| 摘 要： | 本文采用田间调查的方法研究了长期污灌对土镍形态的影响，探讨了用土壤镍形态作为指标评价土壤镍污染的可能性。结果表明，污灌带入到土壤中的镍聚集在土壤耕层，未向下迁移转化，污灌能明显增加耕层土壤碳酸盐结合态，铁锰氧化物结合态和有机质结合态镍的量，对残渣态镍没有影响。

| Abstract: | Field investigation was carried out to study the effect of long-term sew-age irrigation on formation of nickel in manured loessial soil. The possibili- ty of soil nickel pollution,which was evaluated by the soil nickel fraction, was also discussed.The results showed that the nickel coming from sewage irrigaton was concentrated in tilling hoirizon(0-20cm)of the soil, and did not migrated to the lower horizon.The content of the nickel bound to car-bonates,Fe-Mn oxides or organic matter formation in the tilling horizon was significantly increased by sewage irrigation,but the residual nickelformation remained unaffected. |
