摘要
广东象头山国家级自然保护区处于我国南亚热带常绿阔叶林地带,有一定面积的红花荷群落分布。调查结果表明,红花荷群落的组成种类丰富,1 600 m2样地有维管植物95种;科、属区系以热带性成分为主;生活型以高位芽为主,有56种,占总数的58.9%,其中,大、中高位芽33种,占高位芽的58.9%,常绿性高位芽53种,占高位芽的94.6%;群落层次结构可分为乔木层、灌木层、草本层和层间层,比例为36.8%,24.2%,17.9%,21.1%,乔木层比例最高,层间植物较多,这些均说明红花荷为喜温暖、湿润、对生态环境要求较高的植物。红花荷林是我国南亚热带常绿阔叶林类型中较特殊的群落,应加以保护和利用。
Guangdong Xiangtou mountin National Nature Reserve is located at the evergreen broad-leaf forest in the south subtropics of China. The invegegation and annylization showed that the composition of the Rhodoleia championii commmunities was abundant. There were 95 vascular plants in the sample land as 1 600 m^2 ;through the analysis of the sections,categories and districts, the main element was tropical ones ; the Phanerophytes, belonging to 56 species, were the dominant life-form, accounted for 58.9% of the phanerophytes, there were 33 macrophanerophytes and mesophanerophytes medium, accounted for 58.9% of the phanerophytes. There were 53 evergreen phanerophytes, which cover 94.6% of the phanerophytes. Communities layer structures could be divided into tree layers, the shrub layer, the herbaceous layer and the interlayer, the ratio were 36. 8%, 24. 2%, 17.9%, 21.1%, the proportion of the tree layer was the highest, there were lots of plants between them. All these can be explained that Rhodoleia championii is a plant which is fond of warm, humid, and higher ecological environment. Rhodoleia championii communities as a special communities in evergreen broad-leaf forest types in the south subtropics of China should be protected and exploited.
