| Abstract: | Eoological dominaces of fifty-nine alpine tundra plant associations are measured.The valuesof alpine tundra phyto-communities on the Changbai Mountains generally vary from 0.05 to0.4,which is negatively correlated with species diversity.It is suitable to choose ecologicaldominance as a comprhensive index at community level. |
