摘    要:本研究通过对蒲城县农业土壤重金属含量进行研究分析,选取0~20 cm土层深度的表层土采点37 个,对比分析了土壤中Mn、Sr、Pb、Zr、Zn等5 种重金属含量及累积情况,并采用了单因子污染指数法等多种方法进行了土壤重金属污染评价。结果表明:蒲城县农业土壤存在一定的Mn、Sr 累积趋势,但分区差异不是特别明显。从单因子污染指数看,蒲城县农业土壤重金属污染主要是Sr 的污染。Sr 的单因子污染指数都大于3,处于重度污染,Mn、Zn、Pb 的单因子污染指数小于1 处于清洁状态。总体来看蒲城县农业土壤重金属Sr 的含量严重超标,制约了蒲城县农业的发展,对人体也造成极大危害,应及时做出对策,Mn、Pb、Zr、Zn的含量存在超标,但并不严重处于可控制范围内。

Heavy Metal Contamination of Soil in Pucheng
Abstract:The paper analyzed agricultural soil heavy metal content in Pucheng county, studied Mn, Sr, Pb, Zr and Zn content and their accumulation in 0-20 cm soil layer of 37 sampling sites, methods such as single factor pollution index method for evaluation of soil heavy metal pollution were used. The results showed that agricultural soil in Pucheng had certain Mn and Sr accumulation, but the difference among the sampling sites was not obvious, from the single factor pollution index, agricultural soil pollution in Pucheng was mainly Sr. Single factor pollution index of Sr was greater than 3, at the level of high pollution, that of Mn, Zn and Pb was less than 1, belonged to clean condition. Overall Sr content in Pucheng agricultural soil exceeded standard seriously, and restricted the development of agriculture and harmed human health, which should be timely dealt with; from the comprehensive pollution index, Mn, Pb, Zr and Zn content exceeded the standards, but was not serious and in the controllable range.
Keywords:Pucheng county  Agricultural soil  Analysis of pollution  Pollution factors
