贵州大学春季校园空气负离子分布特征及其评价 The Air Negative Ions Distribution Characteristics of Spring Schoolyards of Guizhou University and Its Evaluation

以贵州大学春季校园主要功能区为研究对象，对不同天气状态下一天中不同时间段进行空气负离子分布特征的研究及空气质量的评价，为学校师生的生活工作学习环境的管理提升提供科学依据。研究表明，空气负离子具有显著的时空分布特征，因时间及空间的不同而存在差异，空气负离子浓度与空气温度呈反比而与空气相对湿度呈正比关系。 With the main functional areas of Guizhou university in spring as the research object, the charac-ters of air negative ions for different times of different weather condition and air quality are stu-died, which could provide a scientific basis for the management of environment in which students and teachers study, work and live. The paper shows that the air negative ions have remarkable space-time distribution features, which is different because of the different time and space. The air negative ions concentration is inversely proportional with the air temperature and is positively associated with air relative humidity.
