文化和自然遗产日丨从“抢救修补”到“智能预防” 数字技术让文化遗产焕发新活力

Core Viewpoint - The theme for China's 9th Cultural and Natural Heritage Day on June 14, 2025, is "Let Cultural Relics Shine with New Vitality." The focus is on the shift from rescue-based protection to preventive protection of cultural heritage, exemplified by the innovative "Digital Cabin" at the Xi'an City Wall [1][3]. Group 1: Digital Protection System - The Xi'an City Wall is the largest and best-preserved ancient city wall in China, utilizing digital technology to create a unique preventive protection system [3]. - The "Digital Cabin" management platform features over 3,000 monitoring points across the city wall, continuously gathering data on critical indicators such as wall cracks, horizontal displacement, and settlement [3][5]. - The system employs artificial intelligence for real-time analysis, enabling 24-hour monitoring of structural changes and automatic alerts to heritage conservation personnel [3][5]. Group 2: Enhanced Monitoring and Emergency Response - The "Digital Cabin" integrates functions for cultural relic protection, tourism operation, emergency management, and flood command, allowing for real-time monitoring and damage prediction of the city wall's structural health [5]. - The approach has transitioned from reactive repairs to preventive protection, establishing a 24/7 "digital sentinel" for cultural heritage [5]. - Following the principle of "minimal intervention and non-destructive detection," a comprehensive risk assessment of the entire 13.74 km wall was conducted, identifying 43 risk hazards, 1,302 voids, and 836 loose areas [7].
