摘要： 为了研究潼关农田土壤重金属累积现状，通过采用单因子污染指数及综合污染指数的方法，研究当地4种土壤重金属的污染现状。结果表明：Pb的单因子污染指数为4.69，达到重度污染；Cu、Sr分别为2.23、2.77，达到中度污染；Zr为0.78，处于尚清洁水平；研究区综合污染指数为3.61，处于重度污染。当地应采取适当措施，加强对该地区污染的防治工作，避免对人体健康造成危害。

Abstract: In order to study the soil pollution assessment of heavy mental in Tongguan, sampling and analysis the content of the 4 kinds of heavy mental in surface sediments, and using the single factor pollution index and Comprehensive pollution index to evaluate it. The results showed that, Pb single factor pollution index was 4.69, pollution was serious; Sr, Cu was 2.23 and 2.77, achieve the moderate pollution; Zr was 0.78 lower levels of contamination. It was 3.61 of comprehensive pollution index, pollution was serious. Thus, appropriate measures should be adopted to strengthen the prevention and control of pollution in the region and avoid the harm to human health.
