Unexpectedly, 11 NH4+-N/NO3--N (NH4NO3) significantly improved the positive response of plant community ANPP to precipitation (it had the biggest slope value). Our results suggest that precipitation was the main determinant of the influence of NH4+-N/NO3--N ratios on plant community ANPP. Therefore, the results of our study showed that without referring to NH4+-N/NO3--N ratios and precipitation, models using NH4NO3 enrichment may overestimate the positive effect of atmospheric N deposition on ecosystem ANPP in semi-arid ecozones.Seabi
