| 摘 要： | 选择安徽亚热带地区的肖坑小流域，对该地实施封山育林后植被恢复的情况、生产力水平作了初步评价。其中，甜槠群落的平均生物量为120.165 t/hm2，苦槠群落的为96.168 t/hm2，青冈群落的为72.73 t/hm2，绵槠群落的为80.416 t/hm2。上述群落中生物量在不同径阶的分配呈正态分布，且主要集中在胸径12~24 cm的树木中。群体的主干生物量均随树木高度的增加而逐渐减小，并且地上部分生物量在2~8 m处较高。主要群落生物量的动态分析表明，该地林分大多在20~50 a。

| Abstract: | Xiaokeng small basin,which located in the subtropical zone of Anhui,was selected as the study area.We made a primary assessment on vegetation recovery and productivity level of forest since it has been protected.Castanopsis eyrei,Castanopsis sclerophylla,Cyclobalanopsis glauca and Lithocarpus harlandii were appraised.The average community biomass of the above 4 species was 120.165,96.168,72.73 and 80.416 t/hm2 respectively.In the above communities,the biomass distribution of different DBH class followed nor... |
