Soil samples were collected to determine the pollution status, spatial distribution and mobility of Vanadium (V) in soil around an iron smelter in Panzhihua. The results showed that the topsoils and deep soils were unpolluted to moderately polluted and the subsurface soils was unpolluted with V. V concentrations in the topsoils decreased with the increase of the altitudes and the distances to the smelter. There was a great potential mobility of V in soil and the reductive dissolution of reducible V in the topsoils was responsible for the high concentration of V in the deep soils. Therefore, more attention should be paid to the reducible V when evaluating the mobility of V in soil.

收集土壤样品，以确定攀枝花炼铁厂周围土壤中钒的污染状况，空间分布和迁移率。结果表明，表层土壤和深层土壤未被污染至中度污染，地下土壤未被V污染。表层土壤中的V浓度随海拔高度和距冶炼厂距离的增加而降低。V在土壤中的迁移潜力很大，而表层土壤中可还原V的还原溶解是深层土壤中V含量高的原因。因此，在评估土壤中V的迁移率时应更加注意还原性V。
