China News Service, Beijing, January 21 (Reporter Du Yan and Xu Jing) Improving urban resilience has become an important part of the planning of many cities in China.
At the second session of the 14th Beijing Municipal Committee of the Chinese People's Political Consultative Conference, which opened today, members of the CPPCC offered suggestions and suggestions on "building a livable and resilient smart city and continuing to improve the modernization of megacity governance."
"Resilient cities" refer to cities that have the ability to withstand, adapt to, and quickly recover in adverse environments. They are a new paradigm for urban security development.
Beijing is the first city in the country to incorporate the task of building a resilient city into its overall urban planning.
"With the impact of global climate change and rapid urbanization, Beijing, as a megacity, is facing new challenges." Lu Anhuai, deputy chairman of the Beijing Municipal Committee of the China Democratic League and a professor at the School of Earth and Space Sciences at Peking University, said that last year, the Haihe River Basin had a flood The huge flood caused social concern.
It is recommended that Beijing moderately improve planning flood control standards and make up for the shortcomings of flood control infrastructure.
For example, we will carry out risk removal and reinforcement, dredging and capacity expansion projects for existing large and medium-sized reservoirs; dredge plain river channels and heighten and strengthen embankments; accelerate the planning and construction of key flood storage and detention areas and improve supporting facilities for flood storage and detention areas under construction, and continue to improve river basin flood control Engineering system to enhance the comprehensive flood control and security capabilities of the river basin area.
At the same time, we will carry out in-depth risk assessment and emergency response work in the case of flash floods and debris flows, and continue to improve our ability to defend against extreme weather.
In his view, it is equally important to strengthen the popularization of flood prevention knowledge.
He suggested that "flood prevention science popularization" classes should be set up in Beijing's universities, middle schools, primary schools and kindergartens to strengthen disaster protection drills and effectively improve people's awareness and ability of flood prevention and disaster reduction.
Li Xin, member of the Central Committee for the Democratic Progressive Party, member of the Standing Committee of the Beijing Municipal Committee of the Chinese People's Political Consultative Conference, and director of the Counselor's Office of the Beijing Municipal People's Government, suggested improving meteorological infrastructure standards, encrypting the complex terrain meteorological observation network, improving satellite radar and other multi-dimensional three-dimensional monitoring systems; strengthening research on extreme weather patterns and accelerating Develop more refined meteorological numerical forecast models, promote the application of artificial intelligence technology in extreme weather forecasts, and improve regional, time-based, and intensity-based forecast and warning capabilities.
At the same time, we will take post-disaster reconstruction as an opportunity to gradually withdraw from existing villages in areas prone to flash floods, debris flows, and steep terrain. We will organically combine mountainous rural revitalization, the "Hundred Thousand Projects" and climate resilience construction, focusing on Fangshan and Mentougou. and other disaster-stricken areas to become models of climate resilience construction.
"Establish a comprehensive system of urban disaster monitoring, detection, forecasting and warning, and emergency response safety management that adapts to the characteristics of megacities." Fu Zhibin, member of the Beijing CPPCC Committee, deputy chief engineer of the Construction Comprehensive Survey, Research and Design Institute Co., Ltd., and director of the Geotechnical Engineering Research Institute, believes that, It is necessary to fully develop and utilize intelligent technology, adopt ground sensing, sky-ground integrated monitoring technology, and urban disaster intelligent early warning and emergency response systems, establish a scientific detection, long-term monitoring and real-time early warning technology system and management and control platform for natural disaster prevention and control in Beijing, and improve super-large Professional decision-making and emergency command capabilities for urban disaster prevention and reduction, safety management, and scientific and technological means to help improve the governance level of Beijing's megacities and enhance urban resilience.
Li Yan, member of the Standing Committee of the Central Committee of the Kuomintang Revolutionary Committee, member of the Standing Committee of the Beijing Municipal People's Political Consultative Conference, director and general manager of Beijing Capital Development Holdings (Group) Co., Ltd., believes that building a good urban data system is the basis for improving the refined level of urban governance.
Currently, many data elements have been formed, but the problem of not effectively bridging the digital divide among different industries, regions, and groups still exists.
He believes that building a data system to further meet the needs and expectations of all parties in society and form intelligent and personalized solutions will lay a solid foundation for improving the refinement of urban governance.
At the same time, building a good urban data interaction platform is the core of improving the level of urban co-governance.
Wu Chen, member of the Standing Committee of the Beijing Municipal Committee of the Chinese People's Political Consultative Conference, chair professor at the University of Chinese Academy of Sciences, chief architect and chief planner of the Beijing Institute of Architectural Design and Design, and chief architect of Shougang Group, believes that at this stage, the urban governance decision-making support system is no longer sufficient to adapt to the new situation. To meet the current development needs, there is an urgent need for integrated innovation from the perspective of human settlement science.
It is recommended to actively promote collaborative innovation of urban governance concepts, technologies and systems, improve top-level design, explore and form an effective paradigm for dedicated large-scale model governance, and promote the co-evolution of technology systems and governance systems.
At the end of December last year, Beijing held a special press conference on "Beijing's Resilient City Construction".
At the meeting, the head of the relevant department said that Beijing will compile the "Beijing Resilient City Special Plan" and will focus on five categories: tourist residential facilities, medical emergency services, logistics hubs, highway service area residences, and multi-functional public service facilities. facilities, plan to build a number of "both emergency and emergency" projects, and prepare emergency capacity reserves.
Xu Bin, member of the Standing Committee of the Beijing Municipal Committee of the Chinese People's Political Consultative Conference, member of the Standing Committee of the Beijing Zhigong Party Committee, and chief planner of Hongdu Institute of Beijing Institute of Urban Planning and Design, believes that the "Guidance on the Mixed Use of Functions of Construction Land in Beijing (Trial)" has been issued, and urgent research will be beneficial to Management methods for intensive and economical use of green space guide country parks to reasonably undertake urban functions.
For example, in terms of converting the functions of country parks into "both casual and emergency uses", safety and resilience facilities such as emergency shelters and flood storage and detention areas can usually be used for land with mixed functions and compatible properties such as citizens' leisure and recreation, cultural and sports entertainment, or water, forest, field and grass. Support policies.
Wu Yixia, member of the Standing Committee of the Beijing Municipal Committee of the Chinese People's Political Consultative Conference, member of the Standing Committee of the Beijing Municipal Committee of Jiusan Society, chief landscape architect of China Construction Design and Research Institute Co., Ltd., and chairman of China Construction Culture and Tourism Development Co., Ltd. also suggested that emergency facilities should be combined with public services and tourism service functions to promote Multi-purpose and sustainable disaster prevention and relief facilities.
At the same time, on the basis of meeting the fire protection technical standards, fire prevention facilities such as forest fire passages and observation towers are landscaped, and are compatible with multiple functions such as scenic trails, hiking trails, cycling trails, and observation towers.
Urban rail transit is the development direction of transportation in modern big cities.
By the end of 2023, the total operating mileage of Beijing's urban rail transit has reached 836 kilometers, with an average daily passenger flow of more than 10 million on weekdays. It is one of the lifelines for the safe and efficient operation of the capital city.
Ji Ji, a member of the Beijing Political Consultative Conference from the education sector and dean of the School of Civil and Transportation Engineering at Beijing University of Civil Engineering and Architecture, suggested establishing and improving a "horizontal, vertical and multi-faceted" efficient collaboration mechanism to formulate resilience goals and standards; and rationally select line fortification levels from a resilience perspective. and standard, the track network is optimized and designed according to circles, zones, and categories; for key transfer stations with high passenger flow risks, surrounding cities are used to organically renew land parcels to achieve integrated updates of stations and cities, and improve the resilience of key nodes and line networks.
At the same time, a rail transit resilience assessment system is established to form departmental synergy and self-driving force to continuously improve the governance level of resilient urban rail transit systems.
