In order to understand the change characteristics of soil organic in the recovery process of Pinus sylvestris var. mongolica in Mu Us sandy land, we used the space-for-time substitution method and took the bare land as a contrast, the Pinus sylvestris var. mongolica communities afforested in 1960s, 1970s and 1980s under similar site condition were selected as the sites. The temporal changes and vertical variation characteristics of soil organic matter contents in Pinus sylvestris var. mongolica forest lands were studied, and abundance and deficiency status were further analyzed. The results showed that:(1) the contents of soil organic matter of lands with different years of Pinus sylvestris var. mongolica growth decreased gradually with the increase of soil depth, showing the obvious surface enrichment; (2) the soil organic matter content in Pinus sylvestri var. mongolica forest increased first and decreased later with the increase of forest age, but the change range gradually decreased; (3) the contents of soil organic in Pinus sylvestris var. mongolica forests with different recovery years in the study area increased compared with the bare land, but the contents of soil organic matter were still at the deficient level on the whole.
