摘    要:分析2006—2016年上海市的监测数据发现,臭氧(O_3)浓度存在逐年上升趋势,污染持续时间有所增加,但除水平风速有下降趋势外,其他相关气象因素的年际变化趋势并不显著。空间分析结果表明,上海市O_3超标主要集中在西南部郊区,但市区O_3超标潜势不容忽视。O_3污染高发季节的污染玫瑰图分析发现,上海市南部地区是影响上海市O_3污染的关键区域;对于NO_2减排的影响分析发现,尽管上海市O_3平均浓度总体处于上升趋势,但在NO_2下降幅度最为明显的内环市区和北部郊区,O_3上升幅度低于NO_2下降幅度较小的内外环区域和西部郊区,表明上海市的O_3污染控制仍需持续推进NOx的减排,并同步推进VOCs的减排。

关 键 词:上海  臭氧  时空分布特点

Abstract:The monitoring data in Shanghai during 2006-2016 demonstrated that the ozone concentration was increasing annually,however, the interannual changing trend of the relevant meteorological factors is not significant except horizontal wind speed. The diurnal variation of O3-1 h indicated that the duration of O3 pollution has been increased. The spatial analysis of ozone pollution found that the ozone exceedance in the southwest suburbs is more prominent than other areas, while the ozone exceedance potential cannot be ignored in the downtown of Shanghai.Ozone pollution wind roses of multiple sites demonstrated that the southern part of Shanghai is the key area that affects the ozone pollution in Shanghai. The analysis of the impact of NO2 emission reduction showed that although the annual concentration of O3 at Shanghai is increasing, however, the inner ring area and north suburbs, where the NO2 emission reduction are the most obvious, the rising rate of ozone is much lower than the area between inner and outer ring and western suburbs. Therefore, the ozone pollution control in Shanghai should stick to the reduction NOx, and simultaneously promote the reduction of VOCs.
Keywords:Shanghai  O3 pollution  temporal-spatial characteristics
