Taking research sites located at sunny slop with different years of natural vegetation restoration in Ziwuling area as a case study,dynamic changes of soil nutrient and soil enzyme activities following 140 years of vegetation restoration were analyzed.Results showed that after 140 years of vegetation restoration,soil organic matter(SOM),total N(TN),invertase,urease,alkaline phosphates and catalase activities obviously increased in both 0~20 cm and 20~40 cm layers of soil profile with an increase of the vegetation restoration year. Compared with corresponding bare land,SOM,TN,soil invertase,urease,alkaline phosphates and catalase activities in 0~20 cm layer of soil profile increased by 23.8%~534.9%、9.2%~300.0%,213.6%~521.5%,40.4%~286.5%,22.7%~232.2% and 3.2%~22.4%,change trend of soil available P of soil profile was fluctuant,soil catalase activity change scop was lower than other three kinds of enzyme.There was remarkable correlation between SOM and TN,available P;soil invertase activity and SOM,TN assumed significant correlation(0.930 and 0.918);the correlation coefficient of soil urease activity and TN is the highest(0.804);there was also very significant correlation between soil alkaline phosphates activity and SOM,TN(0.977 and 0.984);soil catalase activity and TN also presented remarkable correlation,the correlation coefficient reached to 0.996.
