摘要
通过野外采样和实验室分析化验相结合的方法,分析了阳高县不同利用年限设施栽培土壤中汞、铅、锌、镍、钴含量的变化规律。结果表明,设施栽培土壤在利用4～7年时重金属元素含量最高。进一步依据温室蔬菜产地环境质量评价标准,采用单项污染指数法和尼梅罗综合污染指数法,对当地设施栽培土壤金属元素含量进行了污染评价。结果表明,阳高县设施栽培土壤未受到汞、铅、锌、镍污染,尚处于清洁状态。
Contents of Hg、 Pb、 Zn、 Ni、 Co were measured in protected cultivation soil with different planting years in Yanggao County.The results showed that the maximum values of heavy metal contents of protected cultivation soils occurred when greenhouses were cultivated for 4 to 7 years.The environmental quality of protected cultivation soils was assessed by applying the single pollutant index method and the Nemerow comprehensive index method based on the environmental quality evaluation standards of farmland for greenhouse vegetables production.The results indicated that the pollutant index of Hg、 Pb、 Zn and Ni didn＇t exceed the limit value,the soil was clear.
