How can megacities be more secure and resilient? Suggestions from the Hangzhou CPPCC special consultation

China News Service, Hangzhou, November 12 (Guo Qiyu, Zhu Ziyang) Megacities have dense populations and facilities, and complex and diverse operating systems. The construction of safety and resilience is not only a must-answer question in urban governance, but also an important part of improving livable quality. On November 12, the Hangzhou Municipal People's Political Consultative Conference of Zhejiang Province held a monthly consultation symposium on "Strengthening the Construction of Safe and Resilient Cities" to provide suggestions and suggestions for the construction of safe and resilient megacities.

Urban security resilience is mainly reflected in the city's risk resistance capabilities, that is, its prevention, response and recovery capabilities in the face of various disasters. In recent years, Hangzhou has systematically promoted institutional construction, urban lifeline projects and digital empowerment to continuously improve urban safety governance capabilities.

For example, in terms of digital intelligence deeply empowering urban security governance, Hangzhou has currently built a "1+1+10+N" smart emergency response framework, which consists of a "Hangxiaoying" intelligent agent, a city safety risk comprehensive monitoring and early warning platform, 10 key application scenarios and N application modules.

“The key to building a safe and resilient city is not to make the city ‘never accumulate water’, but to ensure that water can be supplied under extreme pressure, pollution can not overflow the river, waterlogging can be controlled, and risks can be seen.” Zhao Ping, chief engineer of the Zhejiang Urban and Rural Planning and Design Institute, suggested from the perspective of urban water safety that Hangzhou should focus on optimizing secondary water supply and defense against extreme weather scenarios as the next focus of building a safe and resilient city.

The underground pipe network connects thousands of households and carries core functions such as water supply, drainage, power supply, communications, and gas supply. It is an important part of urban infrastructure. Huang Wenliu, a member of the Hangzhou Municipal People's Political Consultative Conference and deputy director of the Hangzhou Planning and Design Institute, suggested that we continue to promote the construction of "one map" of underground pipeline networks, unify data formats and technical standards, and promote the interactive sharing of various pipeline data; rely on the "one map" data base and real-time monitoring dynamics of underground pipeline networks to build an AI intelligent diagnosis model for the pipeline network to further enhance the safety risk prevention and control capabilities of underground pipeline networks.

Communities are the “nerve endings” of urban governance. How to build the first line of defense to deal with various risks and challenges?

Zhu Jing, a member of the Hangzhou CPPCC and a fourth-level researcher at the Zhejiang Provincial Department of Housing and Urban-Rural Development, mentioned digital empowerment. On the one hand, it integrates IoT sensing, video surveillance, risk monitoring and other data resources to build a community safety and resilience cockpit with a one-screen overview; on the other hand, it extends scenarios such as "AI+ hidden danger investigation", "AI+ early warning response" and "AI+ emergency command" to the community to promote the digitization of the entire process of hidden danger investigation, monitoring and early warning, and emergency dispatch, and realize the transformation from experience governance to data governance.

"The value of social rescue forces has never been just to rush forward after a disaster occurs. More importantly, we have already stood on the city's defense line before a disaster occurs." He Jun, founder of the Gongyang Society and chief captain of the Gongyang Rescue Team, suggested that social rescue forces be included in the "one network" of urban governance, and a collaborative mechanism should be established in the preparation of plans, actual combat drills, and unified dispatch. At the same time, incentive measures should be improved to activate social rescue forces.
