保定市臭氧污染时空变化特征分析研究

Time and Space Characteristics of Ozone Pollution in Baoding

为了解保定臭氧污染状况,利用2013年各环境空气自动监测点位监测数据,对臭氧污染状况及其时空变化特征进行分析。研究结果表明:1臭氧浓度的日变化呈单峰型结构,最高值与最低值分别出现在14点和6点,臭氧呈现明显的"周末效应"。2臭氧浓度的月和季度变化具有典型的季节特征,春、夏季高,秋、冬季低,与太阳辐射强度呈正相关性。3各监测点位的臭氧浓度值差异明显,最高值与最低值分别出现在游泳馆点位和华电二校点位。

In order to understand the status of Baoding ozone pollution, the time and space characteristics analysis has been performed by using 2013 ambient air monitoring data from each automatic monitoring sites. The study results showing:1)the diur-nal variation of ozone concentration exhibited a single peak profile, ie. the highest and lowest value appeared at 14:00 and 6:00 respectively, ozone concentration showed obvious weeked effect. 2)Ozone concentration of monthly and quarterly changes as the typical seasonal feature, i. e. spring and summer high while autumn and winter low. There was a positive correlation to the inten-sity of solar radiation. 3)The monitoring points the ozone density difference was obvious, the highest and lowest values were ob-served at the City Swimming Pool and Hua Dian respectively.
