| 摘要： |
Wetland soil columns with water overlying and without snowpacks were exposed to freeze thaw treatment (FTT1), freeze-thaw treatment with elevated 2 degrees C (FTT2) and growing-season treatment (GST). We found elevating 2 degrees C under freeze-thaw condition without snowpacks and with water overlying could not significantly influence NH4+-N and NO3--N concentrations in wetland soil solutions (p>0.05). Except for the first treatment cycle and 5-10 cm soil layer, NH4+-N and NO3--N concentrations of GST were not significantly different from that of FTT1 and FTT2 (p>0.05) indicating there might be not significant differences of NH4+-N and NO3--N concentrations in wetland soil solutions between in freeze-thaw season and growing season. |
