Abstract:
The spatial variability character of trace elements Cu,Zn,B,Moin 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.
