大气污染物扩散模式的应用研究综述

A review of the development and application of air pollutant dispersion models

应用大气污染物扩散模式可以模拟不同尺度、气象、地形条件下工业污染物在大气中的输送与扩散特征,为大气监测、城市环境规划和空气质量预报等工作提供科学依据。归纳了目前广泛应用于模拟工业污染物扩散的模式,着重介绍了近年来国内外对这些模式的主要应用研究进展,比较了各模式在应用上的优缺点,并对大气污染物扩散模式的应用研究前景进行了讨论。

The air pollutant dispersion models were used to simulate characteristics of transportation and diffusion of gaseous pollutants in different scales, meteorology and terrain conditions, providing scientific basis for air monitoring, urban environmental planning, and air quality prediction. A comprehensive overview of models being widely used to simulate the dispersions of industrial gaseous pollutants in and outside China during recent years was presented. The suitability of the models under different kinds of conditions was compared from the point of view of application. Finally, the foreground of dispersion models was discussed.
