摘　　要：通过对浙江千岛湖桂花岛的实地调查,采用相对密度、相对频度、相对盖度及重要值对各群落植物进行种群数量特征比较,对该桂花群落的数量特征进行了统计分析。结果表明桂花岛典型的群落类型为青冈栎-桂花群落以及香果树-桂花群落。桂花对土壤没有特别的要求,尤其在贫瘠的条件下具有较强的适应能力,成丛分布,从而成为群落的优势种。On the bases of investigation in osmanthus Island, Qiandao Lake, Chun＇an County, Zhejiang Province, relative density, relative frequency, relative cover and important value were studied on the community of Osmanthus fragrans. The results showed that the Cyclobalanopsis glauca - Osmanthus fragrans - community and Emmenopterys henryi - Osmanthus fragrans - community were typical community type in this osmanthus island. Osmanthus fragrans was in caespitose distribution and easily to be a dominant species due to its stronger adaptability in the poor sites.
