摘要:
在野外调查和分类处理的基础上,对商南金丝峡蕨类植物区系进行了研究.商南金丝峡蕨类植物由19科39属86种(含变种)组成,主要的科是鳞毛蕨科、蹄盖蕨科、水龙骨科、铁角蕨科和卷柏科等,它们包含的种数占总种数的65.12% ;主要的属为卷柏属、铁角蕨属、耳蕨属、鳞毛蕨属和蹄盖蕨属。区系地理成分复杂,属的分布类型以热带亚热带性质为主,有15属,占总属数的51.72%;种的地理成分以东亚分布和中国特有分布最为突出,有67种,占总种数79.76%,表现出热带向暖温带过渡的特点。
Abstract:
The fern flora in Jinsi Gorge of Shangnan county was investigated through field study. It was found that ferns in this area consist of 86 species (including varieties) which falls into 39 genera of 19 families. Most of them belong to dryopteridaceae, athyriaceae, polypodiaceae, aspleniaceae or selaginellaceae, accounting for 65.12% of the total number of species.The dominant genera are selaginella, polystichum, asplenium, dryopteris and athyrium.Those flora are geographically complicated,with 15 genera to be tropical or subtropical ones, accounting for 51.72% of the total genera.Most species are endemic plants in eastern Asia and China, which are distributed crossing from tropical to warm temperate zones. 67 species are the types, taking up 79.76% of the total number of species.
