[Addition effects of co-expansion of two bamboos on plant diversity in broad-leaved forests]

The effects of Phyllostachys edulis and Oligostachyum oedogonatum expansion on species diversity of broad-leaved forests were investigated in Wuyishan National Nature Reserve, Jiangxi Province, China. Ph. edulis and/or O. oedogonatum expansion changed community structure and species composition. The co expansion of the two bamboos in high intensity (Ph. edulis was 30-50 ind·100 m研究了不同扩张强度下毛竹和肿节少穗竹对江西武夷山常绿阔叶林群落结构和物种多样性的影响.结果表明： 毛竹、肿节少穗竹扩 张都会不同程度地改变阔叶林群落结构与物种组成，两者同时高强度扩张时(毛竹30～50 ind·100 m
