Other Abstract



The soil enzyme is a key criterion for evaluating soil efficiacy of vegetation restoration,as it is an important indicator of soil quality and function. The objectives of this study are 1)to estimate the effects of vegetation restoration on soil enzyme activity,2)to determine the correlationship between soil fertility and enzyme activity by comparing the five alternatives of vegetaion restoration. The results showed that soil enzyme activity of sucrase, catalase and alkaline phosphatase activity had significantly increased after vegetation restoration than that of barren land, and its magnitude followed the order of Tamarindus>Jatrophacurcas L.>Azadirachta indica. The soil enzyme activity in the rhizosphere of hedge acacia and Azadirachta indica was higher than in non-rhizosphere. Countour planting was found having an important role in preserving soil fertility to create a favorable environment for microorganisms and to enhance soil enzyme activity. These results suggested that different vegetation restoration practices and planting methods had distinct influences on soil enzyme activity. The enzyme activity had closely related with the soil fertility for various vegetation restoration practices, particularly for the relationship between soil organic matter, total nitrogen and soil sucrase, catalase and alkaline phosphatase activity. Thus,we concluded that indicator of soil enzyme activity was reliable for efficiency assessment of vegetation restoration
