摘　　要：为揭示隆回县烟区植烟土壤有机质含量分布状况及其影响因素,采用地统计学方法分析该烟区植烟土壤有机质含量分布及与影响其分布的土壤类型、土壤质地、p H等因素。结果表明：（1）隆回县烟区植烟土壤有机质含量较高,变幅为5.37~84.64 g/kg,变异系数为28.09%,处于适宜范围内的样本占21.09%,空间分布上呈现从北向南增加趋势。（2）不同乡镇之间的植烟土壤有机质含量差异达极显著水平,6个主产乡镇植烟土壤有机质含量属较高水平,且处于中等及低变异。（3）不同植烟类型土壤的有机质含量差异达极显著水平,红壤和黄壤的有机质含量属适宜水平,其他类型土壤的有机质含量属较高水平。（4）不同土壤质地的植烟土壤有机质含量差异达显著水平,烟区植烟土壤有机质含量平均在32.03~34.21 g/kg。（5）不同p H的植烟土壤有机质含量差异极显著,随p H升高而升高的趋势,且p H〉7.0的植烟土壤有机质含量较高。In order to reveal the distribution of organic matter contents in tobacco growing soils and itsinfluencing factors in Longhui, spatial distribution of organic matter contents, and the distribution influentialfactors, such as soil type, soil texture, p H and so on, were analyzed. Results showed as follows：（1） organicmatter contents in the tobacco soil were higher for tobacco cultivation with amplitude of 5.37-86.46 g/kg andvariation coefficient of 28.09%, organic matter contents of about 21.09% of the soil samples were fit for tobaccocultivation;（2） significant differences were found among the different villages and towns for the contents oforganic matter, the soil organic matter contents in the 6 main tobacco planting villages and towns were higher,and of medium variability and low variability;（3） significant differences were found among the different soiltypes, the contents of organic matter from red soil and yellow soil had a suitable level, and other types of soilhad a higher contents of organic matter;（4） significant differences were found among the different soil texture,the average organic matter content in the tobacco soil was 32.03-34.21 g/kg;（5） significant differences werefound among the different soil p H, the organic matter contents increased with the rise of the p H value, and theorganic matter contents was higher in soil which had pH7.0 in Longhui.
