Abstract:: In order to discuss the effects of vegetation type on soil active organic carbon and analyze sensitive degree of active organic carbon to vegetation type. Four indicators regarded as representations of soil active organic carbon were analyzed. In the Dongzigou Basin, Ansai of hilly and gully region of the Loess Plateau, soil samples were collected under different forest vegetation types in the depth of 0—10 cm and 10—20 cm. Then the correlation between soil active organic carbon and indicators of dominant plants among vegetation community were analyzed by stepwise regression analysis. The results show that the contents of both soil organic carbon (SOC) and active organic carbon decrease with the increase of soil depth. The contents in tree-shrub-herb community are the highest among the three vegetation community, while they are the lowest in herbs community. Although soil samples differ in vegetation type and soil depth, the proportion of SOC in microbial biomass carbon (MBC) and dissolved organic carbon (DOC) remain stable. On the other hand, the proportion of SOC in light fraction organic carbon (LFOC) are found varies with vegetation types and soil depth, and the proportion of SOC in the easily oxidized carbon (EOC) were found varies with vegetation types. There is a closer relationship between soil active organic carbon and indicators of dominant plants (biomass and total C) and among these four indicators, MBC has the closest relationship, DOC, EOC and LFOC are followed.
