Urban-STA4CLC: Urban Theory-Informed Spatio-Temporal Attention Model for Predicting Post-Disaster Commercial Land Use Change
- 融合城市理论的时空注意力机制,捕捉灾后人流与用地变化关系。
- 在飓风频发场景下F1得分提升19%,达0.8763。
- 适合关注灾后城市恢复与商业用地规划的研究者。
飓风等自然灾害对经济活动造成异常扰动,尤其易重塑商业用地格局,因其对访客流量高度敏感。现有建模方法难以有效捕捉灾后人类活动与商业用地变化之间的复杂互动。本研究基于韧性城市、空间经济与扩散理论,构建了城市理论引导的时空注意力模型(Urban-STA4CLC),用于预测两年内灾害累积影响下普查街区级商业用地的年均衰退与扩张。模型整合了灾情感知的时间注意力模块、多关系空间注意力模块及理论引导的正则化项。在反复飓风情景下,其F1分数达0.8763,较非理论基线提升约19%。消融实验验证了各理论模块的有效性。结果表明,将城市理论嵌入模型可显著增强对用地增减规律的捕捉能力,为考虑多次灾害累积影响与经济活动变迁的用地研究提供新范式。
原文摘要 · Abstract (English)
Natural disasters such as hurricanes and wildfires increasingly introduce unusual disturbance on economic activities, which are especially likely to reshape commercial land use pattern given their sensitive to customer visitation. However, current modeling approaches are limited in capturing such complex interplay between human activities and commercial land use change under and following disturbances. Such interactions have been more effectively captured in current resilient urban planning theories. This study designs and calibrates a Urban Theory-Informed Spatio-Temporal Attention Model for Predicting Post-Disaster Commercial Land Use Change (Urban-STA4CLC) to predict both the yearly decline and expansion of commercial land use at census block level under cumulative impact of disasters on human activities over two years. Guided by urban theories, Urban-STA4CLC integrates both spatial and temporal attention mechanisms with three theory-informed modules. Resilience theory guides a disaster-aware temporal attention module that captures visitation dynamics. Spatial economic theory informs a multi-relational spatial attention module for inter-block representation. Diffusion theory contributes a regularization term that constrains land use transitions. The model performs significantly better than non-theoretical baselines in predicting commercial land use change under the scenario of recurrent hurricanes, with around 19% improvement in F1 score (0.8763). The effectiveness of the theory-guided modules was further validated through ablation studies. The research demonstrates that embedding urban theory into commercial land use modeling models may substantially enhance the capacity to capture its gains and losses. These advances in commercial land use modeling contribute to land use research that accounts for cumulative impacts of recurrent disasters and shifts in economic activity patterns.
