  • This paper analyzes the element contents in different topsoil and with the methods of statistics inquired into the element contents and its spatial characteristics in Hetao plain. The results show that the element contents (Al and Fe) of Hetao have significant differences with active elements (Na and Sr), but the heavy metal elements(Cu,Mn,Pb,Zn) display abnormally and variable coefficient is larger, which shows heavily influenced by human activities and acts as the indicator of human industrial activities. Spatial distribution of the elements in topsoil shows that the stable elements(Ca,Mg) in the topsoil have a strong spatial autocorrelation, which reflects that the soil parent material have a great effect on element contents; theoretical model of the element P is linear, this result has something to do with using excess P fertilization in much farmland; heavy metal elements in the topsoil have a medium spatial autocorrelation, which subjects to the small scale factors such as industrial and agricultural production. In Hetao plain, the spatial characteristics of heavy metal element contents show that the northern and southern area are relatively high, and northern area exceeds the southern area, the change from the western to eastern area is not obvious, this phenomenon is closely related to human activities such as local industrial mining, urbanization development, industrial and agricultural production and so on.

Abstract: This paper analyzes the element contents in different topsoil and with the methods of statistics inquired into the element contents and its spatial characteristics in Hetao plain. The results show that the element contents (Al and Fe) of Hetao have significant differences with active elements (Na and Sr), but the heavy metal elements(Cu,Mn,Pb,Zn) display abnormally and variable coefficient is larger, which shows heavily influenced by human activities and acts as the indicator of human industrial activities. Spatial distribution of the elements in topsoil shows that the stable elements(Ca,Mg) in the topsoil have a strong spatial autocorrelation, which reflects that the soil parent material have a great effect on element contents; theoretical model of the element P is linear, this result has something to do with using excess P fertilization in much farmland; heavy metal elements in the topsoil have a medium spatial autocorrelation, which subjects to the small scale factors such as industrial and agricultural production. In Hetao plain, the spatial characteristics of heavy metal element contents show that the northern and southern area are relatively high, and northern area exceeds the southern area, the change from the western to eastern area is not obvious, this phenomenon is closely related to human activities such as local industrial mining, urbanization development, industrial and agricultural production and so on.
