摘　　要：在云南539对土壤与农作物协同样品检测分析的基础上,采用土壤和农产品综合治理指数法对农田土壤环境质量进行评价。结果表明稻田土壤镉、砷含量均低于玉米地为代表的旱地。539个点位中清洁点位占41.4%、轻微污染点位占26.0%、轻度污染点位占13.9%、中度污染点位占8.0%、重度污染点位占10.8%。Based on the analysis of collaborative samples of soil and crops in 539 sampling sites in Yunnan province,comprehensive index combined soil environmental quality and agricultural products quality was applied to evaluate the environmental quality of farmland soil.The results showed that the content of cadmium and arsenic in paddy soil was lower than that of dry land.Among the 539 points,clean points accounted for 41.4%,slightly polluted points 26.0%,lightly polluted points 13.9%,moderately polluted points 8.0%,and heavily polluted points 10.8%.
