GEOGRAPHICAL DIFFERENTIATION OF HEAVYMEDAL STATE IN SOILS (Cd,Pb AND Cu)

Luo Jinfa\ Xia Zenglu\ Meng Weiqi (Institute of Geography, Chinese Academy of Sciences, Beijing\ 100101)  
According to the study on nine types of soils, including brown soils, for subtypes of cinnamon soils and other non zonal soils, this paper discusses the existence state and the differentiation characters of heavy medal Cd, Pb and Cu. It also discusses the relationship between soil properties, such as pH and organic matter, and regional differentiation of heavy medal state. Therefore, this paper shows the law of regional differentiation of heavy medals in the soils in the south and north direction and east and west direction.
