| 摘 要： | 对国内外文献报道的两种适合烟幕点源的大气扩散模式——高斯模式与随机游动模式进行了比较和总结，在模式推导原理和实际应用两方面分析了两种模式的优点和局限性．提出在稳定的大气条件下可选用成熟的高斯扩散模式：当大气条件较复杂，且参数选取已有可靠的经验值时应选择随机游动扩散模式。

| Abstract: | Referred to environmental assessment standard and guide, two kinds of smoke atmospheric dispersion models are compared and summarized in theory and practice. Then the advantage and limitation of the models are given. The results can provide materials for establishing smoke atmospheric environmental assessment standard and smoke agent studying. The selection of atmospheric environmental model is dependent on concrete conditions. The Gauss model can be applied in the stable atmospheric conditions, and the random walk model can be used when the parameters are reliable. |
