摘　　要：土壤养分具有变异性,其变异性特征能够反映区域生态功能和景观格局的动态变化,是土壤的重要属性之一。本文从土壤养分空间变异的研究意义出发,通过对相关文献的阅读分析,简述了国内外关于土壤养分空间变异研究的发展历程和研究现状,分析了土壤养分空间变异的来源,简述了地统计学、地理信息系统(Geographic Information System, GIS)、遥感以及人工神经网络等研究方法在土壤养分空间变异研究的应用现状,并对目前研究所存在的问题进行了剖析,在此基础上对未来的研究方向进行了展望。Soil nutrients have variability, which can reflect the dynamic changes of regional ecological function and landscape pattern, so it is one of the important properties of soil. Based on the research significance of soil nutrient spatial variation, we summarized the development process and status of soil nutrient spatial variation research at home and abroad, and analyzed the sources of soil nutrient spatial variation through reading and analyzing relevant literature in this paper. The application status of geostatistics, Geographic Information System(GIS), remote sensing and artificial neural network were also briefly introduced, and the existing problems were analyzed. On these bases, the future research direction was prospected.
