摘　　要：为了研究土壤中钒的沉积物污染状况以及生态危险,采集贵州省遵义市富多金属黑色页岩区森林土、旱地土、耕地土、水稻田土4种类型土壤,采用电感耦合等离子体质谱仪检测土壤中的钒含量,利用地质累积指数、内梅罗综合指数和潜在生态危害指数方法研究该区域钒元素污染及其潜在生态危害。结果表明:研究区各类土壤积累了不同含量的钒元素,森林土、旱地土、耕地土和水稻田土中钒元素的平均质量比分别为445.73、291.82、486.30、283.80 mg/kg,均远超过国家土壤环境质量标准中的要求;研究区土壤受钒的沉积物污染程度较高,存在中度潜在生态危害。To research pollution status and ecological risks caused by precipitates of vanadium in soil,four types of soils named forest soil,dryland soil,cultivated soil,and paddy soil in research areas rich in polymetallic metal black shale in Zunyi city of Guizhou province were collected.Contents of vanadium in soils were detected by using inductively coupled plasma mass spectrometer.Methods of geological accumulation index,Nemerow comprehensive index,and potential ecological hazard index were used to investigate pollution and potential ecological hazards of vanadium element in the areas.The results show that different types of soils accumulate vanadium element with different contents of in research areas.Average mass ratios of vanadium element in forest soil,dryland soil,cultivated soil,paddy soil are respectively 445.73,291.82,486.30,283.80 mg/kg,which all exceed requirements in national soil environmental quality standards far away.The soils in research areas are polluted to a higher degree and have moderate potential ecological hazard.
