35年生天然米槠林为福建省建瓯万木林自然保护区的常绿阔叶林类型之一，对其群落学特征及测树学特征调查研究表明：本群落乔木层由21种树种组成，米槠占绝对优势（重要值达147．69）；群落处在缓慢演替之中；林分为较典型的复层异龄混交林，生产力高，蓄积量达531．6m3／hm2，蓄积平均生长量达15．2m3／（hm2·a）；树干生物量达265．8t／hm2，树干生物量平均生长量达7．594t／（hm2·a）．本研究对中亚热带天然阔叶林经营利用技术研究有借鉴作用．
The 35-year-old natural Mianyanglin is one of the evergreen broad-leaved forest types in Jianou Wanmulin Nature Reserve in Fujian Province. The investigation of its community characteristics and tree-finding characteristics shows that the tree layer of the community consists of 21 species of trees, Melaleuca occupy the absolute advantage (important value of 147.69); the community in the slow succession; forest is divided into more typical mixed stratified heterogeneous mixed forest, high productivity, volume of 531.6m3 / hm2, the average volume The biomass of tree trunk reached 265.8t / hm2 and the average growth of trunk biomass reached 7.594t / (hm2 · a). This study can be used as a reference for the research on management and utilization of natural broad-leaved forest in the subtropical region.
