The different land use plots (i.e., wasteland, pinewood land and grassland in this study) of red soil hilly region were selected as the research regions.On the basis of detecting the effects of land use type on the distribution properties of soil labile organic carbon and herb biomass, this research investigated the quantitative relation between soil labile organic carbon and herb biomass under the different land use types.The results showed that land use types had significant effects on the distribution of soil readily oxidized organic carbon(ROC), dissolved organic carbon (DOC), microbial biomass carbon (MBC) and herb biomass at plot scale, and all labile organic carbon components and herb biomass of grassland plot were higher than those of wasteland and pinewood land plots.Quantitative analysis showed that the soil labile organic carbon components, which had statistically affected the herb biomass of the three plots, were DOC (wasteland plot), ROC (pinewood plot), DOC and MBC (grassland plot).In addition, the influence of DOC on herb biomass in wasteland plot was generally through SOC.
