农村土壤环境质量状况分析——以重庆市某村庄为例

以重庆市某村庄为研究对象,采用土壤单项污染指数法和土壤综合污染指数(内梅罗污染指数)法,对5种不同类型的15个土壤样品进行分析测定。研究结果表明,该村主要污染物为镉、镍;单项污染指数法评价表明,畜禽水产养殖场周边土壤轻度污染,其余监测点位的土壤均为轻微污染;综合污染指数法评价表明,菜地、畜禽水产养殖场周边土壤为轻度污染,其余监测点位的土壤为尚清洁。

A village of Chongqing city as the research object, using soil single pollution index method and compre-hensive pollution index(Nemerow pollution index)method to analyze five different types of 15 soil samples. The research results show that main pollutants of the village are cadmium and nickel; soil single pollution index evaluation method shows that the soil of livestock aquaculture farms around are light pollution, the other soil monitoring points are slight pollution; comprehensive pollution index evaluation method show that the soil of vegetable plots and live-stock aquaculture farms around are light pollution, the other soil monitoring points are still clean.
