摘要: 针对河流灌区农用地土壤重金属污染问题,采用野外调查和室内分析相结合的方法,对承德市柳河流域农田土壤中重金属进行调查,研究了柳河流域农田土壤中重金属含量特征,并使用单因子指数法和内梅罗综合指数法对土壤重金属进行了污染评价。结果表明,该地区农田土壤中重金属均未超过中国食用农产品产地土壤环境质量评价标准,但该地区农田土壤中Cd、Zn、Ni存在不同程度积累现象,应予以重视。总体来说,该地区农田土壤未受到土壤重金属污染,属于清洁水平,原种植模式可继续使用。

Abstract: Aiming at the pollution of heavy metal pollution in soil, heavy metals of Liuhe River surrounding farmland in Chengde city was surveyed using the combination of field investigation and indoor analysis. The characteristics of heavy metals content in soil of farmland were studied and pollution assessment was carried out by single factor index method and Nemerow index. The results showed that, the heavy metals contents were not exceeded the limit of Chinese farmland environmental quality evaluation standards for edible agricultural products, but the contents of Cd, Zn and Ni were accumulated in different degrees in soil. The soil of this area was not polluted, and the original planting mode, planting method and irrigation method could be continued.

Key words: Liuhe River, farmland soil, heavy metals, survey, Chengde city
