摘　　要：采用典型样地调查、生物多样性指数计算等方法对椿叶花椒天然群落物种多样性进行调查研究,结果表明:椿叶花椒群落乔木树种构成复杂,但椿叶花椒重要值高达23.0836,远高于其他乔木种。植物生长型与群落物种多样性的关系为:乔木层的物种丰富度明显高于灌木层和草本层,物种多样性指数表现出乔木层>草本层>灌木层的规律,均匀度变化规律为草本层>灌木层>乔木层。调查区域内不同海拔中各层次物种多样性指数变化趋势各不相同。Typical plot survey methods and biodiversity index calculation were used to analyze the biodiversity of Zanthoxylum ailanthoides Sieb.et Zucc..The results showed that the tree species composition of Zanthoxylum ailanthoides Sieb.et Zucc.communities was complex,but the important value of Zanthoxylum ailanthoides Sieb.et Zucc.was as high as 23.0836,which was far higher than other arbor species.The species richness for different strata were in the following order:the tree stratum was significantly higher than that shrub stratum and herb stratum,the species diversity indexes were in the following order:tree stratum>herb stratum>shrub stratum,and the evenness were in the following order:herb stratum>shrub stratum>tree stratum.The species diversity indexes in different altitudes had different variable.
