采用标准木法、回归分析法(乔木层)和样方法相结合, 分析了黄竹(Dendrocalamus membranaceus Munro)侵入对群落生物量的积累和物种多样性的影响, 结果显示黄竹侵入严重影响生物量的积累, 群落生物量随黄竹侵入量的增多而下降。随着黄竹侵入量的增加, 群落内物种数量减少, 物种多样性指数降低。
 

Effects of invasion of Dendrocalamus membranaceus Munro on community biomass and plant
diversity were analysed by sample tree , regression analysis (for tree layer)and plot method .The results show that the invasion of D .membranaceus effect the biomass distinctively .The biomass abate with the D .membranaceus increment .The plant diversity index and species number decrease with D .membranaceus increment .
