摘　　要：通过大气细颗粒物实时在线源解析技术(质谱直接测量法)采集录入淮安市市区部分特征污染源排放成分谱,对淮安市大气细颗粒物进行在线源解析,获取高时间分辨的颗粒物源解析结果,分析颗粒物来源、季度变化和重污染天气的污染过程,评估形成重污染过程的污染影响因子和影响程度,为区域大气污染综合整治提供重要目标指向,同时也为淮安环境空气PM2.5重度污染实时预警与监控、大气污染源减排方案评估、污染事件监控等提供有效的在线监测技术平台。By means of real- time online source analysis( direct measurement of mass spectrometry) of atmospheric fine particles,the part of emission components information of characteristic pollution sources in Huaian urban area was collected and the relative high temporal resolution results were obtained. The pollution factors and influence degree of the formation process of heavy pollution were evaluated by analyzing the sources of particulate matter,seasonal changes and heavy pollution processes of pollution sources. It can provide an important target point for the comprehensive regulation of regional air pollution. This technology provide effective online platform for real time early warning and monitoring of environmental air PM2. 5pollution and evaluation of emissions scheme for reducing air pollution and monitor of pollution incident.
