Abstract: The authors take the surface soils(0~20 cm) of WuChang district as the research object. The accumulation characteristics of eight kinds of heavy metals in three types of different functional areas of surface soil were studied by means of area sampling and laboratory detection. And the soil pollution status and sources were analyzed and evaluated through the pollution index method and factor analysis method. The result shows that the surface soil of Wuchang district totally kept in clean condition,only the content of Hg stayed at the alert level. Cu,As,Cd and Hg mainly came from traf-fic area and industrial area;Cr,Ni,Zn mainly came from the industrial and agricultural areas,and the content of Pb was at a high accumulation level in the industrial area.
