摘要
于１９９５年１２月调查了鼎湖山格木群落，在１６００ｍ２样地中，有维管植物９１种，分属４９科，７８属，以热带属占绝对优势；群落组成种类丰富，结构复杂，成层现象明显，外貌终年常绿，植物生活型以高位芽为主，乔木叶子多为单叶并以中型叶为主。这些都反映了本区高温湿润的气候特点。群落中格木种群的重要值大于其它种群，说明格木是该群落的优势种，从而命名该群落为格木群落。虽然南亚热带地区分布着丰富的豆科植物，但以豆科树种为优势种的植物群落却不多见，因此深入研究格木群落具有重要的学术意义。
Species composition and structure of the Erythrophleum fordii community wereinvestigated in December 1995 in Dinghushan Biosphere Reserve. The results showed that91 species in 78 genera and 49 families of vascular plants were found in a plot of 1 600 m2,and most plants were of tropical genera. The physiognomy of the community was evergreenall the year round. The life form in the community was dominated by phanerophytes, and theleaf form being dominated by plants with simple leaf and mesophylls for most trees. Thestratification was obvious, and the trees could be divided into three layers. Species diversityand complicated structure in the community reflected the climatic conditions of warmertemperature and higher humidity in southern subtropics. The importance value ofErythrophleum fordii population was higher than that of other population in the studiedcommunity, which was named as Erythrophleum fordii community. Although legumes areabundant in low subtropical forests, however, the communities with legumes dominated arehardly to be found elsewhere.
