摘要：共和盆地高寒沙区植被恢复区4种典型人工灌木林是柠条（Caragana korshinskii）、沙棘（Hippophae rhamnoides）、沙柳（Salix psammophila）和乌柳（Salix cheilophila）。土壤有机碳密度调查研究表明，不同灌木群落类型下的土壤有机碳密度（0 - 100 cm）由大到小是：沙棘9.42 kg/m^2、沙柳6.73 kg/m^2、乌柳6.06 kg/m^2、草地4.56 kg/m^2、柠条3.67 kg/m^2。不同灌木林地0 - 100 cm土壤质地和分层状况不同，土壤有机碳含量随着土壤深度增加而减少，表层（0 - 10 cm）含量最高。与对照样地草地相比，位于丘间地的林地土壤有机碳含量均有不同程度的提高。
There were four kinds of typical shrub plantations in vegetation recovery areas of alpine desert in Gonghe Basin： Caragana korshinskii, Hippophae rhamnoides, Salix psammophila and Salix cheilophila. Results indicated that soil organic carbon density in the profile of 0 – 100 cm was 9.42, 6.73, 6.06, 4.56 and 3.67 kg/m^2 for the shrub community of Hippophae rhamnoides, Salix psammophila, Salix cheilophila, Grassland, andCaragana korshinskii, respectively. The soil under Hippophae rhamnoides had the largest content of organic carbon, followed by Salix psammophila, Salix cheilophila, and Grassland, and the soil under Caragana korshinskii had the lowest content of organic carbon. Both soil texture and stratified conditions changed with soil depth in the range of 0 – 100 cm under different types of community. Soil organic carbon density decreased with the increasing soil depth, and the soil in top layer of 0 – 10 cm had the greatest content of organic carbon. The soil organic carbon content at the bottom slope of forest than that of grassland.
