In this paper,based on the locus characteristics of aboveground standing crops and density dynamics of main populations in degenerated grassland community during the restoring succession from 1983 to 1993,we can devide these populations into 6 types.dominant increase type:Leymus chirensis;slow increase type:Stipa grandis; typical decline type:Cleistogenes squarrosa and Artemisia commutata; logging decline type:Artemisia frigida; intemediate transition type:Agropyron michnoi, Allium bidentatum, and Koeleria ...
