摘　　要：针对缺资料地区水体突发性重金属污染事件,开展快速预警研究,可以快速预测重金属到达下游水域敏感点的时间和影响程度及范围,以降低突发事件带来的危害。通过地形概化、水力学特征参数快速设置、特征污染物参数选取、模型参数自动校正,建立了缺资料地区水体突发重金属污染事件的快速预警方法,并应用于甘肃突发锑污染事件。将预测值与实测值进行相关性分析,R^2在95%以上,表明该方法可对甘肃锑污染事件发生后污染物到达下游敏感点的时间、浓度变化过程与影响范围进行很好的预测,为事故的风险预警及应急决策提供了依据。The study on rapid alert for abrupt water heavy metal pollution in ungauged basins can simulate and predict the transport process, spatial and temporal distribution of heavy metals, which is helpful for water environmental emergency risk dis- posal. By generalizing digital terrain data, quickly setting up hydraulics characteristic parameters, choosing representative pollu- tant values and automatically correcting model parameters, a rapid alert method for abrupt water heavy metal pollution in un- gauged basins was developed and applied to simulate the antimony pollution accident in Gansu Province, China. The correlation analysis of model predicting results and the observed data showed that the R2 is over 95%, proving that the method could success- fully predict the antimony transport process. The＇results provided basis for risk pre -warning and emergency decision for the acci- dent.
