- 摘要:
- 运用地统计学方法及ArcGIS软件对河北省麻山药种植主产区表层土壤（0～20 cm）中铜、锌、硼、钼4种微量元素的空间变异特征进行了研究，并利用SPSS软件分析了4种元素之间的相关性。结果表明：4种元素间均呈极显著正相关关系，但不同元素间的相关程度不同。4种元素之间的相关性除了与土壤自身性质、水文地质有关外，还与元素的金属性相关；用Kriging插值对4种元素进行最优估计，通过统计特征值可以发现，土壤中4种微量元素的分布均不成正态分布，其土壤中的含量受到外界人为因素的影响；4种微量元素主要集中在高阳、蠡县2县交汇处，而且沿河道逐次递减分布。侧面反映了2个县土壤的成土过程。
- Abstract:
- The spatial variability character of trace elements Cu,Zn,B,Moin the surface soil(0～20 cm) of main producing areas of the hemp yam of Hebei province were analyzed by the Geostatistics method combine the ArcGIS software.The correlation between four kinds of elements were analyzed by SPSS software.The results indicated that four kinds of trace elements showed significantly positive correlation，but the degree of correlation between any two of the four trace elements was different.The correlation between the four elements had relationship with the metallic besides the soil nature and hydrogeological.Using the Kriging interpolation to make a optimal estimation of the four elements，it could found that the distribution of four trace elements in the soil were not normally distributed.The content of the four elements in the soil had been influenced by human.The four trace elements were mainly concentrated in the counties junction，and the content gradually decreases along the river channel.It’s illustrated on the other hand reflected the formation process of the soil.
