【摘要】 由于蒙古高原位于亚洲温带地区 ,广布的北温带和温带亚洲成分 ( 5种 ,占 31 .2 5% )构成了该属的基本成分 ,在蒙古高原的北部渗入欧洲 -西伯利亚成分 ( 4种 ) ,在东部渗入了东亚区系成分 ( 4种 ) ,分别占 2 5% ,反映了该属植物区系成分与西伯利亚和东亚森林区植物区系的紧密联系 .亚洲中部成分 ( 3种 ,占 1 8.75% ) ,特别是达乌里 -蒙古种 ( 2种 )为蒙古高原特有种 ,这是该属植物在蒙古高原长期适应演化的结果 .蒙古高原野豌豆属植物与东西伯利亚、东北和华北地区联系较为紧密更多还原

【Abstract】 Because the Mongolian Plateau lies in the Temperate Zone of Asia, its basic floristic elememt of the genus is composed of widespread North Temperate Zone and Temperate Asian Zone element (5 sp.,31.25%), the Europe Siberia element (4 sp.,25%) intermingles in North of the Mongolian Plateau, and East Asian element (4 sp.25%) in the East, These show the close relationship between the flora of the genus and the flora of Siberia’s and East Asian.forest zone.. Three species belong to the Central Asian element (18.75%), the Dauria Mongolia species (2sp.) are the unique species especially,it is the adaptable evolutionary result that the genus live in the Mongolian Plateau long term.The flora of the Mongolian Plateau is influenced greatly by that of the East Siberia, East North China and North China.更多还原
