| 摘 要： | 环境空气颗粒物来源解析受体样品化学组成的时空差异,除受采样点位分布制约外,主要还受采样时间的制约。如何选取时间段及采样周期显得尤为重要。通过青岛市空气自动监测系统近几年获取的颗粒物连续时均值数据,采用统计优化组合选择法,筛选出日均值、年均值的最佳采样时段,可供类似研究参考。

| Abstract: | The space and time difference of ambient air particulate matter origin analysis acceptor sample chemical composition,which is besides restricted by the sampling position distribution,and mainly by the sampling time.How to select the time interval and the sampling period becomes very important.The particulate matter continual hour average data obtained by the Qingdao air automatic monitor system in recent years,which uses the statistics optimum composition trialand-error method,the conclusion of the sampling period representation and the time interval selection is following: In the precondition of reducing sampling cost and obtaining representative result,the sampling of every 5 days is representative etc. |
