| 摘 要： | 应用地统计学方法,结合GIS技术对新疆生产建设兵团农一师16团土壤表层（0～20 cm）有机质、速效氮、速效磷、速效钾4种养分要素的空间分布特征,进行了定量分析,并绘制出这几种元素的空间分布图.结果表明,4种养分要素的空间相关程度均属于中等的空间相关性,变异尺度在5～9 km范围内.通过养分分布图来看,有机质和速效氮的相关性较大,含量属于中等偏低;速效磷和速效钾含量则较高.分布情况与实地的产量和地形地貌基本一致.

| Abstract: | Statistical method combined with GIS was applied to analyze the spatial variation of soil nutrients including soil organic matter,available N,available P and available K in topsoil(0-20 cm) on Regimental Farm 16,Agricultural Division 1,Xinjiang Production and Construction Corps.The spatial variation of these soil properties was quantitatively analyzed by quantitative methods and the spatial variation of soil nutrients was mapped.The conclusions were drawn from the analysis:The spatial correlation of these four soil nutrients were moderately dependent.The ranges were between 5-9 km.The soil organic matter and available N had great correlation.The contents were below medium-level and contents of available P and available K belonged to high-level.The distribution was consistent with local yield and landform. |
