| 摘 要： | 选取太湖流域2种具有代表性的针阔混交林，应用传统林分结构因子配合混交度、角尺度、大小比数和开敞度4个参数进行比较，分析冬青湿地松混交林和栎树湿地松混交林的林分基本特征、空间结构和演替趋势。结果表明，冬青湿地松林的物种丰富度相对较高；对空间结构各参数进行比较，冬青湿地松林空间结构优于栎树湿地松林，林分处于相对稳定状态。其中在冬青湿地松林中，山矾、冬青可能会发展成为优势树种；在栎树混交林中，麻栎和栓皮栎的生长空间受限制，演替过程中优势度会有所下降，短柄枹和构树可能成为优势种。

| Abstract: | In order to understand the features and situation of complex spatial structure along Taihu Lake that provides the basis for scientific management for forests.Two representative mixed forests in Taihu Basin Suzhou,Jian-gsu Province were analyzed with traditional stand structure indices and four spatial structure indices of mingling,an-gle index,neighborhood comparison and opening degree.The results showed that the species richness of Ilex purpurea and Pinus elliottii mixed forest was relatively higher.Comparison of the parameters from the spatial structure,I.pur-purea and P.elliottii mixed forest was better than Quercus and P.elliottii mixed forest.In I.purpurea and P.elliottii mixed forest,I.purpurea,Symplocos spectabilis may become dominant tree species.In Quercus and P.elliottii mixed forest,because of Q.acutissima and Q.variabilis growing space were constrained,their succession dominance could be decline,Q.glandulifera and Broussonetia kazinoki would become the new dominant species. |
