| 摘 要： | 对中国特有珍稀濒危植物乐东拟单性木兰（Parakmeria lotungensis）的分布现状、资源量、种群结构和群落特征进行了全面的野外调查。结果表明,乐东拟单性木兰零星分布在我国18°44′～29°24′N,107°50′～119°09′E之间的热带至亚热带森林中,估测个体数量不足15000株,其中成年植株数量不足2500株。生境破碎化与乐东拟单性木兰自身的生物学和生态学特性是影响种群更新的重要因素。人为破坏是造成乐东拟单性木兰种群急剧缩减的直接原因,对乐东拟单性木兰的分布现状提出了保护策略和建议。

| Abstract: | Distribution,resource,population structure and community character of rare and endangered species Parakmeria lotungensis were investigated.The results showed that P.lotungensis had a sporadic distribution among tropical and subtropical forests between 18°44′-29°24′N,107°50′-119°09′E,with a total population of less than 15000 individuals among which less than 2500 were mature individuals.Habitat fragmentation and biological and ecologi-cal characteristics of P.lotungensis were important factors for population regeneration.Human destruction was most direct factor contributing to the rapid reduction of the population.Protection strategies of P.lotungensis are discussed. |
