| 摘要: |
| 基于野外样方调查数据分析了南岭国家级自然保护区海拔400-500米之间的低山常绿阔叶林群落结构特征和物种多样性。结果表明，该林分样方内出现的乔木共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的各群落相似性最低为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种之间，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。 |

| Abstract: |
| 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 suvey 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 0-0.61; Richness ranged from 11-23 species;simpson index ranged from 4.97 to 21.85,Shannon-Wiener index ranged from 2.78 to 4.08, Jsp index ranged from 0.15 to 0.66,Jsw index ranged from 0.77 to 0.94 . |
