中文摘要：

采用相邻格子法,对闽北建瓯福建青冈天然林进行群落调查,分析了福建青冈群落的种类组成、群落物种多样性。结果表明：建瓯福建青冈群落有明显的乔木层,郁闭度较大,林下植被较少;综合分析多样性各个指数,可知建瓯福建青冈群落的单一性较强,多数种群的扩展受到限制,虽然该群落目前是以福建青冈为优势树种的进展演替阶段,但如果一旦生境改变,该群落将可能发生逆行演替。

英文摘要：

The community of natural forest of Cyclobalanopsis chungii were investigated on Jian＇ou in northern Fujian by using contiguous grid quadrat method.Species composition species diversity of C.chungii community were analyzed.Result shows that： C.chungii community in Jian＇ou in Fujian have significant tree layer,greater canopy density less understory vegetation;through comprehensively analysis of the various diversity index,it shows that C.chungii community in Jian＇ou in Fujian have stronger singleness;the expansion of most of the species was restricted.The community is now in successional stages of progress of taking C.chungii as the dominant tree species;the community will be turned to retrogressive succession if once the habitat changes.
