本研究は、元大都の歴史的水システムを対照シナリオとして、現代北京の洪水レジリエンスを評価した。歴史地理再構築と水理・水文シミュレーション、FAHPを用いて分析した結果、元大都の都市洪水レジリエンス指数（UFRI）は3.44、現代北京は3.28であった。現代北京は排水施設密度で優れるが、単位面積貯留容量が26%減少し、水システムの構造的複雑性が48.4%低下しており、グレーインフラが自然の緩衝機能を完全に代替できていない。
English
This study benchmarks modern Beijing's flood resilience against the historical water system of Yuan Dadu (1267-1368 CE) using historical reconstruction, hydrological-hydrodynamic simulation, and FAHP. Results show Yuan Dadu's UFRI is 3.44 vs. modern Beijing's 3.28, despite modern drainage advantages. A 26% reduction in storage capacity and 48.4% decline in structural complexity indicate gray infrastructure fails to fully substitute natural buffering. Planning strategies integrating distributed micro-storage and topological connectivity are proposed.

In the global GX context
Globally, this paper provides a novel historical baseline approach for urban flood resilience assessment, relevant to climate adaptation planning in rapidly urbanizing alluvial plains. It challenges the sole reliance on gray infrastructure, aligning with nature-based solutions discourse in TCFD/ISSB adaptation contexts.

📄 Abstract（原文）
Urban flood resilience is an important indicator for measuring a city’s capacity to respond to and recover from flood disasters. However, existing assessments often lack a long-term hydrological baseline. This study establishes the historical water system of Yuan Dadu (1267–1368 CE) as a control scenario to benchmark the flood resilience of modern Beijing. By integrating a historical geographic reconstruction with a hydrological–hydrodynamic simulation and the fuzzy analytic hierarchy process (FAHP), the research quantifies structural differences in resilience profiles between the nature-adapted historical system and the modern engineering-dominated system. The results indicate that Yuan Dadu’s urban flood resilience index (UFRI) is 3.44 and modern Beijing’s is 3.28. Despite modern Beijing’s significant advantage in drainage facility density (0.61 km/km2) and emergency management, the system exhibits a functional substitution failure, where gray infrastructure has failed to fully compensate for a 26% reduction in the unit area storage capacity (from 6.4 to 4.7 × 104 m3/km2) and a 48.4% decline in the water system structural complexity. The findings indicate that, in rapidly urbanized cities on alluvial plains with high impervious coverage, expanding drainage networks alone may be insufficient to offset losses in a natural hydraulic buffering capacity. Accordingly, planning strategies are proposed that integrate distributed micro-storage and restore topological connectivity to recreate system-level hydraulic buffering functions.
