| 摘 要： | 通过对浙江天童地区不同生境中的小叶青冈种群的结构特征和更新进行研究。结果表明:①小叶青冈在乔木层中平均重要值达38.6%,常与杨梅叶蚊母树、木荷、米槠、交让木混生;其蓄积量占群落总蓄积量的56.4%;②小叶青冈种群结构呈现不规则的逆J型结构,存在明显的低龄缺损的间歇型种群,但种群仍将维持相对稳定的阶段;③小叶青冈种群可通过种子和无性系进行更新,在不同生境中,其更新的方式不同。

| Abstract: | Structural features and regeneration of Cyclobalanopsis gracilis populations under various environmental conditions were studied in Tiantong Region,Zhejiang Province.The research showed that: ①The average percentage of dominancy of C.gracilis plants in adolescent stratum was about 38.6%.C.gracilis usually co-existed with waxberry,Distylium racemosum,Schima superba,Castanopsis Carlesii and Daphniphyllum macropodum.It took an average portion of 56.4% in the capacity of the whole community involved.② The populations structure was of the irregular reverse J type,distinct deficiency of young stands of C.myrsinaefolia.intermittent populations existed.However,the populations could be still maintained at a relatively stable succession stage.③C.gracilis population was renewed through seeds or clones depending,the regeneration models were different on different growth environment. |
