Abstract:: Soil nutrient is the material foundation for vegetation restoration and growth. The method of space representing time scale is used to examine the soil nutrient dynamics with moderate rocky desertification as background in the different reclaimed terms at Hawks Town, Zhongshan District of Liupanshui City. Standard deviation decision-making is used for different period of forest rehabilitation from slope agricultural land on the restoration of soil nutrients for a quantitative evaluation. Correlation analysis showed that soil nutrient has positive correlation with period of the forest rehabilitation from slope agricultural land. The results of quantitative evaluation showed that the soil nutrient index of slope converted farmland is 6～14 times higher than the moderate rocky desertification, and its soil nutrients could be restored significantly and increased with the growing of the abandoned terms.
