摘　　要：应用传统统计学、地统计学和GIS技术相结合的方法,分析了尧都区神刘村汾河水灌溉区耕层土壤养分的空间变异规律,绘制了表达这些土壤特性随机性和结构性的半方差图和空间分布图。结果表明:土壤有机质、全氮、全磷、全钾、有效氮、速效磷、速效钾、有效铜、有效锰、有效锌和有效铁含量范围分别为45.62～9.61g·kg-1、1.82～0.06g·kg-1、1.19～0.26g·kg-1、19.86～11.18g·kg-1、197.62～37.34mg·kg-1、28.50～0.40mg·kg-1、488.89～102.22mg·kg-1、3.12～0.38 mg·kg-1、6.16～1.39 mg·kg-1、4.23～0.42 mg·kg-1、19.82～4.18mg·kg-1。与全国第二次土壤普查养分分级表的比较,调查区土壤有机质、全氮、全钾的均值处于二级水平,全磷、水解氮和有效锌的均值处于二级水平,土壤速效钾的均值处于一级水平,其含量均可满足农作物的生长需求,但该地区土壤有效锰的均值处于五级水平。在研究区内,土壤各养分的空间变异程度均属于中等强度。有效锰的空间分布为纯块金效应,说明在采样范围内不存在空间相关性。水解氮和有效铁的空间分布体现为中等空间相关性,其余养分的空间分布均体现为强空间相关性。Based on the traditional statistics,Geo-Statistics and GIS, the spatiation variation rules of the Fen River Irri- gation Farmland Nutrients in Shen liu village Yao du district was studied. The spatial distribution maps and semivario- grams that can erplicitly depict the random and structural of soil property were drawn. The result showed that the con- tent ranges of soil organic matter, total N, total P, total K, available N, available P, available K, available Cu, availa- ble Mn, available Zn and Fe were 45.62 to 9.61 g · kg^-1 , 1.82 to 0.06 g · kg^-1 , 1.19 to 0.26 g · kg^-1, 19.86 to 11.18 g· kg^-1, 197.62 to 37.34 mg· kg^-1, 28.50 to 0.40 mg · kg^-1, 488.89 to 102.22 mg· kg^-1, 3.12 to 0.38 mg· kg^-1 6.16 to 1.39 mg· kg^-1, 4.23 to 0.42 mg· kg^-1, and 19.82 to 4.18 mg· kg^-1. Compared with the sec- ond national soil survey nutrient INES, the mean value of available K in the investigated area soil Organic matter, total N and total K at the third level, the mean value of total P, available N and available Zn at the second level, the mean of potassium at the first level, all meet the needs of the crops. But the mean value of available Mn at the fifth level in the research area, exhibited moderate spatial variability. The available Mn exhibited weak spatial correlation. The available N and available Fe exhibited moderate spatial correlation, and others exhibited strong spatial correlation.
