北方城市市区大气臭氧污染时空变化特征分析与协同治理策略研究

Analysis of Temporal and Spatial Variation Characteristics of Atmospheric Ozone Pollution in Urban Areas of Northern Cities and Coordinated Governance Strategies

臭氧气体会刺激人体器官粘膜,对人体呼吸系统产生影响,当臭氧浓度过高时,也会对植物和动物产生危害,因此需要提出臭氧污染的治理策略,降低城市市区的臭氧污染程度。提出北方城市市区大气臭氧污染时空变化特征分析与协同治理策略,挑选沈阳作为研究区域,首先获取了沈阳的污染浓度分布数据,采用皮尔森相关系数分析氮氧化物、PM_(10)、PM_(2.5)、一氧化碳和二氧化硫对臭氧浓度分布产生的影响,其次,分析了城市市区大气臭氧污染的季节变化特征、月浓度变化特征以及日变化特征,最后根据臭氧污染时空变化特征分析结果,提出臭氧污染的协同治理策略。

Ozone gas will stimulate the mucous membrane of human organs and have an impact on the human respiratory system.When the concentration of ozone is too high,it will also cause harm to plants and animals.Therefore,it is necessary to put forward ozone pollution control strategies to reduce the degree of ozone pollution in urban areas.This study analyzes the spacial and temporal changing characteristic of atmospheric ozone in the northern city and collaborative management strategy.Taking Shenyang as a research the area,it the first obtained the pollution concentration distribution data in Shenyang by using Pearson correlation coefficient analysis of nitrogen oxides,PM_(10),PM_(2.5),carbon monoxide and sulfur dioxide on ozone concentration distribution.Secondly,it studies urban atmospheric ozone pollution seasonal change characteristics,monthly concentration change characteristics and daily change characteristics.A collaborative governance strategy of ozone pollution is finally proposed.
