【摘要】 选择在复杂地区应用较好的高斯轨迹烟云扩散模型，作为贵阳市空气质量预报的数学扩散模式，并利用贵阳市现有的污染源排放资料和气象资料，对贵阳市的大气污染物分布进行了模拟计算，经与实测结果比较表明：实测值与监测值基本一致，相关性较好。该模式可以作为贵阳市空气质量预报的数学扩散模式，对其他城市也具有一定的借鉴作用。更多还原

【Abstract】 Gauss plume trajectory model was selected as the model for air quality forecast in Guiyang City. Air pollutant distribution and Air Pollution Index(API) in Guiyang were calculated by the model with input of the meteorological and pollution sources data. It is shown that the simulation and monitoring values have a good interrelation. The model can be applied in air quality forecast in Guiyang and is helpful for other cities.更多还原
