| 摘 要： | 根据凉山烟区5种类型土壤的9种肥力指标数据,应用主成分分析法对该区的土壤肥力进行了综合评价,得出的3个主成分的累积贡献率为86.96%。3个主成分为养分因子(由有机质、有机总碳、全氮、全磷、碱解氮、速效磷含量组成)、钾因子(由全钾和速效钾含量组成)和pH因子(由pH值组成)。不同类型土壤肥力的综合得分显示为:黄壤>紫色土>红壤>水稻土>黄棕壤。 |

| Abstract: | The principal component analysis in the SPSS statistical software was adopted to conduct a comprehensive evaluation of soil fertility according to 9 fertility indicators of 5 soil types in Liangshan tobacco growing areas.The cumulative contribution rate of three main components was 86.96%.The original indicators information could be explained basically by these three main components.The three main components were: ① soil organic matter,organic total carbon,total nitrogen,total phosphorus,available nitrogen,available phosphorus content;② total potassium and available potassium content;③ pH-value.The integrated fertility score of various soil types showed the following order: yellow soil> purple soil> red soil> paddy soil> yellow brown soil. |
| Keywords: | Liangshan Flue-cured tobacco Principal component analysis Soil fertility Comprehensive evaluation |
