海南俄贤岭石灰岩山地海南凤仙花所在群落植物区系及生态特征
通过样方调查对海南俄贤岭石灰岩山地海南凤仙花Impatiens hainanensis所在群落的植物区系及生态特征进行了分析.结果表明,在总面积为800m。的样地中,共记录了维管植物46科76属83种(含种下单位),以兰科(16种)、水龙骨科(5种)和大戟科(4种)等为优势.属的区系成分以泛热带分布(18属)和热带亚洲(印度-马来西亚)分布(15属)为主.群落以灌木层(29种)和草本层(45种)为主,灌木层以海南大戟Euphorbia hainanensis为优势,草本层以玫瑰毛兰Eriarosea占优势;藤本层植物9种,以眼树莲Dischidiachinensis为优势.生活型以矮高位芽(5...

| Summary: | 通过样方调查对海南俄贤岭石灰岩山地海南凤仙花Impatiens hainanensis所在群落的植物区系及生态特征进行了分析.结果表明,在总面积为800m。的样地中,共记录了维管植物46科76属83种(含种下单位),以兰科(16种)、水龙骨科(5种)和大戟科(4种)等为优势.属的区系成分以泛热带分布(18属)和热带亚洲(印度-马来西亚)分布(15属)为主.群落以灌木层(29种)和草本层(45种)为主,灌木层以海南大戟Euphorbia hainanensis为优势,草本层以玫瑰毛兰Eriarosea占优势;藤本层植物9种,以眼树莲Dischidiachinensis为优势.生活型以矮高位芽(57种)为主.频度等级分布规律为A〉B〉D〉C〉E,属于A级的种类最多,有41种,其中草本层20种.与相同生境的海南大戟灌丛群落进行了比较,并对其有效保护提出了初步建议. |
