| 摘 要： | 横断山区共有种子植物本地特有属13个（隶属于9科21种）、新特有属7个、古特有属6个。其中5个古特有属为北极—第三纪成分或北方成分,1个古特有属为古地中海残遗,并且都分布在横断山区中部1 750m-3 500m的海拔带上,表明横断山区海拔1 750m-3 500m是古特有属在第三纪以后,由于气候变化、第四纪冰期作用、古地中海退却及横断山区形成等复杂过程中的一个避难所和分化区域。

| Abstract: | In the study,total 13 genera endemic to Hengduan Mountains are analysed,the results show that there are 7 new endemic and 6 paleo-endemic genera.5 paleo-endemic are the Artic-Tertiary elements or boreal,the other one is Tethys element,all of them distributed in the range from 1750m to 3500m.So we suggest that the elevation range from 1 750m-3 500m in the Hengduan Mountain is either an important refuge during the quaternary glacial period or differentiate center. |
