摘　　要：在分析四川省凉山州植烟土壤肥力指标的基础上，建立了植烟土壤肥力适宜性评价指标体系，并运用模糊数学和主成分分析法对土壤肥力水平进行了评价及分级。结果表明：（1）凉山州植烟土壤pH适宜，土壤有机质、碱解氮、速效钾含量多处于中等偏低水平；有效磷，交换性钙、镁处于中等偏高水平；有效铁、锰、锌、钼均以很丰富等级为主，水溶性硼与水溶性氯多处于中等偏低水平，而有效钼在各等级之间均有一定比例分布。（2）凉山州植烟区土壤适宜性指数变幅为0．25—0．95，平均值为0．64，变异系数为21．87％。（3）根据土壤适宜性指数（SFI）将凉山州土壤肥力分为高、较高、中等、较低和低5个等级，属于中等以上的植烟区土壤所占的比例为94．94％，无样品分布在低水平。其中布拖县SFI最高，喜德县SFI最低，其余地区SFI居中。The index system of soil fertility adaptable for tobacco was established based on analysis of the physical and chemical properties of soil samples collected from Tobacco-planed areas in Liangshan, Sichuan Province. The fertility level was evaluated and classified by fuzzy and analysis. It was found that pH in the Liangshan tobacco-planed areas were suitable. The soil organic matter and nitrogen were abundant, but the phosphorus and potassium were shortage. The exchangeable calcium and magnesium were higher. The microelements of available zinc, copper, iron, manganese and molybdenum were higher, but the available boron and water soluble Chloride was deficient. （2）The SFI ranged from 0.25 to 0.95 with the mean of 0.64 and coefficient variation of 21.87%. （3） The soil fertility was classified into 5 groups of higher, high, medium, low and lower based on the SFI, and SFI was in the extent of 0.4-1.0 for 94.94% of the soil samples.
