摘　　要：以福建农林大学校园为例,在师生出行时间5∶00-23∶00时段,对冬季校园内3种典型用地的空气颗粒物浓度进行了观测,同时测定平均风速、温度、相对湿度、氧气浓度、光照度及噪音量。结果发现:1)3种校园用地的空气颗粒物浓度均呈"双峰单谷"-"V"字型变化,为早(5∶00-7∶00)和晚(19∶00-21∶00)高,中午(15∶00)低;2)3种校园用地不同环境对空气颗粒物浓度的变化规律有一定影响,水面和植物有降低颗粒物浓度的作用;3)空气颗粒物浓度受小气候因子等环境因素影响。The air particulate concentrations in 3 types of land in the winter campus of Fujian Agriculture and Forestry University between 5 ： 00 am and 11 ： 00 pm were measured, and at them same time, the average wind speed, temper- ature, relative humidity, oxygen concentration, illumination and noise exposure were measured. The results showed that ： 1 ） the air particulate concentration in all the 3 types of land had the V - shaped changes, which went up in the morning （5：00 am- 7：00 am） and in the evening （7：00 pm -9：00 pm）, and stayed the lowest at noon （3：00 pm） ; 2） the different environment around the 3 kinds of lands had an influence on the change of air particulate con- centration, which was indicated by the role of water body and plants in reducing the air particulate concentration ; 3 ） The environment factors, such as the mieroclimate factor, may affect the air particulate concentration.
