以黔江区城区大气中 O3质量浓度观测资料为基础，研究其浓度变化特征及相关气象因子的影响。结果表明：全年观测期间下坝 O3小时浓度未出现超标，区政府观测站点共有25d 出现 O3日最大质量浓度超标情况，最大 O3质量浓度达到262.1μg／m3。下坝和区政府观测站点年均 O3质量浓度分别为52.5μg／m3和78.1μg／m3。两个观测站点 O3小时浓度在四季均呈明显的单峰分布。气温和风速是影响黔江区大气 O3质量浓度的重要因素。
以黔江區城區大氣中 O3質量濃度觀測資料為基礎，研究其濃度變化特徵及相關氣象因子的影響。結果錶明：全年觀測期間下壩 O3小時濃度未齣現超標，區政府觀測站點共有25d 齣現 O3日最大質量濃度超標情況，最大 O3質量濃度達到262.1μg／m3。下壩和區政府觀測站點年均 O3質量濃度分彆為52.5μg／m3和78.1μg／m3。兩箇觀測站點 O3小時濃度在四季均呈明顯的單峰分佈。氣溫和風速是影響黔江區大氣 O3質量濃度的重要因素。

Based on the observed data of ozone concentration and meteorological factor in Qianjiang District,the variation characteristics of ozone concentrations and the effects of meteorological factors were analyzed.The results showed that the hourly concentration of ozone did not exceed the national standard during all the year round inXia-bamonitoring site.The daily maximum concentrations of ozone exceeded the standard twenty -five days in the whole year in Quzhengfu monitoring site.The observed maximum concentration of ozone was 262.1μg/m3 .The annual average concentrations of ozone were 52.5μg/m3 and 78.1μg/m3 in Xiaba and Quzhengfu respectively.The hourly concentrations of ozone in two monitoring sites showed obvious unimodal distribution in four Seasons.Temperature and wind speed demonstrated significant impacts on ozone.
