为了掌握土地整理后烟田土壤基本养分的变化情况，以衡南烟区宝盖镇车陂村土地整理烟田为对象，通过实地采样与分析，对土地整理未干扰区和干扰区土壤的基本性状进行对比分析。结果表明：土地整理后强酸性和有机质含量亏缺的土壤比例增加，土壤全氮、全磷、全钾含量均有所降低，相应的碱解氮、有效磷和速效钾的含量也随之降低；除了全钾含量外，干扰区的其余各项指标的变异系数均比未干扰区的大。这表明土地整理会在一定程度上增大土壤肥力指标的变异系数，导致土壤肥力退化。

In order to understand the changes of nutrients in tobacco field soil,the paper took tobacco fields of land consolidation in C hebeivillage,B aogaitow n,H engnan tobacco area as the study object,com pared and analyzed basic characteristics of undisturbed and disturbed soilofland consolidation.The results revealed thatthe proportion ofhighly acidic soilw ith low organic m attercontentincreased afterland consolidation;the contentsoftotalnitrogen,totalphosphorous and totalpotassium in the soildecreased,and correspondingly,the contents ofavailable nitrogen,effective phosphorous and rapidly available potassium decreased;variation coefficients ofallindices except totalpotassium in disturbed soilw ere largerand those ofundisturbed soil,w hich revealed thatland consolidation could cause the increase ofvariation coefficientsofsoilfertilizerindicesto a certain degree and lead to the degradation ofsoilfertility.
