Core Viewpoint - Chengdu's archaeological efforts during the 14th Five-Year Plan period have been integrated into the city's reform strategy, achieving significant results in various areas such as legal framework, academic research, cultural heritage protection, talent development, and utilization of archaeological resources [1][2]. Legal and Regulatory Framework - Chengdu has improved its legal framework for cultural heritage protection, revising the "Chengdu Cultural Relics Protection Management Regulations" in 2020 and issuing the "Chengdu Major Site Protection Regulations" in 2022, establishing a "prior archaeology, then transfer" system [1]. - In 2024, Chengdu introduced a mechanism for reporting disciplinary violations in cultural heritage protection, enhancing accountability among local governments [1]. Archaeological Practices and Innovations - Chengdu pioneered the "Chengdu Model" for pre-archaeological land transfer, mandating archaeological surveys before construction projects, which has effectively protected underground relics while promoting urban development [1][2]. - Over the past five years, nearly 7,000 archaeological investigations have been conducted, covering over 300,000 acres, leading to significant discoveries and facilitating the commencement of over 200 major projects [2]. Policy Innovations - Chengdu implemented the first "volume ratio" reward policy for archaeological sites, allowing preserved cultural heritage sites to be excluded from construction density calculations, thus reconciling the conflict between heritage protection and urban development [2]. - This policy has been recognized by the Ministry of Natural Resources and the National Cultural Heritage Administration as an important innovation to be promoted nationwide [2]. Research and Collaboration - The Chengdu Archaeological Research Institute has undertaken 27 key research projects funded by national and provincial programs, receiving recognition as a key research base for the protection of wooden lacquer artifacts [3]. - The institute collaborates with domestic and international universities, including Harvard University and Ehime University, on various archaeological research projects [3]. Infrastructure and Public Engagement - Chengdu has established the Chengdu Archaeological Center, equipped with advanced technologies for archaeological excavation, and built a 4,500 square meter archaeological specimen storage facility [3]. - The city has actively promoted the construction of national archaeological parks, with several sites receiving public acclaim, and has conducted over 300 educational outreach activities serving more than 26,000 people [3].
