摘要:
采用典型样方调查的方法，研究了通天河国家森林公园锐齿栎群落物种组成及群落结构。结果表明：（1）该锐齿栎群落共有植物108种，隶属于46科84属，蕨类植物1科1属，裸子植物1科2属，被子植物44科81属；（2）植物基本上可以分为5个层次，草本层、灌木层、乔木第1亚层、乔木第2亚层和乔木第3亚层，草本层优势种是四叶葎、和尚菜、披针叶茜草，灌木层优势种是悬钩子、卫矛、绣线菊，乔木第一亚层优势种是锐齿栎、云杉和板栗，乔木第二亚层优势种是锐齿栎，乔木第三亚层优势种是锐齿栎；（3）锐齿栎种群径级分布基本上属于多峰型，种群的年龄结构表现为增长型，说明该地区锐齿栎种群处于增长阶段。
Abstract:
Based on the plot investigation, the species composition and structural characteristics of Quercus aliena community in national forest park of Tongtianhe river were studied. The results showed that: (1) Totally, 108 species of plants were recorded in Quercus aliena community, and they were distributed into 46 families and 84 genera. That concluded 1 family, 1 genus pteridophyte, 1 family, 2 genera gymnosperms and 44 families, 81 genera angiosperms; (2) Plant community can be divided into five layers, which are herb layer, shrub layer, tree first sublayer, second sublayer and third sublayer.The dominant species of herb layer are Galium bungei, Adenocaulon himalaicum and Rubia lanceolata. The dominant species of shrub layer are Rubus corchorifolius, Euonymus alatus and Spiraea salicifolia. The dominant species of tree first sublayer are Quercus aliena, Picea asperata and Spiraea salicifolia. The dominant species of second sublayer and third sublayer is Quercus aliena;(3) The DBH class structure of Quercus aliena community is sporadic. The age structure of this species group is growth-oriented, which means Quercus aliena community is at growth stage in this national forest park.
