摘　　要：以高斯烟团模型为基础,引入坐标变换思想,建立了适用于变风场的大气污染扩散模型,并结合蒙特卡罗模拟初步构建了更为合理的安全距离确定方法,一定程度上解决了参数不确定性所导致的预测结果偏差。以大连市松木岛化工园区为例,得到不同方向上污染物的危害距离,得出相应的风险评价结论。On the basis of Gaussian puff model, coordinate transformation is combined to build the gas diffusion model which is adapted to dynamic wind conditions. By combining Monte Carlo simulation, a more reasonable safety distance de- termination method is primarily established. This method has solved the deviation of results caused by parameter uncertainty to some extent. Taking Dalian Songmu island chemical industrial park as an example, pollutants＇ hazard distance of different direction has been got, as well as the corresponding risk assessment conclusions.
