Abstract: In order to find the effect of soil enzyme activities under different vegetation restoration in Hilly Loess Plateau, seven kinds of soil enzyme activities and physicochemical properties were studied. In this study, six long trial sites located in Zhifanggou Catchment were studied, and a farmland was chosen as the references. The results showed that soil physical and chemical properties were poor in slope farmland, but vegetations recovery can increased them apparently. After 30 years of de-farming and vegetation recovery, soil urease, phosphatases, invertase, cellulose and catalase, respectively, increased by the percentage of 33%~213%, 275%~394%, 70%~210%, 24%~48% and 32%~96% as compared to the farmland, while polyphenol oxidase decreased by the percentage of 23%~29% and amylase had no obvious effect. Different types of vegetation restoration are different in improving soil enzyme activities. The significant relationships were observed between phosphatase, invertase, cellulose, polyphenol oxidase and physical and chemical properties of soil. We think that the four kinds of soil enzyme activities can be used as indicators of soil quality.
