摘  要：
以贵州省中部和东南部两地典型的响叶杨次生林样地为材料,对木本植物的多样性、生态位作了分析,结果表明:响叶杨次生林不同群落乔木层树种丰富度和多样性指数高度正相关,不同群落乔木层、灌木层的丰富度、多样性指数、均匀度指数差异分别达到显著或极显著;树种多样性受海拔、坡向、土壤性质影响,多样性与海拔呈负相关,南坡、硅铝质黄壤的多样性指数最大;响叶杨的生态位宽度最大,与林内其它树种的生态位重叠度相对较小,能与其它迹地先锋树种形成稳定的次生混交林群落。

摘  要：
Analysis on tree species diversity and niche of two typical secondary Populus adenopoda forest stands in the middle and southeast of Guizhou province resulted that richness and diversity index of arbor layers had positive correlation, but richness, diversity index and uniformity of arbor and shrub layers among different communities had significant difference. The diversity was influenced by elevation, slope aspect and character of soil, and had negative correlation with elevation. The diversity on the south slope and on the Si-Al yellow soil were the biggest. The niche of P. adenopoda was the biggest, forming steady secondary mixed forest community with other pioneer plants .
