摘　　要：对广东省惠州市惠城区古寨保护区内苏铁蕨（Brainea insignis）分布的森林群落进行群落特征分析，结果表明：群落郁闭度为0．6～0．8，群落高度在10 m左右，包含乔木、灌木、草本3层；对苏铁蕨种群生活力分析表明，马尾松针阔叶混交林是苏铁蕨最适宜生存的群落类型；相关分析表明，群落乔木郁闭度与苏铁蕨生活力具有一定的相关性，但不显著，是影响苏铁蕨能否在林内生存的主要因子。Brainea insignis is a national key protected ferns.We studied the community characteristics of forest community which include the B.insignis in Guzhai Nature Reserve,Huicheng District,Huizhou,Guang-dong.The results indicated that the canopy closure of these communities was 0.6-0.8,the mean height of these communities was about 1 0 m.These communities included trees,shrubs and herbaceous.The plant life force of B. insignis indicated that Pinus massonniana coniferous-broadleaved mixed forest was suitable for B.insignis.Correla-tion analysis showed that the most relevant viability of B.insignis plant life force was the canopy density,but not significant.Tree size was the major variable which could influence the survival of B.insignis.
