攀枝花地区昔格达土中钒的含量及分布

对母质为昔格达组粘土的攀枝花土壤样品数据进行了分析研究。结果表明，该区土壤中的钒普遍具有一定的地带性分布规律及剖面分布特征。一般来说，矿区土壤中的钒含量明显高于非矿区，表明该区土壤主要受采矿污染的影响；水田土壤中钒含量明显高于旱地，表明水是钒元素迁移的重要介质（载体）。钒含量在土壤剖面上的空间分布呈底层富集型，反映了成土因素的综合影响。

CONTENT OF VANADIUM AND ITS DISTRIBUTION OVER XIGEDA SOIL, PANZHIHUA REGION, SICHUAN

As a trace element distributed over the earth evenly, vanadium may do harm to the growth of plants and animals. Once accumulation of vanadium occurs, it may bring hurt to human through food chain. According to this, the authors have done some work on this element. This paper analyses the data of the samples in the Xigeda soil from Panzhihua. The result shows that there exits a certain zonal law about the distribution of vanadium. Generally speaking, the average content of vanadium in mine areas is obviously higher than that in non mine areas. This indicates that the soil in this area is influenced by the mining pollution. The average vanadium content in paddy field is higher than that in dry land. This indicates water is an important carrier during the transfer of vanadium. The distribution of vanadium over a soil profile shows it is an enriched type at the bottom.
