Abstract
Taking four types of slopes as test objects this paper measured their, soil nutrient and soil enzyme activity. The results showed that variation of soil nutrients in different slopes is obvious; soil enzyme activity is also a significant difference between different slopes. The soil of A slope (natural secondary forest ) was the highest in activity of urease, invertase, neutral phosphatase and catalase, the lowest in D(wasteland)slope except catalase. There were extremely significant positive correlations among soil urease activity, invertase activity and neutral phosphatase activity. Significant positive correlations were observed between soil urease activity, invertase activity, neutral phosphates activity and organic matter, available N, total N. It suggested that enzymatic activity could be used to indicate and estimate soil fertility of artificial remediation slopes. Combined with and community structure and community characteristics of vegetation on the sanmpled slops, soil enzyme activities could be used to measure the degree of vegetation restoration in the disturbed area.
