主要城市群环境空气中臭氧浓度的变化规律解析

Analysis of the Change Law of Ozone Concentration in the Air of Major Urban Agglomerations

近年来,我国城市大气污染问题日益突出。本文主要分析了我国苏州市环境空气中臭氧浓度的变化规律,臭氧浓度的时空分布及其季节性变化特点。研究发现该城市臭氧浓度具有明显的季节性特征,春季和夏季最强,秋季其次。臭氧含量日变化呈现出一种“单峰”式的趋势,即白天为高,晚上为低。在周末的臭氧浓度比平时要高。以此为基础针对降低臭氧浓度提出有效的措施,提高整体环境质量。

In recent years,the problem of urban air pollution in China has become increasingly prominent.This article mainly analyzes the variation pattern of ozone concentration in the ambient air of Suzhou City,China,as well as the spatiotemporal distribution and seasonal variation characteristics of ozone concentration.The study found that the ozone concentration in the city has obvious seasonal characteristics,with the strongest in spring and summer,followed by autumn.The daily variation of ozone content shows a“single peak”trend,which is high during the day and low at night.On weekends,the ozone concentration is higher than usual.Based on this,effective measures are proposed to reduce ozone concentration and improve overall environmental quality.
