为研究火电企业的减排的效果并用数值形式显示火电企业排放对周围环境的影响，利用大气扩散模式ADMS-Urban进行污染物数值模拟和地理信息系统ArcGIS插值渲染方法，选取佛山市禅城区内典型的火电企业福能电厂作为研究对象，评估其减排效果。在不利于污染物扩散的气象条件下，对电厂排放的污染物进行数值模拟，并对该电厂的减排空间做情景分析。结果表明，福能电厂减排效果明显，且该电厂仍有减排空间。提高电厂烟囱高度、增大烟囱直径以及提高电厂燃料中清洁燃料的比重均可以降低电厂排放污染物对周围居民生活环境的影响，提高清洁燃料比重的可行性强。

To investigate the air quality in Chancheng area, Foshan City, the monitoring data were analyzed, which shows that after the emission control of industrial pollution, the air quality is improved. The pollutants from thermal power enterprises are reduced, but still with a high emission proportion in Chancheng area. To study the emission reduction of thermal power enterprises and to show the impact of pollutants on the environment, ADMS-Urban and ArcGIS are used to simulate the dispersal of pollutants from thermal power enterprises and the effect of emission reduction is evaluated under some unfavorable weather conditions. The further room for pollutant reduction is discussed. It is shown that pollutants of Funeng Power Plant are reduced, but with quite a room for further reduction. The increases of the power plant stack height, the diameter of the chimney and the proportion of clean fuels in power plant fuels are just a few of possible measures. The great potential exists in improving the fuel quality.
