Quantifying the effects of nutrient additions on soil microbial respiration (Rm) and its contribution to soil respiration (Rs) are of great importance for accurate assessment ecosystem carbon (C) flux.
Nitrogen (N) addition either alone (coded as LN and HN) or in combination with phosphorus (P) (coded as LN + P and HN + P) were manipulated in a semiarid alpine meadow on the Tibetan Plateau since 2008.
Either LN or HN did not affect Rm, while LN + P enhanced Rm during peak growing periods, but HN + P did not affect Rm.
Nutrient addition also significantly affected Rm/Rs, and the correlations of Rm/Rs with climatic factors varied with years.
Soil water content (Sw) was the main factor controlling the variations of Rm/Rs.
During the years with large rainfall variations, Rm/Rs was negatively correlated with Sw, while, in years with even rainfall, Rm/Rs was positively correlated with Sw.
Meanwhile, in N + P treatments the controlling effects of climatic factors on Rm/Rs were more significant than those in CK.
Our results indicate that the sensitivity of soil microbes to climatic factors is regulated by nutrient enrichment.
The divergent effects of Sw on Rm/Rs suggest that precipitation distribution patterns are key factors controlling soil microbial activities and ecosystem C fluxes in semiarid alpine meadow ecosystems.
