摘要
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 Castanopsis carlesii forest is one of forest types in Wanmulin Nature Reserve. The results of study on the features of forest community indicate: 1) The tree layer of the forest is consisted of 21 tree species and dominated by Castanopsis carlesii. 2) The stand structure is a more typical uneven-aged forest,3) The stand has high productivity, with its volume as 531. 6m3/hm2, its average volume inrement as 15. 2m3/ (hm2. a)stem biomass as 265. 8t/hm2 and its increment as 7. 594t/ (hm2. a). The results is good for the study in the natural broad-leaved forest management in mid-subtropical region.
