• 摘要：伴随着经济发展和城镇化进程的加速，很多城市的臭氧浓度存在超标问题.本文选取2014—2017年哈尔滨城区污染数据及气象要素数据，对哈尔滨近地面层O₃时空分布特征及其与气象要素的关系进行了分析，结果表明：哈尔滨O₃日内单峰分布，最高值出现在下午14：00，最低值在清晨7：00.空间分布东南部最高，其次是南部，城中区较低.日间周末的近地面O₃浓度较高，而夜间工作日的O₃浓度较高.哈尔滨O₃浓度与平均气温正相关，与相对湿度负相关，与低于37 W·m^-2的紫外辐射正相关.

• Abstract：With the development of economy and rapid urbanization, ozone concentration in many cities has exceeded the official standard. In this paper, the spatial and temporal distribution of O₃ in the near-surface layer of Harbin and its relationship with meteorological elements has been analyzed using the pollution data and meteorological data of Harbin from 2014 to 2017. The research results show that, the maximum value of daytime single peak distribution of O₃ in Harbin appears at 14:00, the minimum value is around 7:00. The spatial distribution of near surface O₃ in Harbin indicates that the highest value is located in southeast Harbin, followed by the southern Harbin, and central Harbin has the lowest value.In daytime, the near surface O₃ concentration in Harbin has higher value during the weekend, and in nighttime, the higher value can be found during the weekday.The O₃ concentration in Harbin is positively correlated with the mean temperature, negatively related to relative humidity, and positively correlated with ultraviolet radiation below 37 W·m^-2.
