摘要：

近年来我国特大城市暴雨链生灾害频发，严重威胁人民的生命财产安全和社会稳定，采取有效应对措施及时进行断链减灾至关重要。本文深入梳理暴雨链生灾害体系，研究当前内涝灾害趋势推演模型以及各类推演模拟成果在灾害链阻断过程中的重要作用，提出模拟推演与综合响应相结合的断链思路，明确各类应急主体在特大城市巨灾应对过程中的响应策略。同时，提出以“预案”“监测”“推演”“协同”“救援”为基础的特大城市暴雨链生灾害总体应对思路，针对突发灾害场景下的多部门预案协同、多维度信息汇聚、多层级精准预警、多队伍联动调度等关键问题提出了完备综合预案体系、构建监测预警网络、提升模拟推演应用、强化联合响应能力、夯实精准救援能力五方面应对方法。并在政策法规制定、标准编制、智慧化技术应用、智能预警与定向发布技术的推广、“全民应急”新格局的形成方面提出了发展建议。

摘要： Formation of new atmospheric aerosol particles is a global phenomenon that has been observed to take place in even heavily-polluted environments. In China, new particle production has been observed at very high pollution levels (condensation sink about 0.1s ) in several megacities. A holistic scientific understanding on the atmospheric phenomena associated with air quality as a whole, as well as on the connection between air quality and climate, is lacking at the moment.With a network of observation stations, we will be able to understand the interactions and feedbacks associated with the urban pollution mixture, and ultimately, are ready to make targeted strategies for the pollution control. This paper summaries the recent advances in studying secondary new aerosol formation in China and shows how increased process-level understanding will help us to understand air quality-climate-weather interactions and how the feedbacks and interactions affect the air quality in highly-polluted environments such as those frequently encountered in Chinese megacities. Formation of new atmospheric aerosol particles is a global phenomenon that has been observed to take place in even heavily-polluted environments. However, in all environments there appears to be a threshold value of the condensation sink (due to pre-existing aerosol particles) after which the formation rate of 3 nm particles is no longer detected. In China, new particle production has been observed at very high pollution levels (condensation sink about 0.1 s ) in several megacities, including Beijing, Shanghai and Nanjing as well as in Pearl River Delta (PRD). Here we summarize the recent findings obtained from these studies and discuss the various implications these findings will have on future research and policy.
