为探索大冶矿区主要公路交通干线两侧农田土壤中重金属的污染现状,为矿区公路两侧农业土壤的安全利用及污染的防治提供一定的科学依据,利用单因子污染指数及内梅罗综合污染指数法评价其环境质量状况,并进一步分析污染的主要来源。结果表明:通过单因子及综合污染指数评价发现,矿区主要公路两侧的农田土壤已受到不同程度的污染,可能对农产品生产造成一定程度的潜在安全隐患。土壤有机质与Cu、Cd、Cr及 Ni元素的相关系数均较低。主成分分析显示,大冶矿区公路两侧农田土壤重金属的来源可能为金属冶炼、制造业和交通释放的气溶胶颗粒,以及矿山酸性废水、金属矿山废石和尾矿的长期储存等人类活动。
為探索大冶礦區主要公路交通榦線兩側農田土壤中重金屬的汙染現狀,為礦區公路兩側農業土壤的安全利用及汙染的防治提供一定的科學依據,利用單因子汙染指數及內梅囉綜閤汙染指數法評價其環境質量狀況,併進一步分析汙染的主要來源。結果錶明:通過單因子及綜閤汙染指數評價髮現,礦區主要公路兩側的農田土壤已受到不同程度的汙染,可能對農產品生產造成一定程度的潛在安全隱患。土壤有機質與Cu、Cd、Cr及 Ni元素的相關繫數均較低。主成分分析顯示,大冶礦區公路兩側農田土壤重金屬的來源可能為金屬冶煉、製造業和交通釋放的氣溶膠顆粒,以及礦山痠性廢水、金屬礦山廢石和尾礦的長期儲存等人類活動。

The characteristics of heavy metal pollution in farmland soils on both sides of the main roads in Daye mining area were studied to provide scientific evidence for safe utilization and the pollution prevention of the agriculture soil in the mining area .Its environmental condition was evaluated by using Single Factor Index Method and Nemerow Integrative Pollution Index Method and the major source of pollution was analyzed .The results showed that many farmland soils along the main roads of Daye mining area were suffering from heavy metals pollution by using Single Factor and Integrative Index Methods ,which probably resulted in the poten-tial danger for the safe production of agricultural products .The correlation coefficients between soil organic matter and heavy metal( Cu、Cd、Cr or Ni) contents were lower.The results from principal component analysis indicated that the heavy mental source of the farmland on both sides of main roads in Daye mining area is likely to be the aerosol particles emitted by metal smelting ,manufacturing and traffic ,acid mine drainage and metal mine waste rock and long -term stockpiling of tailings ,etc.
