| 摘 要： | 利用长期定位观测方法对大夫山森林公园的大气质量进行监测,分析了大夫山森林公园大气污染源的种类、数量、分布规律,包括NO、NO2、NOx和SO2浓度的日变化规律、季节变化规律进行了探讨。在此基础上,通过分析森林公园大气污染物超标率和分担率情况来评价大夫山森林公园大气质量的影响。结果表明,大夫山森林公园的大气质量非常良好,SO2和NOx秋冬季对大气环境有轻微污染,污染分担率最大的SO2,其次是NOx,而NO和NO2对大夫山森林公园环境不产生影响。为进一步提高森林公园的大气环境质量,建议增加冬季常绿阔叶树种。

| Abstract: | The air quality was monitored by long-term instruments （Thermo Fisher Scientific 42i ＆43i） in Dafushan forest park, this paper analyzed the types , quantity, distribution of the air pollutants in the Dafushan Forest Park, discussed the daily variation and seasonal variation of the concentrations of NO, NO2, NOx and SO2 in the park. After that, the air quality of the park was evaluated by the pollutant concentration exceeded the standard concentration and the proportion of each pollutant. The results showed that the air quality of the dafushan forest park is superior. The SO2 and NOx have only small effects on the air quality in winter and autumn. And SO2 was the main factor of the pollution, second is NOx, but NO and NO2 doesn＇t work. To lower down the air pollution of the park, it is a must to plant more evergreen broad-leaved tree. |
