Core Viewpoint - The Ministry of Natural Resources has recognized the "three-dimensional space" composite land supply model implemented at Suzhou East Station as a national demonstration for the rational development and utilization of underground space [1] Group 1: Project Overview - Suzhou East Station is the first underground high-speed railway station in Jiangsu Province and the first in the Yangtze River Delta to achieve the integration of four networks: high-speed rail, intercity, regional rail, and urban rail [1] - The project is located in Suzhou Industrial Park, covering an initial development area of approximately 9 hectares, with a total construction area of about 150,000 square meters, including an underground area of approximately 66,000 square meters at a depth of 40 meters [1] - The project aims to create a vibrant new city through integrated development of above-ground and underground spaces, connecting six major systems seamlessly [1] Group 2: Innovative Aspects - The core innovation of the project is the implementation of the "three-dimensional space" land transfer scheme, which addresses complex spatial ownership issues in station-city integrated development [1] - By breaking away from traditional two-dimensional management, the project utilizes three-dimensional land planning to define underground space rights, facilitating a transition from two-dimensional to three-dimensional representation [1] - This model clarifies the underground space as a supporting property of the above-ground space, providing integrated land use rights for both above and below ground, effectively resolving planning and spatial integration challenges [1] Group 3: Future Development and Impact - Construction of the project is set to officially commence in August 2024, with plans for phased operation starting in 2027 [2] - The underground space will accommodate functions such as station hall, platform, transportation, parking, commercial facilities, and urban corridors, while the above-ground will focus on commercial, hotel, R&D offices, cultural and sports facilities, and an energy center [2] - Experts indicate that the Suzhou East Station case enhances the precision and efficiency of land resource allocation and explores an integrated path for planning, construction, and management in railway hub areas, contributing significantly to the rational development of underground space and promoting high-quality urban development [2]
