- Abstract:
-
A study on spatial variability of soil mercury helps to solve mercury pollution and other major ecological and environmental problems. Taking surface and deep soil of Zhaoyuan County as the research object, 258 deep soil samples and 1 030 surface soil samples were analyzed and accumulation, characteristics of element mercury in the research area were discussed by using the statistical index, semi-variogram function model of GS+software and Kriging interpolation of ArcGIS software. The results showed that there was a certain spatial correlation between samples taken from different points. element mercury distribution of the overall soil can be fully reflected, by Kriging interpolation. Element mercury of surface soil distributes more uneven, which was mainly affected by man-made factors, closely associated with irrigation, fertilizers, industrial and agricultural activities. Distribution of elemental mercury in the deep soil was mainly affected by the natural factors.
