摘　　要：为了解四川凉山山系种子植物多样性及其地理区系组成特征,结合凉山地区的地形、交通条件等因素布设相应的调查样线,对凉山地区的植物多样性及其植物资源进行全面调查。结果表明:凉山山系种子植物共有163科1 072属4 561种,其中裸子植物有7科18属56种,被子植物有156科1 054属4 505种;生活型以草本植物占绝对优势;在地理成分和科级水平上,可以划分为12个分布区类型,在属级水平上,可以划分为15个分布区类型,热带成分科和温带成分属是凉山山系种子植物组成的主要部分,分别占总数的47.24%和50.65%。总之,凉山山系地理区系复杂,以热温分布为主,并呈现出从热带向温带过渡的趋势。To understand the diversity and composition characteristics of geographical flora of spermatophyte in Liangshan mountains of Sichuan,a comprehensive survey was conducted to investigate the plant diversity and plant resources in Liangshan area,with the setting up of corresponding survey lines based on terrain and traffic conditions of the area.The results showed that there were 163 families,1 072 genera and 4 561 species of spermatophyte in Liangshan mountains,including 7 families,18 genera and 56 species of gymnosperms,and 156families,1 054 genera and 4 505 species of angiosperms.Herbaceous plants were the dominant living forms.In the aspects of geographical composition and family level,there were 12 areal types,and at the genus level there were 15 areal types.The tropical families and temperate genera were the main components of spermatophyte in Liangshan mountains,accounting for 47.24% and 50.65% of the total respectively.Overall,the geographical flora of Liangshan mountains is complex.The distribution of spermatophyte species is Mainly in tropical zone and temperate zone,showing a transition trend from tropical zone to temperate zone.
