Increasing nitrogen (N) deposition has been reported to result in positive, negative, and neutral impacts on soil oxidative enzyme activities, which are associated with lignin degradation. The oxidative enzyme activities are usually high and stable in desert ecosystems. Therefore, the exploration of how these enzymes respond to N addition is critical to evaluate the carbon transformation in desert ecosystems. We present the seasonal variations in oxidative enzyme activity and their responses to simulated N deposition in the topsoil (0–5
