Abstract:
      Selecting the wetland soil of Caragana aurantiaca Koehne as the research object in Yili valley of Zhaosu County, the distribution characteristics and their intrinsic relationship of activities of soil enzyme (urease activity, invertase activity, catalase activity), and soil labile organic carbon (soil water soluble organic carbon WSOC, soil labile carbon ROC, soil microbial biomass carbon MBC) were studied,the relationships between enzyme activities and soil organic carbon characterization index was analysed. The results showed that the activities of soil enzyme declined with soil depth increasing. with the increasing of the soil depth, the content of the vertical profile of the active organic carbon decreased.Sickle leaf Caragana could improve activities of soil enzyme and content of active organic carbon; Invertase, urease and catalase were significantly correlated with soil labile organic carbon (P<0.01),in conclusion, the soil enzyme played an important role in the migration and transformation of soil active organic carbon.
