Different sensitivity and threshold in response to nitrogen addition in four alpine grasslands along a precipitation transect on the Northern Tibetan Plateau.

There was no significant effect on alpine steppe in the first 3 years, and aboveground biomass of grasses showed an increasing trend in 2017 (Figure 4 , p = .010).
