The 21st century is the era of underground space development and utilization, and the sustainable development and high-quality development of underground space have become an international consensus.
The 3rd Shanghai Summit on the Development and Utilization of Urban Underground Space held recently, with the theme of "Building a Low-Carbon And Resilient City and Promoting the Fine Management of Underground Space", focused on the development trend of urban underground space development and utilization such as "flood prevention and disaster reduction", "technological innovation", "resilience and low carbon" and "digital intelligence", and linked countries to exchange and share practical experience and inspiration in the development of underground space, providing lessons for the construction of low-carbon and resilient cities, and providing a theoretical basis for the rational planning and development of underground space development and utilization. Jointly promote the further improvement and development of the development and utilization level of urban underground space.
Qian Qihu, an academician of the Chinese Academy of Engineering, conducted an in-depth discussion on "urban construction and three-dimensional city in the new era under the dual carbon target", focusing on the development and utilization of underground space in urban construction, and providing many feasible ideas and suggestions for building a high-quality ecological environment.
He pointed out that urban development in the new era is facing the severe challenges of global warming and the major pressure of people's growing needs for a better life, so we need to rationally develop and utilize urban underground space, build a resilient city with a high level of disaster prevention and mitigation, and create a "double carbon" city with low carbon emissions in industry, construction, transportation and ecological and artificial carbon sinks.
Shan Dongming, deputy director of the Informatization Promotion Division (Big Data Development Division) of the Shanghai Municipal Commission of Economy and Information Technology, conducted a study on "Thinking on Urban Spatial Reconstruction under the Background of Digital Transformation", which provided new ideas for urban spatial reconstruction, which is of great significance for improving urban management efficiency and saving resources. Under the background of digital transformation, urban spatial reconstruction is facing the trend of "digital base", driven by the two-wheel drive of "technological innovation" and "institutional innovation", and has experienced three transformations: "from 3D to digital twin", "from informatization to knowledge", and "from planning and design to the whole process and the whole ecology". It is also proposed that the data capabilities, knowledge capabilities and algorithm capabilities possessed by the urban digital base in the future will be the correct application of digitalization, networking and intelligence, reflecting the characteristics of self-growth, consciousness and building blocks and combinations.
Wang Hengdong, chief engineer of Shanghai Municipal Engineering Design Institute (Group) Co., Ltd., discussed the "safety control technology of urban underground comprehensive pipe corridor", pointed out the importance of urban underground pipelines to urban safety management, and put forward many guiding suggestions around the safety prevention and control and construction of urban underground pipelines, providing ideas for the areas of the white paper.
He said that underground pipelines are important facilities and lifelines to ensure the operation of the city, and the most urgent issue at present is to find out the "home bottom" of underground pipelines, complete the census of urban underground pipe networks, gradually update the underground pipeline system, and continuously strengthen the construction of urban underground comprehensive pipe corridors.
The conference was jointly sponsored by UN-Habitat, the International Joint Research Center for Underground Space, the Science and Technology Committee of the Shanghai Municipal Housing and Urban-Rural Construction Administration Committee, the Shanghai Urban Science Research Association, and co-hosted by the Shanghai Municipal Engineering Design and Research Institute (Group) Co., Ltd. and the Shanghai World Cities Day Coordination Center. Since 2019, the Shanghai Summit on the Development and Utilization of Urban Underground Space has achieved fruitful results and formulated a series of guiding documents, and the release of the 2019 Shanghai Declaration and the 2020 International Outline for the Development and Utilization of Underground Space is the embodiment of the results of the conference. This year, the conference will summarize the suggestions of experts and scholars attending the meeting, formulate and revise the "White Paper on the Development and Utilization of Future Underground Space", and provide universal and guiding experience for building a resilient city with the ability to adapt to climate change and resist disasters.
