Knowledge and evaluation of soil fertility is a vital component of developing sustainable agronomic practices. Theobjective of this study is to identify soil parameters that are sensitive to changes in the soil and indicative of soil functions，using the second soil survey data. The mean soil organic matter，available nitrogen，available phosphate，and availablepotassium are 44.32g/kg，195.91mg/kg，29.05mg/kg，184.56mg/kg.Six principal components accounted for 64.1% of variability among rotations. The soil parameters loaded within these components highlighted the strong influence oncarbon and nitrogen cycling indicated by higher soil organic carbon，total nitrogen. Clustering analysis is good method forfertilization guidance in different town with similar fertilitycharacteristis.A better fertilizer application practice base on theresult applying organic fertilizer combined with inorganic fertilizer with reduced nitrogen and phosphate applicationrate，encouraging crop strawreturning，will promote the crop production and soil quality.
