| 摘 要： | 测定了36个土样的有效养分(碱解氮、有效磷、有效钾、有效锌)和有机质的含量，结果表明，碱解氮、有效磷、有效锌、有机质和有效钾含量的空间自相关性较强。采用Kriging指数模型的拟合效果最佳。对试验点空间预测结果说明，土壤碱解氮、有效磷、有机质含量的空间变异程度大，而有效钾、有效锌含量的空间变异程度小。

| Abstract: | 36 soil samples were sampled in Kuitun Farm and soil alkali hydrolyze N,soil available P,soil available K,Soil available Zn and soil organic matter content were tested in the study.Results indicate that all soil nutrition is with medium to high intensity of spatial self-correlation.Among several models,Kriging exponential model is the best model to predict soil nutrition spatial variability.Spatial prediction indicate that spatial variability is bigger in soil alkali hydrolyze N,soil available P and soil organic matter but in soil available K and soil available Zn,the spatial variability is small. |

| Keywords: | soil nutrition spatial variability spatial self-correlation |
