摘　　要：研究基于ArcGIS技术,应用地统计学方法对献县金丝小枣产区土壤元素空间分布特征进行描述,并探讨元素分布与人体健康的关系。结果表明:全量钾、全量铁、全量锌、全量硒和全量镍的土壤样本均呈正态分布,5种元素均为中等变异强度,且彼此间基本上都呈显著的相关性。地统计学的空间结构分析表明,全量钾、全量锌和全量镍的空间相关性都比较强烈,而全量铁和全量硒则呈现中等程度的空间相关性。等值线图显示,各元素的分布与地形之间有一定程度的空间相关性。各元素在研究区土壤中的含量均处于安全水平,可以根据元素在研究区的空间分布来参考规划金丝小枣的种植,从而为人们提供比较安全有效的矿质元素摄入途径。A study on spatial distribution of soil elements on the field scale of Xianxian and relationship between soil elements and human health. Total K, Total Fe, Total Zn, Total Se and Total Ni were all showed normal distribution and intermediate variability,and there was a significant correlation between these elements. The spatial variability showed that there was a significant correlation between Total K, Total Zn and Total Ni,and Total Fe and Total Se were medium related. The distribution of elements was related in the Contour Map. And we could planning the planting of Ziziphusjujuba according to these five elements which was in safety level,and then supplying us a safety mineral elements absorbing ways.
