摘　　要：在总结环境空气质量自动监测站运行和维护经验的基础上,发现了采样流量、采样管道、纸带走纸精确度、相对湿度等为影响PM2.5的质量浓度的主要影响因素,并对其影响因素提出了相应的控制方法,以最大限度地减小误差、保证PM_(2.5)监测数据的质量。为提高环境监测能力、加强环境执法监管提供可靠依据。Based on the operation and maintenance of on-line ambient air quality monitoring system, this study summarized the flux, pipeline of sampling, precision of fihers tape and relative humidity were the main influencing factors on PM2. 5 concentration. This study also proposed corresponding control methods to reduce system error of on-line monitoring system, guarantee the quality of PMz 5 monitoring data. This study had provided reliable basis for the improvement of environmental monitoring ability and strengthen of environmental law-enforcing supervision.
