选择闽北较有代表性的建瓯万木林自然保护区封禁保护达６００多年的中亚热带森林，包括常绿阔叶林、马尾松林及与万木林相连的七道村罗浮栲次生林作为研究对象，据群落中各组成成分的重要值对群落进行聚类分析、主成分分析及演替分析。结果表明，该地区典型的演替系列前期主要为马尾松群落（山脊较瘠薄处）和栲类次生林（采伐迹地），中后期为米槠林和丝栗栲林。地带性植被为栲类常绿阔叶林。局部水热条件较好的立地可演替到后顶极群落———以樟科、浙江桂等为主的樟类阔叶林，而细柄阿丁枫群落在该区为过渡性群落。笔者还对观光木群落的产生和演替趋势进行了初步研究。
In this paper, we selected subtropical forests of more than 600 years, including evergreen broad-leaved forests, Pinus massoniana forests, The importance of each component in the community cluster analysis, principal component analysis and succession analysis. The results showed that the typical successional series in this area were mainly Pinus massoniana community (barren ridge) and 栲 secondary forest (deforestation) in the early stage and Megalotaxis ostreatus and Castanopsis kawakamii forest in the middle and late stages. Zonal vegetation as a kind of evergreen broad-leaved forest. The site with better local hydrothermal conditions can be replaced by the climax community - the camphor broadleaf forest dominated by laccase and zhejiang cinnamon, while the community of small stem Arbutin is a transitional community. The author also made a preliminary study on the generation and succession of sightseeing woody communities.
