| 摘 要： | 在野外调查基础上,分析了湖北省长阳地区光叶珙桐群落外貌与结构特征。结果表明:在2900m2的样方中,有维管植物238种,隶属于81科170属;群落植物区系丰富、古老、特有性强;群落中有金钱槭、水青树、白辛树、领春木、连香树、天师栗和大叶三七等珍稀濒危植物;其生活型以包括藤本在内的高位芽植物占绝对优势,达47.06%;叶级以中型叶为主,占68.07%,小型叶次之,占28.57%;叶型以单叶占有较大的优势,达78.99%叶质以纸质叶为主,占67.12%。群落垂直结构较复杂,成层现象明显,可分为乔木层、灌木层、草本层和层间植物;年龄结构和高度结构分析表明,光叶珙桐种群更新不良,具有衰退的趋势。
