摘　　要：本文以福建水利电力职业技术学院校园为对象,以学生活动时间(6:00-22:00)为测定时间段,定点定时对校园不同区域的负氧离子及PM2.5浓度进行测定,同时测定了噪声大小来间接表示学生活动量,总结了不同区域不同时段负氧离子及PM2.5浓度的变化趋势。结果表明,翠竹园和大禹广场的负氧离子浓度变化主要受植物光合作用影响,而PM2.5浓度主要受学生活动影响。学生社区、教学区和操场的负氧离子浓度与PM2.5浓度呈负相关,PM2.5浓度与噪声大小呈正相关,即负氧离子浓度与PM2.5浓度主要受学生活动影响。This paper took the campus of Fujian College of Water Conservancy and Electric Power as the object,took the student activity time(6:00-22:00)as the measurement time period,determined the concentration of negative oxygen ions and PM2.5 in different areas of the campus at fixed points,measured the amount of noise to indirectly indicate the amount of student activity at the same time,and summarized the trend of negative oxygen ions and PM2.5 concentration in different regions and different periods.The results showed that the negative oxygen ion concentration changes in Cuizhu Garden and Dayu Plaza were mainly affected by plant photosynthesis,while the PM2.5 concentration was mainly affected by student activities.The concentration of negative oxygen ions in student communities,teaching areas and playgrounds was negatively correlated with the concentration of PM2.5,and the concentration of PM2.5 was positively correlated with the level of noise,that was,the concentration of negative oxygen ions and PM2.5 were mainly affected by student activities.
