摘要:
运用碳库管理指数分析了被恢复后宁南黄土丘陵区不同人工植被对土壤碳库的影响，结果表明植被恢复增加各个土层土壤有机碳含量，但是活性有机碳含量表现不同，草地减少，其他植被与农田土壤活性有机碳含量差异不大。随着栽植年限的延长，土壤有机碳含量在各个土层都增加，且在0～30cm土层内增加的幅度都比较大。但是年限并不能增加土壤活性有机碳含量，说明植被恢复年限增加的是土壤非活性有机碳。植被恢复提高了土壤碳库管理指数，其中天然草地增加更为明显。
Abstract:
The influence of man-made vegetation on carbon pool with C pool management index in southern Ningxia region in Loess Plateau is studied, the results show that vegetation can increase soil organic carbon, but there is different results about active carbon, active carbon in pasture decreased, there is no difference between the other vegetation and cropland. With the number of years, the SOC is improved in horizons, and no changes in active carbon, vegetation can increase soil no-active carbon.
