摘    要:利用空气离子自动检测仪,选择2012年3月27~28日和5月2~3日一个时间段,再选择2012年4月18日上午雷雨前后一个时间段对南宁市一小区(经纬度:108°19′13″,22°49′21″)的空气负离子浓度进行测量,探讨南宁市空气负离子浓度日变化及不同天气条件下的变化,同时还测量南宁市10个不同监测点的空气负离子浓度并进行对比,探讨南宁市不同功能区的负离子浓度的差异。结果发现,南宁市空气负离子浓度的变化为夏季测量时间段高于春季测量时间段,夜晚测量时间段低,白天测量时间段高;雷雨后的测量时间段空气负离子浓度和空气质量要好于雷雨前测量时间段,两者差异显著;不同功能区测量时间段内空气负离子浓度差异显著,依次为南宁市远郊风景区>近郊风景区>城市公园>交通干线。

关 键 词:空气负氧离子日变化  功能区

Abstract:In this study,positive and negative aeroions were measured by automatic aeroions detector in some regions of Nanning from March to May,2012.Subsequently,the air qualities of corresponding region were evaluated. Results indicated that the air negative ions concentrations were higher in spring than that in summer. Furthermore,concentration of the air negative ions during daytime is higher than that at night. And after the occurrence of thunderstorm,concentration of air negative ions increased and air quality improved. The difference was statistically significant. In addition,concentrations of negative aeroions varied remarkably in different functional areas in the following order:country scenic area > suburban scenic area > city park > traffic artery in Nanning.
Keywords:air negative ions  diurnal variation  functional areas
