摘　　要：为明确云南丽江植烟土壤养分状况,本文采用主成分分析法和模糊数学隶属度函数模型对丽江市5个植烟县2011—2013年521个土壤样品数据进行分析。结果表明:丽江植烟土壤p H值适宜,有机质含量平均为40.35 g/kg,较丰富,全氮和碱解氮含量偏高,全磷和速效磷含量比较充足,全钾和速效钾含量较高。植烟土壤肥力综合指标平均值为0.646,约85.99%的土壤肥力处于中等及其以上水平,具备与优质烤烟生产相适应的土壤条件。Based on the 521 soil samples data from 2011 to 2013 in Lijiang,the methods of principal component analysis and membership function of fuzzy mathematics were used to estimate the status of soil fertility by means of estimating integrated fertility index. The results showed that p H value was generally moderate. The average content of soil organic matter content was 40. 35 g / kg,which was sufficient. Soil total N and available N were slightly high. Soil total P and available P were generally sufficient. Soil total K and available K were high. The average of integrated fertility index was 0. 646,soil with fertility at medium and higher grade accounted for 85. 99%.
