Table 1 Triaxial framework and indicators for urban-water interactions
From: Spatiotemporal urban-water interactions in upper Min River settlements within a triaxial framework
Analysis axis | Analysis dimension | Judgment criteria | Main analysis indicators | |
|---|---|---|---|---|
X-axis: Temporal Evolution | Historical stage judgment | Identifying key nodes of structural transformation in urban-water interactions | Coupling stability: Determining whether the state is spontaneous balance, institutionalized stability, or post-disturbance instability | |
Spatial pattern change: Whether structural adjustment or reconstruction occurs around the water system | ||||
System evolutionary resilience: Identifying states of in-situ functional continuity, in-situ narrative translation, ex-situ symbiotic evolution, or catastrophic structural reconstruction | ||||
Y-axis: Spatial Hierarchy | Analysis of spatial scales of influence | Categorizing spatial hierarchies based on the scope, embedding mode, and structural status of the water system within and outside settlements | External level | Site adjacency: riverside, near river, or distant from river |
Macro spatial role: boundary definition, ecological barrier, spatial skeleton, or regional connectivity node | ||||
Internal level | Water entry mode: main stream, tributary, open channel, or underground channel | |||
Water system and spatial pattern: the matching relationship between water systems, streets, and public spaces | ||||
Water landscape: landscape functional types of water spaces | ||||
Z-axis: Functional Mechanism | Dominant function types | Judgment criteria based on dominant functions, allowing for the superposition and transformation of features | Life support orientation: Water system supporting daily water use and sanitation within settlements | |
Ecological buffer orientation:: Water system maintaining ecological safety and resilience of settlements | ||||
Hydraulic infrastructure orientation:Water system supporting local production and disaster prevention | ||||
Defense orientation: Water system as a natural barrier or component of a military system | ||||
Transportation and trade orientation:: Water system supporting regional corridors and trade networks | ||||
Cultural landscape orientation: Water system carrying cultural symbols and tourism value | ||||
Reconstruction and transition orientation: Water system functions redefined during post-disaster recovery or developmental transitions. | ||||
