Description :
Contents of 13 trace elements in soils from 36 locations in Tianjin plain area were determined. The spatial autocorrelation, the directional characteristics of autocorrelation, the relationship between autocorrelation in different directions and lag of sampling were investigated. The most significant autocorrelation was found in horizon A where the original distribution patterns of the elements have been modified by natural forces and human activities.
