摘 要：对广东南雄烟区6个基地单元3种主要土壤类型共534个土壤样品的养分指标进行了测定,分析了各类土壤肥力限制因子,并运用主成分分析法确定各土壤养分指标的权重,通过估算土壤肥力综合指标值（IFI）进行综合评价.结果表明：（1）紫色土呈弱碱性,牛肝土呈中性,砂泥土呈较强的酸性；（2）牛肝土和砂泥土速效氮及有机质含量较高,紫色土二者普遍偏低；紫色土和牛肝土速效钾含量丰富,砂泥土普遍缺钾；3种土壤速效磷含量富足；（3）3种土壤不同程度缺乏硼、铜、锌和氯元素,而锰元素含量富足；紫色土不同程度缺乏铁元素；砂泥土不同程度缺乏钙和镁元素；（4）3种土壤综合肥力指标值（IFI）平均为0.577,变异系数为19.25%,雄州（IFI 等于0.641）和乌迳（IFI 等于0.655）基地单元土壤综合肥力指标平均值处于“较高”偏下档次,其他基地单元则处于“中等”偏上（0.6>IFI>0.5）档次；（5）牛肝土土壤肥力（IFI 等于0.649）处于“较高”偏下档次；砂泥土土壤肥力（IFI 等于0.574）处于“中等”偏上档次；紫色土土壤肥力（IFI 等于0.495）处于“中等”偏下档次.

Abstract： Thirteen nutrient indices of 534 soil samples from six base units,three major soil types in Guangdong Nanxiong tobacco growing areas were determined and soil fertility limiting factorswere analyzed. The principal component analysis method was usedin determining the weights of the indices of soil nutrients. A comprehensive evaluation was conducted by estimating the soil fertility comprehensive index of scalar values （IFI）. The results showed that： （1） The purple soil showed a weak alkaline reaction, and the Niugantu soil was neutral, and the Shanitu soilshowed a strong acid reaction；（2）The contents of available nitrogen and organic matter in Niugantuand Shanitu soil were higher, and those in purple soil were generally low；The content of available potassium in purple soil and Niugantu soil was higher, and the content of potassium in Shanitu soil was deficient；All 3 of soil types were rich in available phosphorus；（3） The three major soil types were lack of boron, copper, zinc and chlorine in various degrees, and rich in manganese； There is a lack of iron element in purple soil, and lack of calcium and magnesium in Shanitu soil；（4） The averageintegrated fertility index （IFI） of the three soil types was 0.577 with a variation coefficient of 19.25%. Xiongzhou（IFI 等于0.641） and Wujing （IFI 等于0.655） base units showed higher soil integrated fertility indices while the other base unitshad "medium" IFI （0.6 > IFI > 0.5）；（5） The IFI of Niugantu soil fertility （0.649） was higher while that of Shanitu soil （0.574） and purple soil （0.495） were lower.
