摘要
为研究沈阳市大气降尘与土壤磁化率的关系,对2006年冬季和2007年春、秋两季沈阳市区大气降尘的磁化率进行测定,并与城市表层土壤和郊区耕地土壤进行比较。结果表明:沈阳市内五区之间降尘和土壤磁化率均有差异;市区大气降尘显著高于城市表层土壤,而城市表层土壤又明显高于郊区耕地土壤,说明城市大气降尘受工业和生活污染较为严重,而城市土壤又受到降尘的污染。
From the winter of 2006 to the spring and autumn of 2007, we determined the magnetic susceptibility of atmospheric dust in the urban area of Shenyang city,and compared with urban surface soil and suburban cultivated soil. The results showed that： Between the five areas of Shenyang city, dust and soil magnetic susceptibility are different; in urban atmospheric dust it is significantly higher than that in urban surface soil, and in urban surface soil it is significantly higher than that in suburban farmland soil, which shows that urban air dust by industrial and domestic pollution is more serious, and the urban soil is polluted by the dust has received.
