摘　　要：分析了凉山烟区植烟黄壤的肥力情况,采用模糊数学和偏相关分析的方法确立了黄壤的综合评价体系,并对各项养分指标进行了丰缺评价和分布分析。结果表明：凉山植烟黄壤整体上有机质含量丰富,碱解氮偏低,速效磷含量丰富,速效钾含量中等,pH显示为微酸性,质地偏粘,交换性钙、镁含量丰富;依据凉山植烟黄壤综合养分指数（IFI）将土壤肥力划分为高、较高、中、较低、低5个等级,有82.27%黄壤处于中等以上水平,变幅为0.3274~1.0000,平均分为0.7417,凉山植烟黄壤在整体上表现出较高的土壤综合养分指数。Based on the investigation of yellow soil fertility in Liangshan tobacco planting area,a comprehensive evaluation system was established by fuzzy mathematics and partial correlation analysis,and the abundance or lack and distribution situations of each nutrient index were analyzed.The results showed that the contents of organic matter,rapid available phosphorus,exchangeable calcium and magnesium were abundant; the content of rapid available potassium was medium; but the available nitrogen content was lower.The pH value of soil showed subacid and the texture was partial viscous.The soil fertility was classified into 5 groups of high,relatively high,medium,relatively low and low based on the IFI value.The soil whose fertility was medium and above occupied 82.27%.Above all,the yellow soil of Liangshan tobacco planting area showed higher comprehensive nutrient index on the whole with the change range of 0.3274 ~ 1.0000 and the average value of 0.7417.
