摘要:
本文选取了云南省内五个城市的环境空气自动监测站2015年和2016年的监测数据,研究了高原城市臭氧浓度的污染特征及变化规律,分析了臭氧浓度与氮氧化物浓度及温湿度、风速这些气象条件的其相关性。结果表明,在臭氧浓度春季较高,且臭氧浓度变化与氮氧化物浓度及温度、湿度、风速这些气象条件有较好的相关性。结合云南省主要的污染物排放情况和玉溪市大气污染物源解析的结果,尝试分析了云南省臭氧污染形成的原因,并提出了控制臭氧污染的一些建议。
Abstract: By selecting data from automatic air monitoring stations located in 5 cities of Yunan Province, this paper has studied characteristics and patterns of change of pollution of ozone concentration, and analyzed the correlation among such climatic conditions as ozone concentration, nitrogen oxides concentration, temperature, humidity and wind velocity. The outcome shows that spring time sees high ozone concentration and ozone concentration correlates closely with nitrogen oxides con-centration, temperature, humidity and wind velocity. By examining major pollutant emission and sources of atmosphere pollutant in Yuxi City, the paper attempts to detect causality of ozone pol-lution in Yunnan Province and offer several suggestions addressing the issue.
