摘要:

研究了沈阳市城乡结合部土壤中铅的空间分布特征。结果表明,沈阳市城乡结合部耕作层土壤铅含量范围值为 72.0 63- 381.5 0 2mg/kg,已经普遍受到较严重的铅污染。铅大部分存在于表层土壤,由于深翻土地,耕地 1m深以内的土层均受到较为严重的铅污染。不同作物类型的土壤铅含量不同,污染顺序为菜地 >水稻田 >玉米田 >葡萄园。

关键词: 土壤铅, 城乡结合部, 分布特征, 沈阳市

Abstract:

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
