青岛市大气环境质量状况分析与评价

对青岛市大气主要污染物变化趋势进行了分析,并利用模糊综合评价模型对各年大气环境质量状况进行了综合评价。研究结果表明:近10年来青岛市大气环境质量处于尚清洁状况,且在不断改善;受工业扬尘和建筑扬尘影响,青岛市主要污染物是可吸入颗粒物PM10;以煤炭为主的能源结构加之落后的工艺设备等原因使得大气中二氧化硫浓度一直处于较高水平;随着青岛市机动车保有量的增长,以氮氧化物为特征的机动车尾气污染日趋明显,因此,冬季采暖燃煤利用、机动车尾气控制及城市扬尘抑制仍是青岛市未来大气污染的治理重点,强化燃煤脱硫技术和改善机动车尾气排放是青岛市大气环境质量改善的关键。

Analysis and Evaluation on the Atmospheric Environmental Quality of Qingdao

The tendency of the major matter of atmosphere pollutant in Qingdao City is analyzed.A rough comprehensive evaluation model is used to evaluate the situation of atmosphere quality in different years.The result of the research shows that the atmosphere quality in Qingdao is narrowly clear and is continuously improving in the last decade;that the major matter of atmosphere pollutant in Qingdao is inhalable particle PM10,influenced by the industrial and constructive dust;that the concentration of sulfur dioxide in atmosphere has been on a relatively high level due to the coal-dominating energy structure as well as the backward technology and equipment;with the increase of the inventory amount of motor vehicle in Qingdao,the pollutant characterized with oxynitride of vehicle emissions is increasingly apparent.Therefore,the main points of control of the atmospheric pollution in Qingdao City should be focus on the use of winter heating coal,the control of vehicle emissions,the restrain of the urban flying dust.The key points of the improvement of the atmospheric quality in Qingdao City are remained to be the reinforcement of coal desulfurization technology and the amelioration of the vehicle emissions.
