Abstract: The feature of cadmium distribution in profiles of some natural soil in Beijing area were discussed in this paper. Under natural condition,the cadmium was accumulated in B layer of brunisoilc soil,However,it was not accumulated obviously in leached drab soil and typical drab soil,and it was not accumulated in ling drab soil. The content of cadmium in surface was always higher than that of the subsoil in fluvo-aguic soil.The content of cadmium was increased with soil texture grade increase in subsoil of fluvo-aquic soil. The map of cadmium distribution in soil in Beijing area was drawn. Rcgional differentiation of cadmium in natural soil was less. Little soil were pollutcd in vary degress at sewage water irrigation area.
