Effects of phenophase differentiation on production of grassland community

Abstract: Phenophase differentiation is common in grassland community and plays an important role in maintaining biodiversity. However, little attention was paid on the effects of phenophase differentiation on grassland production. The results from a 2year experiment conducted in Inner Mongolia showed that there was an obvious phenophase differentiation in Inner Mongolia grassland community. As the restoration time extending, the degree of phenophase differentiation increased, and the primary production of natural grassland community was promoted; also, a positive significant correlation between phenophase differentiation degree and species richness and species evenness was observed.
