摘要

利用贵阳市10个环境空气监测站发布的臭氧(O₃)及其前体物NO

和CO数据，结合同期的气象观测资料，研究2015年3月1日至2016年2月29日一个自然年O₃的时空分布特征、气象作用及其与前体物的关系。结果显示O

日变化显示出“单峰”型分布特征，一般在16：00~17：00点左右达到峰值。在3~10月与次年2月，O

月平均浓度整体较高，而11月、12月和次年1月，O

浓度整体偏低。O

-8h-max浓度与日照时数、日最高气温和风速呈正相关关系，与气压和相对湿度呈反相关关系；贵阳市O

浓度城区相对较低，郊区相对较高，从市中心到郊区污染逐渐增大。大气氧化剂O

的日变化特征呈“单峰”型分布，在春季和夏季的氧化性最强。O

在白天和夜晚的控制因素不同，O

在白天主要受O

控制，在夜间主要受NO

控制。

Abstract

Based on the continuous monitoring data of O

and its precursors NO

and CO from 10 air monitoring stations and meteorological observation data in the urban area of Guiyang during a natural year from March 1st

2015 to February 29th

2016

temporal and spatial distribution characteristics of O

meteorological effects and the relationship with its precursors were studied in Guiyang city. The results showed that the diurnal variation of O

showed a "single peak" distribution characteristic

which generally reaching its peak around 16：00 - 17：00. From March to October and in February of the next year

the monthly average O

concentration was relatively high

while in November

December and January of the next year

the O

concentration was relatively low. O

-8h-max concentration was positively correlated with sunshine hours

daily maximum temperature and wind speed

and negatively correlated with air pressure and average relative humidity. The O

concentration was relatively low in the urban area and relatively high in the suburbs

and the pollution gradually increased from the downtown to the suburbs. The diurnal variation of atmospheric oxidizer O

was characterized by "single peak" distribution

with the strongest oxidization in spring and summer. O

was controlled by different factors during the day and night. O

was mainly controlled by O

during the day and NO

during the night

respectively.
