Diversity and Flora Analysis of Spermatophyte in Liangshan Mountains,Sichuan Province
摘要
Abstract
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 sper-matophyte in Liangshan mountains,including 7 families,18 genera and 56 species of gymnosperms,and 156 families,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.关键词
