摘要:人类生存环境的退化是新世纪全球可持续发展所面临的重大问题,改善大气环境已成为当前乃至今后各级政府所面临的一项重要工作。作为大气资源保护有效手段的大气质量环境自动监测技术就显得十分重要。
大气质量监测是大气污染防治的科学基础,没有量和质的监测,大气污染防治将无的放矢。大气质量监测同时也是检验各项保护工作取得成果的主要方式。但是,常规大气质量监测无法满足信息化时代对大气监测的需要。所以,在监测站合理规划的基础上,采用现代化技术手段进行大气质量监测,实现数据采集、传输和存储及处理的自动化监测是未来大气资源保护的必由之路。自动监测、治理、改善大气、保障地区的可持续发展已为世人所共识,也引起了中央和各级地方政府的高度重视。
本文的工作旨在对南京市环境监测站大气质量自动监测方面做个调研,分析大气质量自动监测国内外的发展现状及趋势,重点探讨了南京市环境质量监测系统组成,监测站点的布设,监测站系统的组成、大气日报年报的生成及大气在线监测技术的前沿。并对监测项目及相关仪器进行了汇总,重点对常规污染物指标SO2、NO2、PM10和O3参数做了详细说明。最后对大气自动体系的完善构建提出了自己的思考。

Abstract:The degradation of the human environment is the he major issues facing global sustainable development in the new century. Improve the atmospheric environment has become an important task current and even future governments at all levels facing. Resource protection as an effective means of atmospheric air quality and environment automatic monitoring technology is very important. Air quality monitoring is the scientific basis for air pollution control, there is no quantitative and qualitative monitoring, air pollution control would be pointless. Air quality monitoring is also made for the protection of test results of the main mode. However, routine air quality monitoring can not satisfy the information age the need for atmospheric monitoring. Therefore, in the monitoring sites on the basis of rational planning, the use of modern technology to conduct air quality monitoring, data collection, transmission and storage and processing automation monitoring is the only way to protect the future of Air Resources. Automatic monitoring, governance, improve the atmosphere, protection of local sustainable development has been the consensus for the people of the world, also caused the central and local governments attach great importance. This work aims on the Nanjing Environmental aspects of air quality monitoring stations to be research, analysis of air quality monitoring status and trends of development at home and abroad, focusing on the environmental quality monitoring system composed of Nanjing, the layout of monitoring sites, monitoring station system components, air-line monitoring system andJournal report generation atmospheric and atmospheric-line monitoring technology in the forefrontAnd monitoring of projects and summarizes the relevant instruments, focusing on the conventional indicators of conventional pollutants SO2, NO2, PM10, and O3 parameters of a detailed description.. Finally, the improvement of atmospheric build automatic system put forward my own thinking。

环境监测发展到第三阶段,随着经济技术发展,原有的监测手段已无法满足需要,环境自动监测系统应运而生。自动监测系统由监测设备、数据采集传输系统、数据查询发布系统组成,系统可以按照预定的采样周期,定时采样分析,并实现数据的传输存储。按照监测的环境要素,环境自动监测系统又分为水质环境自动监测系统、废气污染源自动监测系统、废水污染源自动监测系统、环境大气自动监测系统、辐射环境自动监测系统、噪声环境自动监测系统、汽车尾气自动监测系统等。
