Abstract:: By means of field and indoor analysis, the change of soil carbon components and carbon pool indices of 7 kinds of land use patterns in the loess hilly region were studied. The results show that the rest of the land use patterns can improve soil carbon sequestration capacity, increase the contents of soil carbon components and soil carbon pool index (CPI) and carbon pool management index (CPMI) compared with sloping farmland; the content of total organic carbon (TOC), labile organic carbon (LOC) and non-active organic carbon (NLOC) increased by 42%~125%, 36%~136% and 31%~161%, respectively, compared with the sloping cropland. In general, the improvement of natural shrubs and artificial trees is the best. The ratios of LOC to TOC in different land use patterns range from 46.00% to 57.29%, and activity (A) is between 0.87 and 1.44. The orchard, natural shrub forest and terrace have the highest A. There is the significant correlation between soil carbon, carbon pool management indices and main chemical indices, which can reflect the influence of different land uses on soil carbon sequestration capacity.
