研究其群落组成和环境特征是物种保护和森林恢复的迫切需要。檫树是中国南方的保护植物。我们的目的是利用浙江省非商业性森林生态监测样地(NCFEMPs)系统的数据来评估S.tzumu与环境变量之间的关系。在调查的 NCFEMP 中,我们发现 96 个地块(20 × 20 m)含有 S.tzumu 种。使用双向指示物种分析 (TWINSPAN) 和典型对应分析 (CCA) 对 96 个样地的物种组成和相关环境数据进行了分析。 TWINSPAN结果表明,S.tzumu关联有八种类型。每个协会都有自己的组成和环境特征。 CCA结果表明,高程和坡向是决定S空间格局的主要变量。 tzumu 社区。我们的研究成果对于保护物种的管理和保护具有重要的理论和实践意义。
Studying the community composition and environmental characterization is an urgent need for species conservation and forest restoration.Sassafras tzumu(Hemsl.) Hemsl is a protected plant species in southern China. We aimed to assess the relationship betweenS.tzumuand environmental variables using data from the Noncommercial Forest Ecological Monitoring Plots (NCFEMPs) system in Zhejiang Province. Among the investigated NCFEMPs, we found 96 plots (20 × 20 m) containingS.tzumuspecies. The species composition and associated environmental data from 96 plots were analyzed using two-way indicator species analysis (TWINSPAN) and canonical correspondence analysis (CCA). The TWINSPAN results showed there were eight types ofS.tzumuassociations. Each association had its own composition and environmental characteristics. The CCA results showed that the elevation and slope aspect were the major variables that determined the spatial patterns ofS. tzumucommunities. Our results will be of great theoretical and practical significance for protected species management and conservation.
