Abstract】The Beijing-Tianjin Sand Source Control Project (BTSSCP), a national ecological restoration project, was launched to construct an ecological protection systemin the Beijing-Tianjin sand source areasto reduce dust hazards. The carbon sequestration dynamics can be used to assess the ecological effects of an ecological restoration project. Here, we conducted vegetation and soil study to assess the carbon sequestration in the plantations with 10 years old stands inBeijing-Tianjin sand source areas. The results at the site scales indicated that theaverage net increase of plantation ecosystem carbon stock was 33.8 Mg C ha-1, with an annual increase rate of 3.38 Mg C ha-1 yr-1.The average net increase ofcarbon varied among regions,vegetation types, and forest managementactivities.Soil bulk density in the top soil decreased slightly after 10-year implementation of the project. Coniferous forests and shrubs are suitable plant species for sand source areas. Natural restoration in the plantations is a practical and feasible and promising approach for enhancing ecosystem carbon sequestration potential.
