摘    要:对山西运城职业技术学院有机试验区耕层土壤(0~20cm)和灌溉水质重金属现状进行了含量分析和污染指数评价。结果表明:土壤重金属Cr、Pb、Zn、Cu、Ni含量均符合土壤环境质量标准,综合污染指数P综=0.55,评价为安全,达到国家土壤环境质量一级标准,土壤pH、有机质及各重金属之间的相关系数Cr、Cu与pH分别呈显著、极显著相关,Pb、Zn与有机质均呈极显著相关;地下水、渠水、库水的水质重金属Cr、Zn、Cu单项污染指数≤0.5,处于清洁水平,而综合污染指数P综=0.60,为尚清洁,Pb单项污染指数相对较高,灌溉用水时应引起重视。

关 键 词:土壤  重金属  有机试验区  评价

Abstract:The top soil(0~20cm)and irrigating water of an organic experiment area in Shanxi Yuncheng Vocational Technical College,in which the heavy metals were analyzed and evaluated.The results showed that :the content of Cr,Pb,Zn,Cu,Ni products be up to environmental quality standard for soils,the combined pollution index is equal to 0.55,evaluation for safety,reaching first class standard of the national environmental quality standard.In the groundwater,canal water,reservoir water,the single pollution index of Cr,Zn,Cu were all less than 0.5,on clean level,while the combined pollution index is equal to 0.60,on still clean leve,relatively higher the single pollution index of Pb,it should be pay attion to when irrigation bg water.
Keywords:Soil  Heavy metals  Organic experiment  Evaluation
