城市不同功能区对空气负离子水平的影响

Effect of Structure of Urban Green Space on Aero-anion Concentration

本项研究在吉林市选择具有代表性的城市功能区,对其空气正负离子浓度进行了测定,结果表明:不同功能区空气负离子水平差异显著,城市绿地中空气负离子明显高于其它非绿地功能区。

To study the effect on aero-anion concentration at different function areas of a city, the concentrations of aero-cation and aero-anion were measured on typical urban function areas selected in Jilin City. Analysis of Variance was conducted on the data obtained from measurements, intending to find the influence of different function areas on aero-anion concentration. The results are as follows: there were significant differences of aero-cation and aero-anion concentrations among different function areas of the city, and the aero-anion concentration was significantly higher at green land than in other function areas.
