摘要

To investigate the bacterial functional diversity regarding soil carbon metabolism in Sanjiang Plain wetlands, the top soils (0–20 cm) of three different land use types were collected in Sanjiang Plain, China. The distribution and variation of carbon source utilization was assessed by the Biolog microplate method. The results showed that the physicochemical properties of the soil were significantly different between the three land use types, wetland, farmland and forest (P 0.05). Principal component analysis (PCA) indicated that soil bacterial carbon utilization revealed obvious spatial variation, suggesting the bacterial metabolism diversity could be reflected in the use of carbohydrates, amino acids and carboxylic acids, particularly carbohydrates. In addition, soil physicochemical properties and vegetation composition were important factors modifying soil bacterial composition and functional activity in different land use types.
