| Abstract: | Aims Anthropogenic disturbances and climate change have resulted in large scale degradation of grasslands across the landscapes in Nei Mongol. Fertilization, especially with nitrogen (N) addition, has been proposed and applied as an important management practice to promote primary production for these degraded grasslands. In this study, we examined the changes in plant diversity and biomass at three levels of degradations with N addition. |
