为研究山东植烟土壤腐殖质的组分及分布特征，对临朐和蒙阴典型植烟土壤的耕层和剖面各层次腐殖质组分特征进行了分析。结果表明，临朐和蒙阴土壤腐殖质碳平均含量分别为7.99和5.83 g/kg，腐殖酸碳平均含量分别为5.57和4.16 g/kg，胡富比分别为1.27、2.28。褐土性土、淋溶褐土、棕壤性土、钙质粗骨土、褐土和酸性粗骨土中的腐殖质碳含量依次递减。腐殖质含量及各组分含量随着土壤深度的降低，呈逐渐降低的趋势，从表层到中层降低幅度较大，以后降低较缓慢；土壤的胡富比在垂直方向上分布为先降低后升高，最后降低的趋势。

Soil humus fractions characteristics were analyzed for samples taken from Linqu and Mengyin Counties to study the humus composition and distribution characteristics in typical tobacco planting soils in Shandong. The results showed that soil humus carbon content was 7.99 and 5.83 g/kg, humic acid carbon content was 5.57 and 4.16 g/kg, H/F were 1.27 and 2.28 in Linqu and Mengyin, respectively. Humus carbon content, from high to low, was cinnamon soil>leaching cinnamon>brown soil>calcareous regosols>cinnamon soil>acidic regosols. The maximum was 8.21 g/kg and the minimum was 3.92 g/kg. Humus content and the content of each component in the two counties gradually decreased with soil depth, and decreased rapidly from the surface to the middle, then decreased slowly. H/F decreased firstly, then increased, finally decreased with soil depth in two counties.
