| 摘 要： | 应用TWINSPAN分类和DCA排序方法分析山西历山山核桃群落生态关系。结果表明:1)应用TWINSPAN将山核桃群落的35个样方划分为7个群丛,分别是山核桃-连翘-升麻群丛、山核桃-连翘+牛奶子-蓝萼香茶菜群丛、山核桃-连翘-草乌头群丛、山核桃-连翘-香薷群丛、山核桃-连翘-披针叶苔草+筋骨草群丛、山核桃-连翘-风毛菊+牛尾蒿群丛和山核桃-连翘-藜芦群丛;2)35个样方DCA排序图较好地揭示了山核桃群落的分布格局与环境梯度的关系,排序图第1轴基本反映各群丛所在生境的坡向变化,第2轴基本反映了植物群落的地形和土壤类型变化,坡向、地形和土壤类型决定了山核桃群落类型的规律性变化;3)7个群丛草本层优势种在DCA排序轴上的分布格局在很大程度上影响着群丛在DCA排序轴上的分布格局。

| Abstract: | The ecological relationship between Juglans mandshurica communities and environment was analyzed by using TWINSPAN and DCA. The results were as the following: J. mandshurica communities were classified into 7 associations by TWINSPAN,which were Assoc. Juglans mandshurica-Forsythia suspensa-Cimicifuga foetida,Assoc. Juglans mandshurica-Forsythia suspensa+Elaeagnus umbellata-Rabdosia japonica var. glaucocalyx,Assoc. Juglans mandshurica-Forsythia suspensa-Aconitum kusnezoffii,Assoc. Juglans mandshurica-Forsyth... |
