Description :
Under the Beijing–Tianjin Sandstorm Source Control (BTSSC) program in China, approximately 2.6 million ha of cropland have been converted into 3 plantations during 2000–2010. This study used a space-for-time substitution method to evaluate 4 typical afforestation sites (Populus tomentosa, Armeniaca sibirica, 8a Pinus tabulaeformis, and 24a P. tabulaeformis sites) along with the corresponding control sites. The identified sites in Shanxi Province were used to assess the effects of plant species and afforestation time on soil carbon sequestration and physicochemical characteristics. It is highlighted that the effects of afforestation varied with plant species and afforestation time. Soil carbon, nitrogen, and phosphorus depletion rates were higher in economic forests than in protective forests and were higher in evergreen coniferous forests than in broadleaved deciduous forests.
