摘要
PM 2.5已经日渐成为大气中首要的污染物。同时越来越多的研究表明,PM 2.5污染对人们的正常生活会造成严重的影响,有效监测其空间分布对污染防治和健康影响等具有重要意义。利用遥感技术开展PM 2.5监测已经成为重要且有效的手段,遥感影像的空间分辨率不断提高、PM 2.5遥感反演模型的推陈出新,进一步助推和加深了遥感技术在PM 2.5监测领域中的应用。本文通过归纳总结用于PM 2.5反演的主要遥感数据源,并结合PM 2.5遥感反演模型的基本原理,从不同数据源角度综述了PM 2.5遥感监测技术的研究进展,最后展望了现有监测技术存在的问题以及发展趋势,为开展PM 2.5遥感监测和深化应用提供理论支撑。
PM 2.5 has become the primary atmospheric pollutants.With the knowledge and understanding of PM 2.5,people realized the seriousness of the pollution gradually.Monitoring the spatial distribution of PM 2.5 effectively has great significance to pollution prevention and health effects.With the constant improvement of the remote sensing data resolution and remote sensing retrieval model,it has increasingly become important means in the field of environmental monitoring and earth observation.This paper summarizes the main sources of remote sensing data for PM 2.5 retrieval and the basic principle of remote sensing PM 2.5 retrieval model.The paper also summarized the research progress of PM 2.5 remote sensing monitoring technology from the perspective of different data source.Finally,this paper prospects the existing problems of monitoring technology and its development trend,hoping for provide a theoretical basis on PM 2.5 remote sensing retrieval model building and deepening application.
