摘要
调查统计,磐安共有蕨类植物112种,隶属于60属、34科。地理成分分析表明,种的地理成分以东亚分布,特别是中国-日本分布为主,区系显示出较明显的亚热带-暖温带过渡的特征。同时从水平分布、垂直分布和生态分布三种分布型分析了磐安蕨类植物资源的分布规律,并根据其用途,划分为药用植物资源、食用植物资源、观赏植物资源等。在以上研究的基础上,提出了合理开发利用磐安蕨类植物资源的一些建议。
Panan flora lies in the middle of Zhejiang Province. Based on the investigation andstatistical analysis, the pteridophytes resources and their development in Panan were studies. It was known that there were 112 species （including subspecies and varieties） of wild pteridophytes, which belonged to 60 genera and 34 families. The representative families were Dryopteridaceae, Polypodiaceae, Thelyptefidaceae and Athyriaceae. The main genera were Dryopteris, Selaginella, Asplenium and Arachniodes. At species level, the east Asia and endemic Chinese element took the largest proportion （accounting for 83. 3 % ）, which represented to the feature of subtropicstransition to warm temperated area-type. So the reglon should belong to the east Asia zone. The distributive regulation of pteridophytes were discussed in three distributive types： viterical distribution, horizontal distribution and ecological distribution. In vertical distribution, the pteridophytes mainly located in the evergreen broadleaved forest and the evergreen coniferous-broadlcaved mixed forest at the altitude of 600-1 000 m. In horizontal distribution, their distribution was basically uniform in the whole flora scale because of its small stride oflongitude and latitude. But the ecological factors such as soil, light and water etc. played very important affection on their distribution in smaller scale. In ecological distribution, they were clarified into five types： Terrestrial pteridophytes, Epiphytic pteridophytes, Rock pteridophytes, Climbing pteridophytes and Aquatic pteridophytes. On the basis of the wild pteridophytes, thepteridophytes resources could be classified into medicinal plant resources, edible plant resources, ornamental plant resources, chemical industrial raw material plant resources etc. According to the characteristic of Panan, some suggestions on how to rationally exploit and utilize the pteridophytic resources of Panan were put forward and some aspects should be strengthen such asbasic research work, exploitation strategies, r
