<正>采用植物群落学的研究方法,对江西官山自然保护区长柄双花木灌丛群落特征及多样性进行了研究。结果表明,群落结构特征为单优势种群落,乔木层种类少,树冠不连续,灌木层以长柄双花木占绝对优势,林下更新较差。群落的物种多样性指数低,表明生境条件特殊,群落结构不稳定。

Using phytocoenological methods,the Disanthus cercidifolius var.longipes shrubland in the Guanshan nature reserve of Jiangxi province had been studied.The results showed the community was a that of consociation.A few species in the arborous layer and crown were disconnected.The shrub layer was dominated by Disanthus cercidifolius var.longipes but seedling was few.Species diversity of the shrubland was lower,because the habitat was barren and the community was unstable.
