Abstract: Geochemical distribution of 14 elements in soils of Liaohe River plain and factors affecting their distribution are investigated with correspondence analysis method. The results show that these elements could be classified into three groups: oxyphilic, sulphilic and leached elements. The mentioned distribution differentiations are caused by the geochemical properties of these elements. Soil type, parent material, soil physical composition and organic matter content are the factors influencing element distribution. Clay particles with size of more than0.01mm only influences leached element distribution. Clay particles of 0.01—0.001mm and organic matter are significantly related with sulphilic and oxyphilic elements respectively.
