摘要

•A meta-analysis on the degraded grasslands of the Qinghai-Tibetan Plateau.•More severe degradation for plant growth and soil quality than plant diversity.•Fertilisation improves plant growth and soil quality but limits plant diversity.•Optimal effect is found when jointly using phosphorus and nitrogen.•Climatic factors regulate degradation degree and fertilisers' effect.
