摘要
生态优势度(ecological dominance)或称集中优势度(dominance concentration),是综合群落中各个种群的重要性,反映各种群优势状况的指标,是群落结构的一个度量值。
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.
