摘要：对扬州市不同绿地类型中空气负离子水平研究表明：城郊林和公园绿地空气负离子浓度是城区其它类型绿地的2倍,城区绿地中空气负离子水平又表现为公园〉校园〉广场〉小区〉街心游园。绿地中空气负离子浓度和空气清洁度值大部分为对照空旷地的1~3倍,广场绿地和城郊雪松林中空气清洁度达到对照区的3~4倍,且林内比林缘空气负离子浓度有显著提高。不同植被组成的绿地中空气负离子水平为高大乔木最优,灌草次之,空旷地最差。
Study on aero-anion concentration at different type of urban green spaces in Yangzhou, Jiangsu province, demonstrated that the aero-anion concentration at suburban forest and urban park were 2 times higher than that at other urban green spaces. The aero-anion concentration sequence at different green spaces was as follows： park 〉 campus 〉 square 〉 residential district 〉 center garden of the street. The aero-anion concentration as well as CI value at abovementioned zones was about 1 - 3 times in comparison with non-greening zone （ck）. The CI value at square and suburban forest （Cedrus deodara） even researched 3 - 4 times of ck, and aero-anion concentration was significantly higher than than at forest edge. The result also showed that aero-anion concentration at different types of vegetation was as follows： tall trees〉shrub and grass 〉open space.
