摘要: 利用2013—2015年深圳国家基本气象站的观测资料和11个国家环境监测点的O3监测资料对深圳市臭氧(O3)的污染特征及影响O3的气象条件进行了统计分析。结果表明:2013—2015年深圳市11个环境监测点均存在不同程度的O3超标现象,O3超标率为0.7%—11.9%,全市臭氧平均超标率为4.1%。深圳市O3污染呈内陆地区污染重、沿海地区污染轻的特点。深圳市秋季和冬季O3 污染较重,夏季O3 污染较轻。综合气象条件是深圳市O3污染变化的重要因子,有利于O3污染的气象条件为较高的温度、充足的日照、干燥、无雨及弱风。Abstract: Statistical analysis based on meteorological data from Shenzhen National Basic Meteorological Station and ozone data from 11 national environmental monitoring stations during 2013-2015 were carried out to investigate the pollution characteristics and meteorological conditions influencing ozone.The results show that the concentrations of ozone exceed standard in different degrees at all the environmental monitoring stations with the rate between 0.7% and 11.9%,and the average rate of 4.1% in Shenzhen.Spatial distribution of ozone pollution appears to be higher concentration in inland region and lower in the coastal region.Ozone pollution seems to be heavier in autumn and winter,whereas lighter in summer.Synthetic meteorological conditions are important factors for the pollution development of ozone,among which the relatively high temperature,sufficient sunshine,dry weather,and weak wind are most important influencing factors.
