英文摘要	Shrubs play a vital role in ecosystem restoration in the desert transition zone, which suffers intensive deserti-fication, land degradation, and nitrogen (N) limitation. To evaluate the effects of different shrub species on soil N availability, transformation, and their seasonal dynamics, we determined mineral N contents and mineralization rates in soils under three common shrub species (Artemisia ordosica Krasch., Caragana korshinskii Kom., and Salix psanunophila C.) and in bare land during the growing season in the desert-loess transition zone in northwestern China. The average contents of soil nitrate N and mineral N were 153% and 55% greater, respectively, and cumulative net N nitrification and mineralization were 101.2 and 121.0 mg Nm(-2) higher, respectively, in soils beneath C. korshinskii than in bare land (P < 0.05) at the 0-10 cm depth over the growing season. The net N mineralization rate in 0-10 cm depth was significantly higher in soils under C. korshinskii than that in bare land during 21 Jun-23 Jul and 23 Aug-15 Oct of the growing season. However, C. korshinskii did not influence soil N metrics at the 10-20 cm depth. The incorporation of A. ordosica and S. psanunophila into bare land did not influence soil N availability or transformation rates. Our results demonstrated that C. korshinskii was more preferable than A. ordosica and S. psanunophila in ameliorating soil N cycling in the desert-loess transition zone.
