To evaluate the impacts of different revegetation methods on soil nutrients，this study combined laboratory analyses with field surveys in two watersheds: one subjected to artificial restoration (AR) and the other to natural recovery (NR)． The results show that，after 11 years of restoration，the soils in the AR watershed were more acidified than those in the NR watershed． In the soil of 0-60 cm，total N，total P，and total K contents in the AR watershed soils were higher than those in NR watershed soils，with greater coefficients of variation． In contrast，the NR watershed accumulated more soil organic carbon of both heavy and light fractions，in the same soil layers． The contents of light fraction soil organic carbon differed most between the surface soils of the two recovery methods，while much less in the lower soil layers． The coefficients of variation of the organic carbons fraction in the soils of the AR watershed were higher than those of the NR watershed soils． The results indicate that the processes of artificial restoration and natural recovery accumulate soil N，P，K and organic carbon in different ways．
