Community Characteristics of Rhododendron simiarum in Nanling National Nature Reserve, Guangdong
摘要
Abstract
Based on a field investigation, the floristic composition, structure, physiognomy and species diversity of a Rhododendron simiarum community in Nanling National Nature Reserve of Guangdong Province were analyzed. Results showed that there were 121 vascular species, belonging to 79 genera and 52 families. Pantropic elements were the dominant, followed by tropical and temperate elements which showed obvious transitional characteristics. The community was obviously dominated by Rhododendron, simiarum. The vertical structure of the community was composed of arbor,shrub and herb layers, and interlayer species were poor. According to the Raunkiaer Frequency Law,species in 1% -20% occurrence frequency dominated the community, accounting for 60% of the total species. Young trees of the Rhododendron simiarum population were less, indicating that the population was in the state of being degraded. The diversity indices, such as Simpson dominance index, Shannon-Wiener index and Pielou evenness index, showed similar trend, with arbor layer > liana layer > herb layer > shrub layer in the community.关键词
