通过样方调查，对佛山市大浩湖潺槁木姜子（Litsea glutinosa）群落的群落特征和物种多样性进行分析和研究。结果表明，在1200 m2样地中，共有维管束植物61种，隶属于33科52属；整个群落的物种丰富度指数Margalef指数为7.5854，Shannon-Wiener指数为4.2525，Simpson指数为0.9018，均匀度指数为1.0386，该群落的层次格局为灌木层>草本层>藤本层>乔木层，成层现象较为明显。通过计算乔木层、灌木层和草本层主要物种的重要值以及频度分析得出，该群落是以潺槁木姜子为主的单优种群落，群落种类组成多样性和水平分布不均匀，其外貌终年常绿。通过对优势种种群的年龄结构分析，显示该种群处于增长状态。根据区系分析，群落内植物的区系中热带、亚热带成分比重较大，反映出植物区系具有较强的南亚热带性质。

The characteristics and species diversity of the Litsea glutinosa community at Dahao Lake of Foshan City, Guangdong province were studied by quadrat survey. The results showed that there are 61 species of vascular plants belonging to 33 families and 52 genera in 12 sample plots totaling 1200m2. The species diversity of the community is relatively low with Margalef index of 7.5854,Shannon-Wiener index of 4.2525,Simpson index of 0.9018, and the evenness index of 1.0386. The diversity pattern from maximum to minimum is ordered by shrub,herb,liana and arbor. L. glutinosa is the dominant species of the community and its composition diversity and horizontal distribution is uneven. The analysis on species important value and frequency showed that the physiognomy of the community was evergreen. The age structure of dominant population showed that the main population of the community belongs to increasing population.
