摘　　要：长柄双花木为濒危植物,分布区狭窄,群落罕见。研究表明,江西官山自然保护区长柄双花木灌从为单优势种群落,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。物种多样性不高,林下更新较差。Disanthus cercidefolius var. Longipes is a rare and endangered plant species, whose distribution is limited so the communities are seldom seen. The study shows the Disanthus cercidifolius var. longipes shrubland in the Guanshan Nature Reserve of Jiangxi Province is a consociation. A few species in the arborous layer and crown are disconnected. Shrub layer is dominated by Disanthus cercidifolius var. longipes. Species diversity is low. Seedlings are few.
