The Conference Theme Unveiled! 大会主题正式揭晓
Best Theme Award最佳主题奖
Underground Space: Beneath-Today, Beyond -Tomorrow!
地下空间：承载今日，通达未来
Theme Overview 主题概述
The theme “地下·明日” derives from “Beneath Today, Beyond Tomorrow”. Its rhythmic parallelism in both Chinese and English echoes the dual dimensions of urban underground space development: beneath the ground of the present lies the blueprint for cities of the future. Marking the 40th anniversary of ACUUS’s founding, this theme serves as both a rational retrospective of past research and a forward-looking vision for future progress. We advocate a systematic mindset to integrate diverse concepts including intelligence, low-carbon green development, ecology, urban resilience, humanity, vitality and high efficiency, breaking the physical constraints of urban space and broadening the horizons of urban imagination. Underground space is not merely an invisible foundation supporting urban functions; it shall also act as a sustainable engine driving the leap forward of human urban civilization.
“地下·明日”，取意于“Beneath Today, Beyond Tomorrow”，以中英文字的韵律呼应城市地下空间发展的双重维度：在当下的“地表之下”，孕育通往未来的城市图景。值此ACUUS成立四十周年之际，本主题既是对过往探索的理性回望，亦是对未来发展的前瞻构想。我们倡导以系统性思维统筹智能、绿色、生态、韧性、人文、活力与高效等多元理念，突破城市空间的物理局限，拓展城市想象的边界。地下空间，不仅是承载城市功能的隐性基底，更应成为推动人类城市文明跃迁的可持续引擎。
