【摘要】 几种大气污染扩散模式应用比较表明:CAPPS模式应用于国内一些城市空气污染预报,方法简单;NAQPM模式对物理、化学过程的处理、气象场模拟、污染源排放、地域环境特征、数据处理分析与计算均采用较为科学的方案;ISC在污染源排放清单和气象参数确定方面更加细致、准确;ADMS的主要特色是应用的多功能性,主要用于环境容量测算、环境质量评价方面以及大气污染预报等;Models-3模式对各种大气污染物浓度分布实施有效预测,进行较为全面的空气质量控制策略的评估。大气污染扩散模式的不断完善,使得空气质量控制和管理更加富有成果。更多还原

【Abstract】 The comparison between air pollution dispersion models reveals: CAPPS model is relatively a simple method in predicting urban air pollution;NAQPM offers more scientific solutions to physical and chemical process handling,meteorological field simulation,source emission,regional environment feature and data processing analysis and calculation;ISC gives a more detailed determination of emission inventory and meteorological parameters;ADMS,with multifunction,is mainly used for environmental capacity measurement,environmental quality assessment,atmospheric pollution prediction,etc.;Model-3 may realize an effective forecast of air pollution concentration distribution and comparatively comprehensive evaluation of air quality control strategies.However,the continuous improvement of air pollution dispersion models will enable us to have more achievements in air quality control and management.更多还原
