Abstract
The results of plant diversity analysis in different degraded stages of Seriphidium transillense desert grassland show that media-degradation maintains high diversity,changes as follows: media-degradationheavy degradationover-degradationnon-degradation.The related analysis of the richness,evenness and diversity of the community species indicated that evenness makes greater contribution to species diversity than the species richness.The result of the β diversity analysis manifests that species replacement become slowly in neighbor degraded stages along with the increase of degradation.
