中国科学院大气灰霾追因与控制研究进展

Research Progress on Formation Mechanism and Control Strategies of Haze in Chinese Academy of Sciences

中科院通过实施"大气灰霾追因与控制"B类先导专项,通过实验模拟、外场观测以及模式模拟等研究对大气灰霾形成机理进行了系统的研究。我国的大气污染由多种排放复合而成,表现为排放源多样,污染物成分复杂、浓度高,不同污染物之间存在相互影响、相互促进的关系。根据灰霾形成特点,现阶段治理的基本思路应该在继续做好源头减排的同时,集中力量解决冬半年重污染问题,在管控措施上进一步增强针对性。

Systematic research on formation mechanism of haze has been carried out in Chinese Academy of Sciences （CAS） by experiment simulation, field observation, and model simulation under the implemented the strategic priority research program of Category B ＂Formation Mechanism and Control Strategy of Haze in China＂. China＇s air pollution is formed by compounding a variety of emissions, showing a variety of sources, complex composition of pollutants, high concentrations, and different pollutants demonstrate the mutual influence and promote each other. According to the characteristics of haze formation, the basic principle of haze control at present stage should keep doing the emission reduction at the source, while focus on solving heavy pollution problems in the winter half, and further enhance the targeted control measures.
