摘要
对北京市城近郊区大气环境中二氧化硫(SO2)、氮气化物(NOx)、总悬浮颗粒物(TSP)和一氧化碳(CO)4种主要污染物的平均浓度随时间变化趋势作了分析,并利用模糊综合评判模型对各年大气环境质量状况进行了综合评价,最后指出了改善北京市大气环境质量的必要性。
The variable trends of the average densities of 4 main air pollutants in Beijing urbanization, SO2, NOX, CO and TSP, were analyzed with time. And the fuzzy comprehensive evaluation was applied to assess comprehensive air quality of Beijing from 1996 to 2003.
