为了弄清我国清香型典型烟区土壤腐殖质组成特征，对福建、云南、四川3大烟区19个县52个典型样点耕层土壤腐殖质组分碳量进行了测定和分析。结果表明，总体上，清香型烟区腐殖质及其组分碳量均符合正态分布，土壤腐殖质碳、胡敏素碳、胡敏酸碳及富里酸碳量平均分别为16.3、12.3、1.7、2.3 g/kg，胡富比平均为0.75。腐殖质及其组分随土壤发育程度的增强而提高，在土壤类型上体现为水稻土>红壤>紫色土；受种植制度的影响，清香型烟区水稻土胡敏酸碳量以福建烟区显著高于其他2个烟区，胡富比福建烟区最高，云南烟区最低，四川烟区居中，其值分别为0.92、0.67、0.70；区域土壤腐殖质及其组分的平均值受样本土壤类型组成的影响，在进行腐殖质及其组分的区域整体评价时，应考虑到样本组成。

In order to understand characteristics of humus in clean aroma tobacco-growing regions(CATGR), the soil humus and its composition of 52 soil samples from Yunnan, Fujian, and Sichuan provinces with typical CATGR were analyzed. The results showed that humus and carbon contents of the soils in CATGR conformed to normal distribution. The carbon content of humus, humin, humic acid and fulvic acid were 16.3, 12.3,1.7 and 2.3 g/kg, and HA/FA was 0.75 on average. Humus and compositional carbon contents increased with soil development degree. The soil type from high to low as follows:Paddy soil>Red soil>Purple soil. The carbon content of humic acid in Fujian were the highest of paddy soil in CATGR, the soil HA/FA ratios in Fujian was the highest, and Sichuan was the lowest. There were significant differences of humus and compositional carbon contents on average among different regions. The averages of humus content and composition could be influenced by soil type of the samples, therefore, the assessment should consider the sample composition.
