Ecological studies on the relationship between the process of desertization and vegetation dynamics in the west of northeast china:community diversity and desertization process
Abstract:Plant community diversity is strongly related to DCA ordination coordinate,so it can be utilized to analyze community species diversity.In Kerqin Sandy Land and Hulunbeier Sandy Land,ecological dominance λ and Renyi‘s evenness E 1 were affected by underground water level Hill‘s diversity index of plant community,Hill‘s evenness E h and Hill‘s evenness E′ 1 ,redefined by the author,were affected by elevation and moisture coefficient,Thornthwaite index,precipitation,underground water level...
