- 摘要:
- 以百里杜鹃自然保护区淡紫杜鹃为研究对象,采用野外植物群落调研方法,在保护区内设置1个10 m×20 m的样地,研究了淡紫杜鹃群落结构和多样性特征,以期为百里杜鹃有效保护种质资源和生物多样性等提供参考依据。结果表明:1)样地内共有维管束植物24科32属47种,群落中植物优势科为蔷薇科和杜鹃花科;只出现1个种的科和属较多;2)群落垂直结构为乔木层、灌木层和草本层3个层次,群落乔木层植物以迷人杜鹃为优势种,白栎为亚优势种,灌木层中淡紫杜鹃占优势地位。
- Abstract:
- Taking the Baili Rhododendron nature reserve as an example to study the the community biodiversity of Rhododendron lilacinum.The method of field plant community investigations was used.A sample plot with the area of 10 m×20 m was investigated to study the community structure and diversity characteristics,in order to provide a referencefor the effective protection of germplasm resources and biodiversity of Baili Rhododendron.The results showed that,1) there were 47 species of vascular plants belong to 24 families and 32 genera,and the dominant families in the community were Rosaceae and Ericaceae.Many families and genera had only one species.2) The vertical structure of the community consists of three layers,arborous layer,shrub layer and herb layer.R.agastum and Quercus fabriare were the dominant species and sub-dominant species in the arborous layer,the R.lilacinum was the dominant species in the shrub layer.
