Six species，Leymus chinensis，Stipa baicalensis，Carex duriuscula，Artemisia frigida，Potentilla acaulis and Potentilla bifurca in Hulunbuir meadow steppe were used to study the effects of grazing intensity on carbon，nitrogen，phosphorus nutrients，stoichiometry and storage of dominant and degraded plants.The results showed that:(1)With the increase of grazing intensity，the carbon content of the dominant species of L. chinensis decreased significantly，and the carbon content of the degradation indicator species A. frigida increased significantly.Moderate-severe grazing significantly increased the total nitrogen content of six plants，as well as the total phosphorus content of dominant species of L. chinensis and establishment species of S. baicalensis(P<0.05).(2)With the increase of grazing intensity，the carbon-nitrogen ratio and carbon-phosphorus ratio of the dominant species of L. chinensis and the establishment species of S. baicalensis decreased significantly，and the non-grazing and light grazing were significantly higher than those of the heavy grazing (P<0.05)；Grazing reduced the carbon-nitrogen ratio and carbon-phosphorus ratio of the species C. duriuscula，A. frigida，P. acaulis and P. bifurca，and the nitrogen-phosphorus ratio of C. duriuscula.(3)Grazing reduced the carbon，nitrogen and phosphorus storages of the dominant species of L. chinensis(P<0.05).Compared with no grazing，the carbon，nitrogen and phosphorus storages of moderate-heavy grazing decreased by 87.10%～98.41%，82.01%～97.55% and 82.33%～97.41%，respectively；The carbon，nitrogen and phosphorus storages of degradation indicator species R. frigida and P. acaulis showed a significant linear increase.Under moderate grazing，the carbon，nitrogen，and phosphorus storages of S. baicalensis and P. bifurca were the highest.(4)L. chinensis，A. frigida，S. baicalensis，and P. bifurca were all restricted by nitrogen under different grazing intensities，while C. duriuscula was restricted by N under heavy grazing condition.Compared with grazing areas，S. baicalensis in non-grazing，light grazing and moderate grazing areas was restricted by phosphorus.This study shows that overgrazing reduces the carbon，nitrogen，and phosphorus storages of dominant species L. chinensis，and increases the carbon，nitrogen，and phosphorus storages of degradation indicator species A. frigida and P. acaulis.Appropriate grazing is beneficial to improve grassland phytochemistry，measurement balance and management level.
