| 摘 要： | 本文对哀牢山国家级自然保护区蕨类植物的资源进行研究。哀牢山位于云南省中南部,横断山南部和青藏高原东南缘,是国家级自然保护区,面积为677 km2,范围为北纬23°36′—24°56′、东经100°44′—101°30′之间,分别跨越镇沅县、景东县、南华县、楚雄市、双柏县和新平县六个县(市)。本文首次报道了哀牢山蕨类区系有蕨类植物48科,118属,446种(包括变种和变型)。该蕨类区系最大的科是鳞毛蕨科Dryopteridaceae、水龙骨科Polypod iaceae和蹄盖蕨科Athyriaceae,最大的属是耳蕨属Polystichum、蹄盖蕨属Athyrium、鳞毛蕨属Dryopteris和卷柏属Selaginella。根据区系分析的结果,该蕨类区系是亚热带性质的区系,热带亚洲成分随着海拔的升高,比例逐渐降低,而中国-喜马拉雅成分随着海拔的升高逐渐升高,该蕨类区系具有较丰富的中国特有成分。哀牢山国家级自然保护区可供经济利用的蕨类超过300余种,按照其用途可划分为珍稀濒危蕨类植物、药用蕨类植物、食用蕨类植物、观赏蕨类植物、指示蕨类植物、工业原料蕨类植物、编织蕨类植物、饲料和绿肥蕨类植物、农药类蕨类植物资源等9种资源类型。其中,有国家二级保护植物4种;药用蕨类植物有45科76属178种,占中国药用蕨类植物科属种的比例分别为91.8%、65.5%和41.1%。最后,本文讨论了资源开发利用现状及前景,哀牢山蕨类植物资源丰富,种类多,数量大,开发潜力大,但长期以来一直未能受到重视。

| Abstract: | This paper deals with the fern medicine resources of Ailaoshan Mountain national nature reserve.Based on the more than two years' field investigation(specimens were deposited in PYU) and consulting the specimens of PYU and KUN,the floristic phytogeography of pteridophytes of 446 speices (including all varieties and forms) and 118 genera in 48 families were reported at first from this region up to now.The geographic components of species are mainly Tropical Asia,East Asia and Endemic to China.The actuality and foreground of exploitation and utilization in these pteridophytes also were discussed in this paper,the pteridophytic resources of Ailaoshan Mountain national nature reserve are abundant,species and quantities are enriched,also have comprehensive exploitation and utilization foreground,but the exploitation and utilization of pteridophytic resources were ignored in actuality.The pteridophytic resources from Ailaoshan Mountain national nature reserve more than 300 species which can be utilization.Among of which,there are 45 families,76 genera and 178 species of medicinal pteridophytes,they separately occupy 91.81% of total families,65.5% of total genera and 41.1% of total species. |
