利用2004～2006年杭州主城区环境空气监测资料,研究了O_3、NO_2和CO浓度的分布特征和时间变化规律,结果表明,杭州主城区3年的O_3、NO_2、CO的年均浓度都不大,分别为40、60、1400μg·m~(-3).四季中O_3、NO_2和CO浓度相差较大,O_3是夏季高冬季低,NO_2和CO则是秋季较高,夏季较低.O_3、NO_2和CO浓度日变化也很明显,其中O_3是单峰形态,NO_2和CO为双峰形态.不同天气条件下O_3与烃类的关系研究表明,晴天时烃类浓度减少,O_3浓度明显增加;阴天时O_3浓度较低,烃类浓度较高,它们的变化不大.白天和夜晚不同风速时O_3、C_2-C_(12)的浓度变化不同,白天风速增大时C_2-C_(12)浓度减小,O_3浓度增加;晚上无此变化.

Based on the air monitoring data in Hangzhou urban areas from 2004 to 2006, the concentrations of O_3 , NO_2 , CO, and their temporal variation characteristics were analyzed.The results showed that all the annual mean concentrations of O_3 , NO_2, and CO were low in the three years, which were 40, 60, and 1400 μg · m~(-3) , respec-tively. The concentrations of O_3 , NO_2 , and CO were different among seasons, O_3 concentration was the highest in summer and the lowest in winter, while both NO_2 and CO concentrations were higher in winter and lower m summer. The diurnal variations of the concentrations of O_3 , NO_2 , and CO were obvious, the diurnal variations of O_3 concentrations showed one peak, while the others had two peaks.The relationship between O_3 and hydrocarbons concentration in different weather conditions showed that O_3 concentration increased significantly and hydrocarbons reduced during cloudless days, but during cloudy days O_3 concentration was lower and hydrocarbons concentrations were higher, and their concentrations changed little In the daytime and nighttime, O_3 and C_2-C_(12) hydrocarbons concentrations changed with different wind velocity. In the daytime, the C_2-C_(12) hydrocarbons concentrations reduced with the increase of wind speed, and O_3 was exactly opposite.The similar situation was not found in the nighttime.
