摘　　要：以严重退化第四纪红粘土为研究对象,选择7种模式重建森林恢复27a后的群落多样性及稳定性进行研究,结果表明不同重建模式27a后群落Marglef丰富度指数R为封育马尾松林分>谷坊马尾松林分>竹节沟湿地松林分>种草竹节沟马尾松林分>无谷坊马尾松林分>竹节沟马尾松林分>强烈干扰马尾松林分,而Shannon-Wiener多样性指数H、Simpson优势度指数P和Pielou均匀度指数J均表现为封育马尾松林分、种草竹节沟马尾松林分、竹节沟湿地松林分较大,而竹节沟马尾松林分、谷坊马尾松林分、无谷坊马尾松林分较小。群落稳定性大小顺序为竹节沟马尾松林分>无谷坊马尾松林分>谷坊马尾松林分>封育马尾松林分>种草竹节沟马尾松林分>竹节沟湿地松林分。The paper took degraded quaternary red soil in Jiangxi province as the object of the study.Species diversity and community stability of 7 kinds of rehabilitated forests 27 years later were studied.The results showed that the Marglef richness index（R） were in the order of Pinus massoniana forest without disturbancePinus massoniana forest with check damPinus elliotti forest with bamboo-burl-groovePinus massoniana forest with planting grass and bamboo-burl-groovePinus massoniana forest without check damPinus massoniana forest with bamboo-burl-groovePinus massoniana forest with intense disturbance.Pinus massoniana forest without disturbance,Pinus massoniana forest with planting grass and bamboo-burl-groove,Pinus elliotti forest with bamboo-burl-groove were higher than Pinus massoniana forest with bamboo-burl-groove,Pinus massoniana forest with check dam,Pinus massoniana forest without check dam in Shannon-Wiener index（H）,Simpson index（P） and Pielou evenness index（J）.The community stability was in the order of Pinus massoniana forest with bamboo-burl-groovePinus massoniana forest without check damPinus massoniana forest with check damPinus massoniana forest without disturbancePinus massoniana forest with planting grass and bamboo-burl-groovePinus elliotti forest with bamboo-burl-groove.
