摘　　要：以重庆市涪陵区为例,以二氧化硫、可吸入颗粒物作为代表性污染物,应用PHOE NICS软件,对集中供热和分散供热锅炉房排放污染物对空气质量的影响进行了比较。污染物的分布主要受城市主导风向的影响,对于主城区,采用集中供热和分散供热时的污染物质量浓度分别是污染源的1%和5%,集中供热产生的污染面积约为分散供热的20%。Taking the Fuling district of Chongqing city for example, PHOENICS software is used to compare the impact of the representative pollutants such as sulfur dioxide and inhaled particles emitted from boiler plants for centralized and decentralized heat-supply on air quality. The distribution of the pollutants is mainly influenced by urban prevailing wind direction. In the principal urban area, the mass concentration of the pollutants is 1% and 5% of pollution source respectively when using centralized and decentralized heat-supply, and the contaminated area by centralized heat-supply is about 20% of that by decentralized heat-supply.
