摘要
采用Raunkiner生活型分类系统 ,对缙云山常绿阔叶林不同演替阶段植物的生活型进行统计 ,编制了生活型谱 ,并与其他亚热带地区常绿阔叶林相比较 .结果表明 ,缙云山植被属典型的中亚热带常绿阔叶林植被 ,高位芽植物占绝对优势 ,达 80 %以上 ,其中小高位芽植物最多 ,中高位芽与矮高位芽植物次之 ,藤本植物较丰富 .缙云山不同演替阶段的植物的生活型谱不同 .随着进展演替阶段的逐渐更替 ,高位芽植物的比例呈递增趋势 ,地面芽植物、地下芽植物成分有所减少 .
The life form of plant communities in different succession stages in Jinyun Mountain was studied and the life form spectrum was established. The results showed that according to the characters of life form of plant communities,the vegetation in Jinyun Mountain belonged to typical subtropical evergreen broad leaved forest vegetation. Evergreen phaenerophytes were absolutely dominant in the life form spectrum and its quantity accounted for more than 80%. Among phaenerophyte,quantity of microphanerophyte was the most,and quantities of mesophanerophtye and nanophanerophyte were less. Different successions had different life form spectra. With the development of succession,the percentage of phaenerophytes increased,and other life forms decreased correspon dingly. According to the development of life form and comparative analysis of environmental factors in different succession stages,coniferous species would be replaced by evergreen phaenerophytes.
