对武都区耕层土壤进行取样,测试分析150个土样的铁、锰、铜、锌、硼、硫和硅共7项指标.对测试结果根据采样经纬度对应到土壤图,再采用径向基函数插值法进行空间插值,获取27个土种各微量元素平均值和全区各微量元素平均值.有效铁石渣土含量最高,浅红土最低;有效锰亚高山灌丛草甸土含量最高,粗骨质碳酸盐褐土含量最低;有效铜含量耕种砂质黄棕壤最高,羊血土最低;有效锌绵黄土含量最高,浅红土最低;有效硼含量山地耕种草甸土最高,石渣土最低;有效硫含量砂砾质碳酸盐褐土最高,浅红土最低;有效硅含量亚高山灌丛草甸土最高,麻黄土最低为.武都区土壤微量元素含量普遍低,且空间分布不均.

The contents of 7 indicators included Fe,Mn,Cu,Zn,B,S and Si are analyzed of 150 soil samples which are sampling from the topsoil of Wudu district . According to the latitude and longitude of sampling points,the results of test could correspond to the soil map,then using radial basis function interpolation method for spatial interpolation,got the trace elements average value of 27 kinds of soil species and the trace elements average value of this region . The content of available Fe of lithosol is highest, and the lowest is shallow laterite . The content of available Mn of subalpine shrub meadow soil i s highest,crude bone carbonate cinnamon is lowest . The content of available Cu of farming sandy yellow brown is hghest,the yangxuetu is lowest . The content of available Zn of cotton loess is highest,the lowest is shallow laterite. The content of available B of mountain cultivated meadow soil is highest,the lithosol is lowest. The content of available S of sandy and gravelly carbonate cinnamon,and the minimum is shallow laterite. The content of available Si of subalpine shrub meadow soil is highest,th hemp loess is minimum. The contents of soil trace elements of Wudu district are generally in a lower level, and the space distribution of trace elements are uneven.
