摘要
利用2009年夏季乌鲁木齐市近地面大气O_3及其前体物的自动监测数据,分析了O_3浓度的分布特征和时间变化规律。探讨O_3与其主要前体物NO_2和CO的相关关系。结果表明,乌鲁木齐市夏季的O_3污染较轻;O_3浓度呈单峰型分布,O_3浓度昼间高,夜间低;昼间O_3与其主要前体物都呈负相关关系。
Using auto - monitoring datum of ozone and its reactant near the ground in summer 2009, the paper analyzes distribution character and time change disciplinarian for ozone concentration, discusses correlation of ozone and its main reactant （nitrogen dioxide and carbon monoxide）. The result shows ozone pollution in summer is light, ozone concentration presents single apex distribution, ozone concentration is high in day but low in night. Ozone and its main reactant is negative correlation in day.
