摘　　要：采用模糊数学和多元统计分析原理计算出代表曲靖土壤肥力状况的IFI值,运用地统计学对其进行趋势和空间分析。结果表明:曲靖烟区土壤pH值,有机质、全氮、全钾、有效硫、水溶性氯含量适中,碱解氮含量较高,有效磷、全磷、有效钾含量丰富。大部分植烟土壤肥力处于中等水平和较高水平,土壤肥力状况良好。罗平县、马龙县、师宗县、宣威市土壤肥力指标总分较高,富源县与会泽县土壤肥力指标总分最低。烟区土壤肥力随着海拔的增加有减少的趋势。Soil nutrient status in Qujing area was comprehensively evaluated in order to establish a theoretical basis for tobacco soil and hence to improve tobacco leaf quality and characteristics.Fuzzy math and multivariate statistical analysis were adopted to calculate soil nutrient which expressed by value of IFI.Statistical methods and GIS technology were applied to analyze their trend and spatial distribution.Results indicated that pH and content of O.M.,total N,total K,available S,water soluble Cl were moderate...
