 to 21.85, Shannon-Wiener index ranged from 2.78 to 4.38, JSP index ranged from 0.15 to 0.66 ,Jsw index ranged from 0.77 to 0.94.
