摘　　要：对奉贤区乡镇耕地环境质量现状进行了调查分析,结果表明:奉贤区94%以上乡镇耕地环境质量达到1级和2级标准,总体良好,但个别区域耕地土壤重金属镉超标,少数地区农田灌溉水砷超标,灌溉水质量总体趋势和土壤类同,并根据分析结果提出了污染防治对策。The present environmental quality of farmland in Fengxian District was investigated and the results showed that above 9496 of it reached the standard of grade 1 or 2 and the general quality was good. But the heavy metal Cd content of soil exceeded the set standard in some areas and the As content exceeded the set standard in farmland irrigation water of a few areas. The trends of both irrigation water and soil qualities were generally similar. Three countermeasures of controlling pollution were put forward based on the above analytical results.
