Studies on the community characteristics of Rhododendron simiarum in Jinggang Mountain
摘要
Abstract
Based on data collected from five plots of Rhododendron simiarum in the Jinggang Mountain, the species and floral composition, the community structure and the species diversity were analyzed. Results showed that there were 50 vascular plant species belonging to 43 genera and 30 families, among them, 6 plant species belonging to 6 genera and 5 families were pteridophyte, 4 plant species belonging to 4 genera and 4 families were gymnosperm, and 40 plant species belonging to 33 genera and 21 families were angiosperm. The floristic analysis showed the flora is ancient and geographical elements are complex, tropical elements are obvious with a certain proporiton of temperate-zone elements. The structures of Rhododendron simiarum community are many storied all-aged forest,. The constructive species are Rhododendron simiarum, Fokienia hodginsii, Castanopsis eyrei, Pinus taiwanensis, Elaeocarpus japonicus and Pseudotaxus chienii. The species diversity index in Rhododendron simiarum was low with high variations among plots except Pielou index, and the variation patterns of species diversity are similar whichever the index is used. Generally, the order of the magnitude of species diversity was: shrub layer > tree layer > herb layer.关键词
