摘 要:浙江龙王山自然保护区共有观赏蕨类植物145种,隶属于33科68属。总结该区观赏蕨类植物的区系组成及特征,将属的分布区类型分为10个,其中以世界分布为主,共18属,占总属数的26.5%;其次为泛热带分布和东亚分布,占总属数的比例分别为20.5%、14.7%。将观赏蕨类分为陆生、附生、水生、藤本4种生态类型,陆生蕨类最多,共104种,占该区蕨类总种数的71.7%。提出龙王山观赏蕨类植物应用方式包括园林绿化、盆栽观赏、盆景配置、切花配叶等,并探讨该区野生观赏蕨类植物的保护与开发利用。A total of 145 fern species (including subspecies and varieties) which belong to 68 generas and 33 families are reported from Longwangshan Nature Reserve, Zhejiang Province. An analysis of geographical and floristic elements of ornamental pteriodophytes in this area indicates that 18 genera (26.5% of total) belong to cosmopolitans, 15 (25.0%) to the pantropical elements and 10 ( 14.7% ) to the East Asia elements, cosmopolitans are the most important ones. According to their habits, ferns in this nature reserve can be classified into 4 types, I. e terricolous - type (71.7 % of total), epiphyte - type (24.8 % ), aquatic - type (2.1%) and liana -type (1.4%). An investigation result indicates that they can be applied to garden, pot cuture, potted landscape and cut - flower. Conservation, exploitation and utilization values of wild ornamental pteriodophytes in Longwangshan are also discussed in this paper.
