中文摘要	以典型绿洲区土壤-植物系统为研究对象,在大田条件下创建了干旱区绿洲土壤氟生态风险评估模型,并运用此模型对白银市城郊土壤氟污染进行了风险评估,具体表现为用潜在生态风险氟有效态含量评估模型(ER_(bc))评估绿洲区土壤氟污染生态风险.结果表明,研究区生态风险指数介于1.37 ~24.81,绝大多数地点风险程度表现为很高到极高,平均生态风险指数为11.28,风险程度为极高.白银市东大沟水浇地农田土壤需关注氟污染的修复.
英文摘要	According to translocation regulation of fluoride in the typical oasis soil-plant system under field, an ecological risk assessment model of fluoride was established,and this model was used to assess ecological risk to fluoride pollution from suburban oasis soils in Baiyin City, which was specifically expressed with the potential ecological risk of bioavailability (ER_(bc)) model to assess ecological risk of fluoride pollution in oasis regions. Results showed that the ecological risk indices of fluoride pollution from this region were 1. 37-24. 81,the level of risk at most sites was high to very high, the average ecological risk index was 11. 28,belonged to very high risk. This indicated that in the suburb soil of Baiyin City needs to be concerned about the remediation of fluoride pollution.
