Core Viewpoint - Shenzhen is accelerating its development of underground spaces to create a vibrant three-dimensional city, as outlined in the "Shenzhen Underground Space Resource Utilization Plan (2025-2035)" [1][10]. Group 1: Overview of the Plan - The plan includes 48 key development areas for underground space across various districts, with the most in Nanshan District (10 areas) and the least in Dapeng New District (1 area) [3][4][5][6][7]. - By the end of 2020, Shenzhen's total underground space was approximately 104 million square meters, with a per capita underground space of about 5.9 square meters [1]. Group 2: Development Requirements - The development of these 48 "underground cities" will focus on integrating above-ground and underground spaces, particularly around urban function centers and transit hubs [7][8]. - The plan emphasizes the importance of underground transportation facilities, municipal utilities, and commercial services, aiming to create a "10-minute walk" connectivity between underground transit stations and nearby facilities [8]. Group 3: Economic Justification - The direct costs of underground space development are estimated to be 2-3 times that of above-ground construction, making it essential for cities with high population density and land prices, like Shenzhen, to utilize underground space [10]. - Shenzhen's land area is about 1,997 square kilometers, supporting a population of approximately 21 million and generating a GDP of 3.68 trillion yuan in 2024, highlighting the necessity of "digging down" for space [10]. Group 4: Achievements and Future Goals - Shenzhen has achieved several national firsts in underground space development, including the first commercially operated underground space and the largest underground train station in Asia [10]. - The city plans to enhance its underground space utilization with more diverse functions, efficient integration of stations and cities, improved regulatory frameworks, and advanced research in underground space [11].
