摘　　要：针对洱海周边面山选取了典型样地31个,采集到洱海周边面山植物475种,隶属于335属、121科。调查及标本鉴定结果表明:洱海面山带有维管束植物(除栽培)100科、294属、403种。其中蕨类植物8科15属21种;裸子植物1科1属1种;被子植物91科278属381种:其中单子叶植物16科63属82种;双子叶植物75科215属299种。对调查区的维管束植物科属区系组成进行分析,指出了植物科属泛热带和热带区系成分明显,这将为后期对洱海面山植被恢复选取树种提供参考,也为进一步加强洱海的保护及其合理开发利用提供理论依据。In this study,31 typical sample plots were selected for the surrounding mountains of Erhai Lake,and 475 species of plants belonging to 335 genera and 121 families were collected.Besides,the investigation and specimen identification showed that there are 100 families,294 genera,403 plants(except cultivation)and 403 species.There are 21 species of ferns in 8 families and 15 genera;there are 1 species of gymnosperms,1 family and 1 genera;There are 381 species of angiosperms,91 families and 278 genera;there are 82 species of monocotyledonous plants,16 families and 63 genera.There are 299 species of dicotyledonous,75 families and 215 genera.The analysis of the flora composition of vascular plant families in the survey area shows that the plant families have no tropical and tropical flora composition is obvious,which will provide a basis and reference for the selection of vegetation restoration in the later period,and also provide a theoretical basis for further strengthening the protection of Erhai Lake and its rational development and utilization.
