摘要	The details of how vegetation rehabilitation affects soil enzyme activities via changes of soil nutrients are unclear. To investigate how soil carbon and available nitrogen affect soil enzyme activities during the process of vegetation restoration, a factorial experiment was conducted with vegetation cover and nitrogen addition on degraded lands, and then a carbon addition experiment was performed with soil incubation. Soil enzyme activities were significantly higher under vegetation plots than those under bare plots and were highly related to the soil total carbon and nitrogen concentrations. For soils from bare plots, C addition increased beta-1,4-glucosidase (BG) activities, beta-N-acetyl glucosaminidase (NAG) activities, leucine aminopeptidase (LAP) activities and acid phosphomonoesterase (AP) activities by 93%, 784%, 268% and 272%, respectively. By comparision, C addition only increased activities of BG, NAG, LAP and AP by 6%, 54%, 45% and 214% for soils from vegetation plots, respectively. Furthermore, the interaction between C and N significantly affected the activities of AP and BG. These findings indicate that the elevation of enzyme activities during vegetation rehabilitation is mainly driven by the relaxation of C-N limitation for microorganisms.
