| Abstract: |
| Tree species-abundance in forests is a function of geographical area and climate, although it is not clear whether such relationships apply to mass islands. We examined the spatial pattern of tree species in mass islands along the coast of Zhejiang, East China Sea using the Preston model, to identify the relationships between tree communities and climatic conditions. The results show that: (1) the biogeographical distribution of tree species-abundance conformes to Preston’s log-normal pattern, and is in accordance with the findings in both tropical rainforests and estuarine forests; (2) the climatic factors related to tree communities in mass islands are similar to that of the subtropical zone, including the major species of evergreen needle-leaf, broad-leaf and deciduous broad-leaf forests. We conclude that the Preston model can be applied to the trees of mass islands and thus facilitate the systematic ecological researches of vegetation species’ composition in subtropical zone. |

| 采用数理统计方法对浙江海岛植被乔木层种-多度的格局进行研究，并将参数估计法和遗传算法应用于Preston对数正态模型在浙江海岛植被乔木层种-多度格局拟合中，并分析浙江海岛植被（乔木）及其与气候因子的相关关系。结果表明：（1）浙江海岛植被乔木层种-多度格局符合对数正态分布特征，对数正态分布模型在浙江海岛植被乔木层种-多度分布中的适用性与在热带雨林等非海岛群落种-多度格局的适用性一致；（2）浙江海岛植被与毗邻区域的植被同处于相似相近的气候因子下，具有亚热带气候的主要特征，包含了从温带至亚热带地区的针阔混交林、常绿阔叶和落叶阔叶的众多属、种，可作为亚热带气候下植被重要组成部分开展系统生态学研究。 |
