摘　　要：源强确定在突发污染事故的预警与应急过程中极为重要。本文针对树状河流的特性,将污染源搜索和源强反算的方法结合起来构建了树状河流突发污染事故源强确定的一般方法,并利于假设的突发污染事故情形对方法就行了评估。结果表明,监测数据的误差对计算结果的影响很大,源强的计算结果相比事故的地点与发生时间更为敏感。It is important to determine the source ＂,after a sudden pollution accident. This paper builds a general method of deter- mining the source of a sudden pollution accident occurred along a tree-structure river by combining source search and source strength calculation, and assesses the method with hypothetical pollution accident situations. The results suggest that monitoring data errors have a huge impact on final calculation, and the source strength is more sensible compared to the location of the source and the time the accident occurred.
