摘　　要：以京东板栗主产区迁西县为研究区域,对土壤中20种植物必需和有益营养元素的背景值及影响元素背景值分布的主要因素进行了分析。结果表明,迁西县土壤中Mg、Fe、Cu、Na、Co和Ni的含量相对富集,而Ca、S、B、Mo和Se的含量相对贫乏,P、K、Ca、Mo和Ni在全县水平范围内的变异性较大。进一步分析发现,成土母质类型是影响矿质元素背景值含量及分布的最基本和最主要的因素,土壤质地、土壤类型和有机质含量是影响背景值的重要因素,而海拔高度对其影响较小。This paper analyzed the background value of 20 kinds of essential and beneficial plant elements in Qianxi County,and discussed the main affecting factors.The results indicated that the contents of soil Mg,Fe,Cu,Na,Co and Ni were relatively enriched,but Ca,S,B,Mo and Se were relatively poverty,and the distribution of P,K,Ca,Mo and Ni had larger variability.The analysis of influencing factors on soil background values showed that the type of parent rocks was the most basic and main factor,soil texture,soil type and soil organic matter content also had important effect,while the altitude had little impact on it.
