沈阳世博园空气负离子浓度的研究

Research of the Aeroanion Concentration in Shenyang EXPO Park

对沈阳世博园空气负离子浓度进行了观测和研究,结果表明园内空气很清洁,负离子浓度约为城市居民区的2倍;空气负离子浓度日变化明显,早晨和午夜前后空气负离子浓度较高,空气最为清洁,白天午后空气负离子浓度较低;不同环境游憩区空气负离子浓度明显不同,由高到低依次是:水边>林内>林边广场>开阔草地>温室;空气负离子浓度与气温呈显著负相关关系,与空气湿度呈显著正相关关系。

This paper studied the aeroanion concentration in Shenyang EXPO Park. According to observation, conclusions were the following： The air in the park was very clean and the aeroanion concentration was twice the residential areas in urban. It was showed that the aeroanion concentration changed obviously during a day. The concentration was higher in early morning and midnight, and the ability of air was better. In mid-day, the air-anion concentration was lower. The aero-anion concentration was obvious difference in different environment of recreation. By the aero-anion concentration, the descending order was follows： waterside, forests, woodside square, spacious lawn, and greenhouse. There was obvious negative correlation between aeroanion concentration and temperature and obvious positive correlation between aeroanion concentration and humidity of air.
