摘要
为探讨高原山地城市臭氧污染特征,基于云南省国家环境空气自动监测站点臭氧及相关污染物、气象监测数据,该文分析了臭氧时空变化特征及其与其他环境因子的相关性。结果表明,2019年臭氧污染集中在滇中区域的曲靖、玉溪以及滇西南区域的普洱等城市;臭氧浓度月变化呈现"双峰型",日变化呈现"单峰型"特征,不同区域存在不同程度的"周末效应";臭氧与湿度、温度的相关性较好,温度25~35℃,湿度20%~40%,风速0~5 m/s及西南风向容易出现臭氧超标。
In order to explore the characteristics of ozone pollution in plateau mountainous cities,based on the data of ozone and related pollutants and meteorological monitoring at Yunnan national ambient air monitoring station,the temporal and spatial variation characteristics of ozone and its correlation with other environmental factors were analyzed.The results showed that ozone pollution was concentrated in Qujing,Yuxi and Pu’er cities in central Yunnan in 2019.The monthly variation of ozone concentration presented"bimodal type",and the diurnal variation showed"single peak type",and different"weekend effect"existed in different regions.The correlation between ozone and humidity and temperature was good,with temperature 25~35℃,humidity 20%~40%,wind speed 0~5 m/s and wind direction.It is easy to exceed the standard of ozone in the southwest.
