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。

摘  要：
The soils were sampled from 306414 hm2 of cultivated land and were monitored in Yangzhou area.The heavy metal elements such as cadmium,hydrargyrum,arsenic,chromium,cuprum,plumbum were analyzed according to the (NY/T391-2000),zinc,nickel,BHC and DDT were analyzed according to the standard in (GB15618-1995).The plantation soil environmental quality in Yangzhou was estimated,otherwise the dynamic change and cumulated condition of heavy metal content in soil during 20 years were analyzed.The result showed that 90.9% soil sampling points were cleaning,8.3% soil sampling points were close to cleaning,the change of heavy metal content was not remarkable,and the cumulation was not prominent.The plantation was not polluted obviously by heavy metals and organic chlorine pesticides,and soil environmental quality accord to the level of great national high grade rice produce base.
