| 摘 要： | 对扬州市域内306413 hm 2耕地土壤进行采样监测,Cd、H g、As、Cr、Cu、Pb 6种重金属采用《绿色食品产地环境技术条件》(NY/T391-2000),Zn、Ni和666、DDT采用《土壤环境质量标准》(GB15618-1995)水田二级标准,对扬州市耕地土壤环境质量现状进行了评价,在此基础上,对扬州市土壤近20年重金属含量动态变化及累积情况进行了分析。研究结果表明,在扬州市耕地土壤中,90.9%的样点土壤处于清洁水平,8.3%的样点土壤处于尚清洁水平,近20年内土壤重金属含量变化不大,无明显累积现象,扬州市耕地土壤未受到重金属和有机氯农药的明显污染,土壤环境质量满足国家大型优质稻米生产基地的产地条件。
