| 摘 要： | 大气灰霾如何产生以及如何控制，不仅是大气科学研究面临的前沿课题，也是我国政府和公众迫切需要解决的重大环境污染问题。中科院开展的“大气灰霾追因与控制”专项将以大气细颗粒物(PM 2.5 )的生成、演化和控制为核心科学问题，以京津冀、长三角、珠三角为研究区域，通过可控实验、外场观测和数值模拟确定致霾污染物的组成及来源，阐明区域灰霾形成的关键物理化学机制，识别关键污染物和污染源，发展具有我国自主知识产权的大气灰霾监测技术以及预测预警及控制决策模型，研发致霾关键污染物的源控制和过程控制技术，为控制灰霾污染提供科学可行的技术和政策解决方案。

| Abstract: | The control strategies for haze in China are not only cutting-edge topics of atmospheric research, but also an urgent issue to be addressed by the Chinese government and the public. Focused on the core scientific issues of the formation, evolution, and control of atmospheric fine particles (PM 2.5 ), this project will carry out a series of laboratory simulations, field observations, and numerical simulations. The research programs aim to determine the composition and sources of pollutants causing haze; to clarify the key physical and chemical mechanisms of regional haze formation in the regions of Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl River Delta; and to identify the key pollutants and sources of pollution. We will develop atmospheric haze monitoring technology, forecast and early warning, control decision-making models, as well as conduct R & D on source and process control technology for key pollutants that induce haze. Thus, the scientific and practical techniques and policy solutions will be provided to control the haze pollution. |
