实景三维中国让城市管理向“新”向“智”行 赋能多领域更好服务民生

Core Viewpoint - The implementation of 3D modeling technology in urban planning and management is advancing rapidly in China, with nearly 300 cities having completed building models, significantly enhancing urban management and digital economy capabilities [1][3][5]. Group 1: 3D Modeling Technology Development - As of now, nearly 300 cities have completed the production of 3D building models, supporting urban renewal and enhancing the quality of life [1][3]. - By the end of 2025, China aims to establish a comprehensive 3D visualization system, with data elements already organized and scaled [3][7]. - The 3D technology system is characterized by intelligent modeling production, integrated management, and knowledge-based service applications [1][5]. Group 2: Applications in Urban Management - The 3D technology has been integrated into various sectors, including urban planning, disaster prevention, and cultural heritage protection, forming a nationwide data-sharing network [5][19]. - In Fuzhou, the 3D modeling has empowered over 60 fields, particularly enhancing urban management through real-time interaction with city infrastructure [8][10]. - The Fuzhou smart city management platform has created a 3D data foundation covering 188 square kilometers, enabling comprehensive spatial awareness and dynamic monitoring [14][16]. Group 3: Water Management Innovations - Fuzhou has utilized 3D modeling for urban water system management, completing models for 107 rivers and over 30 drainage stations, which aids in flood response and decision-making [19][21]. - The integration of IoT data allows for real-time simulation of flooding scenarios, significantly improving emergency response times during typhoons [23][31]. - The scientific scheduling system for water management has achieved an 88% peak flood reduction rate and a 50% reduction in average drainage response time [31].
