摘　　要：为研究内河溢油污染溯源问题,从溢油污染应急处置时间尺度出发,以三峡库区典型河段为例,采用拉格朗日油粒子模型,基于Fortran语言从底层开发了溢油扩展漂移及逆时追踪数学模型,模拟了三峡水库典型运行工况下的可能溢油污染过程,对溢油扩展漂移和溢油逆时追踪进行了模拟分析。结果表明该模型可较好地模拟溢油污染的扩展漂移过程及追踪寻求出污染源的大致位置,可为内河航道中不明溢油源污染事故的应急调查提供参考。To investigate the traceability of oil spills in inland rivers,we developed a mathematical model for the spread and drift of oil spill and inverse time tracking based on Fortran by utilizing the oil particle model in Lagrange theory.By using this model,we simulated the possible oil spill pollution process in the Three Gorges Reservoir during typical operation.Results indicate that the model could well simulate the spread and drift of oil spill and track the approximate location of the pollution source,thereby offering reference for the emergency investigation of unknown oil spill source pollution accidents in inland waterways.
