摘要: 通过样方调查,对广东银瓶山森林公园游览区内红花荷(Rhodoleia championii)群落的群落特征和物种多样性进行分析。结果表明:在1 600m2的样地内共有维管束植物73科116属153种,属分布类型以热带、亚热带性分布类型为主;群落以红花荷为建群种,优势地位明显;群落分为乔木层、灌木层和草本层3层,层间藤本丰富,生活型以小高位芽植物为主,叶以单叶、纸质、中小型叶为主;按Raunkiaer标准,群落内的种群频度为1%~20%的种类占优势,为总种数的67.97%。由于人为干扰因素,红花荷的种群呈衰退状态;群落各层的多样性指数表现出不相一致的趋势,以灌木层的多样性指数最高。

Abstract: On the basis of field investigation of a 1 600m2 plot,We analyzed physiognomy,structure,the floristic composition and species diversity of a Rhodoleia championii community in Donguan Yinpingshan Forest Park,Guangdong. There were 153 vascular species,belonging to 116 genera and 73 families. Trop. & Subtrop. elements were the dominant. The community was mainly dominated by Rhodoleia championii. The vertical structure of the community was composed of Tree layer,shrub layer,herb layer and rich interstater plants,and dominated by evergreen plants in Microphanerophytes. According to the Raunkiaer Frequency Law,species in 1-20% occurrence frequency dominated the community,accounting for 67.97% of the total species. Because of the human interference,the number of the Saplings and young Rhodoleia championii trees was less,which indicates the population was on the declining trend. The different diversity indices showed different trend among layers in the community except that the shrub layer had the highest diversity.

Key words: Dongguan, Rhodoleia championii, community, species diversity, community characteristics
