Based on the data obtained by multi-purpose regional geochemical survey, the authors studied the spatial distribution of Hg in soils of Hebei plain, and drew the geochemical diagram of topsoil and deep soil. The result shows that the mean content of Hg in topsoil is 43.77×10-9, and that in deep soil is 17.58×10-9. The main chemical speciation of Hg in root soil is inert mercury, and the proportion of active mercury is only 3.24%. These data suggest that the degree of soil environmental safety is high. The Hg content in topsoil is higher in the west part of Hebei plain than in the east part. There is a significantly high value area distributed along the Taihang Mountain, which is formed by natural factors. The distribution of Hg low value area is similar to the distribution of rivers. Punctuated high value areas surrounding cities and towns are formed by human activities.
