摘要	Soil respiration (SR) has been demonstrated to be affected by nitrogen (N) enrichment. However, most studies examine the effect of N enrichment on SR using only two levels of N treatments (i.e. control vs N enrichment). Current understanding of SR responses to varying rates of N enrichment remains unclear. A field manipulative experiment with eight levels of N addition (0, 1, 2, 4, 8, 16, 32, 64 g N m(-2) yr(-1)) was performed to examine SR responses to N enrichment rates in a temperate steppe of northern China. A nonlinear decrease in SR along N addition gradient was observed in the temperate steppe. N addition decreased SR mainly through reducing soil moisture in this study. These findings facilitate accurate estimation of soil C flux in the scenario of intensified N enrichment.
