China News Service, Chongqing, October 25 (Reporter Liu Xian) New crown pneumonia, earthquakes, typhoons, floods, emergencies... Cities need to be more "resilient" to resist these risks and quickly recover.
On the 25th, at the "2020 Resilient City·Shangshui City Sustainable Development International Forum" held in Chongqing on the 25th, Meng Jianmin and Chen Xiangsheng, academicians of the Chinese Academy of Engineering, deeply interpreted the concept of resilient cities.
Resilient cities refer to cities that can withstand disasters, reduce losses, rationally allocate resources to quickly recover from disasters, and learn from past disasters to improve disaster resilience.
Meng Jianmin said that each city has a certain degree of resilience, but the degree is different.
He analyzed that the resilient city system is similar to the human life system.
For example, the human body has nervous, urinary, circulatory, respiratory, sports, reproduction, immune systems, and cities involve information, water cycle, energy, logistics, roads, ecology, medical and health systems.

Meng Jianmin has a deep research in resilient hospitals.
In an interview with a reporter from Chinanews.com, he said that in this new crown pneumonia epidemic, the medical systems of various countries have exposed that they are not prepared for this sudden epidemic, many are difficult to respond to, and even their carrying capacity has collapsed.
This reminds major hospitals to adjust their original plans and designs. When a large number of patients are influx, the layout and medical procedures of the hospital can be changed in time to ensure the safety of treating patients and medical staff.
Medical and urban planning and design managers must have the awareness of building resilient hospitals and resilient cities to actively respond to various disasters such as emergencies.
Chen Xiangsheng focused on "super-large resilient city (group) construction".
He believes that resilient cities can accommodate the current and future social (social resilience), economic (economic resilience), environment (ecological resilience) and government management (organizational resilience) pressure brought about by the development.
How to build a super resilient city (group)?
Chen Xiangsheng suggested that one is to conduct a survey of urban risks and establish a classification ledger for urban risks; the other is to apply "resilience engineering" to improve urban resilience; the third is to pay attention to the reliability of urban hidden projects and lifeline systems; the fourth is to use the Internet of Things and big data, etc. Management improves the level of risk monitoring, command and disposal; the fifth is to improve the logistics and supply chain support capabilities.
He concluded that the resilient planning and design of infrastructure in megacities (clusters), including the development and utilization of underground space, especially the transformation of important infrastructure such as lifelines to underground, is the foundation for supporting the resilience of megacities (clusters). To build a super-large city (cluster) "air, sea, and ground" full coverage integrated security intelligent platform, it is necessary to integrate government, commerce, transportation, medical, fire protection, meteorology, environment, public security and other data from multiple departments, and make full use of global perception and the Internet of Things , Cloud computing, artificial intelligence, machine learning and other technologies to perform effective pre-control decision-making, rapid response during the event, and efficient rescue after the event.
