臭氧污染特征及影响因素研究

Study on Characteristics and Influencing Factors of Ozone in Yantai

利用烟台市国控站点环境空气质量监测数据和同期气象资料,对烟台市2015年-2019年臭氧污染情况进行统计分析,获得烟台市臭氧污染的时空分布特征,并对影响臭氧污染的因素进行探究。烟台市臭氧污染总体呈现出夏高冬低的特征,呈现倒“U”型分布特征。从空间分布来看,烟台市臭氧污染呈现出西高东低的特点。从臭氧的影响因素来看,高温低湿条件有利于臭氧的生成。本研究可为烟台市空气质量提升改善、提高臭氧预报预警能力及相关部门科学治理臭氧提供重要的数据支撑和理论依据。

Based on the ambient air quality monitoring data of national control stations in Yantai and meteorological data of the same period,the ozone pollution situation in Yantai from 2015 to 2019 was statistically analyzed.The spatial and temporal distribution characteristics of ozone pollution in Yantai were obtained,and the factors affecting ozone pollution were explored.The ozone pollution in Yantai is generally high in summer and low in winter,presenting an inverted“U”type distribution.In terms of spatial distribution,the ozone pollution in Yantai presents a characteristic of high in the west and low in the east.High temperature and low humidity are favorable to the formation of ozone.This study can provide important data support and theoretical basis for improving the air quality of Yantai city,improving the ability of ozone forecast and early warning and scientific ozone control by relevant departments.
