Structure characteristics and species diversity of Zanthoxylum micranthum in Zhejiang Province
-
摘要: 在浙江省临安市高山村野外调查的基础上,对浙江省小花花椒Zanthoxylum micranthum群落进行分析研究,得出该群落结构的特点:物种丰富,共有维管束植物70科127属166种;地理成分较为复杂,区系过渡性特征明显;根据Raunkiaer的生活型统计,高位芽植物数量最多,占62.7%,其他生活型植物相对较少;群落垂直结构有乔木层、灌木层和草本层,以及层间植物;该群落中Shannon-Wiener指数、Pielou均匀度指数和Simpson指数各层的排列顺序表现一致:乔木层>灌木层>草本层。图1表4参14Abstract: Based on the quadrat investigation,community structure and species diversity of Zanthoxylum micranthum in Zhejiang Province were analyzed. The results showed that there was rich species diversity in this community; vascular species belonging to 70 families,121 genera,166 species were found. The characteristics of floristic interims were obvious. According to Raunkiaers classification,phanerophytes accounted for the greatest number which was 63.69 per cent,the number of other plants was comparatively small. The vertical community structure could be divided into tree layer,shrub layer,herb layer as well as inter stratum plants. Within the community,Shannon-Wieners indices,Pielous indices and Simpsons indices were biggest in the tree layer. While those of shrub layer and herb layer ranked the second and the third respectively.[Ch,1 fig. 4 tab. 14 ref.]
