The spacial distribution of lead in soil of the connection of urban and rural of Shenyang city is studied, and the results show that the range of value of the lead content in soil of the connection of urban and rural of Shenyang city is 72.063 - 381.502 mg/kg,and it has been polluted widely.Most of the lead consists in the surface of soil,because of the ploughing deeply,the soil layer depth of 1 meter was polluted seriously by lead .The lead content of soil is different between different plants,the series of pollution is vegetable land>rice land>corn land>grape land .
Key words： lead in soil; connection of urban and rural; distribution; Shenyang city
