大气污染沉降监测方法研究进展

Research progresses on deposition monitoring of air pollution

系统回顾了大气污染沉降监测方法的研究进展,探讨主要面临问题及未来发展方向.现有大气污染沉降监测技术主要包括地面监测、遥感反演等,并在全球、区域与局地等不同尺度上取得系列初步成果.然而,大气沉降成因机制复杂、时空异质性规律显著,现有方法均难以兼顾精度与时空代表性等多方面监测需求,发展新一代监测技术以及多技术集成融合是未来大气沉降精准监测的潜在趋势.深刻了解大气污染沉降监测的研究现状与瓶颈问题有助于进一步系统构建大气污染监测体系、精准感知大气污染多维时空演化的本质规律,为环境治理提供科学的理论支持.

This study overviewed the research progresses of atmospheric deposition monitoring,and also summarized the main challenges and future directions.The common approaches of the deposition monitoring included ground monitoring,model simulation,and remote sensing,which had been widely applied at global,regional and local scales.Though the great achievements,it still faced serious challenges in high accuracy and spatial-temporal representativeness because of the complex formation and evolution of the deposition.Therefore,new generation of monitoring technology and multi-technologies integration will be required in the future researches.By overviewing the progresses and limitations of the current approaches,it is very helpful for capturing the mechanism of multi-scales evolution of air pollution and building the monitoring system,but also providing the theoretical basis for environmental management.
