随着城市暴雨链式自然灾害发生频率和危害程度的不断加剧，暴雨灾害链及其脆弱性研究已成为管理科学、地理学和水文学等不同学科普遍关注的热点研究领域。面向当前灾害脆弱性计算方法时空尺度低以及缺乏动态性特征等科学问题，突破内涝、洪水、滑坡、泥石流等单一灾害脆弱性研究范畴，开展暴雨灾害链及其动态脆弱性时空表达、综合建模和动态模拟的研究，以揭示暴雨链式灾害的驱动机理、演变模式及时空变化规律。项目提出了顾及灾害链及承灾体时空变化特征的城市暴雨灾害链动态脆弱性时空表达方法，设计了暴雨灾害链网络结构，构建了动态脆弱性的指标模型及空间化方法，并基于多灾害集成建模框架与智能体模型，实现城市暴雨灾害链动态脆弱性的精细化计算与动态模拟。项目成果将为暴雨灾害链风险评估与预警提供理论与方法支撑，丰富现有城市灾害脆弱性的研究内涵与技术体系，提高城市应对链式灾害的弹性能力，推动GIS在地理分析与地理过程模拟研究方向上的发展。

With the increasing frequency and deteriorative influence of storm-induced hazard chain in city-region, study on storm-induced hazard chain and its vulnerability has raised widespread concern of different disciplines, including geography, hydrology, management science, etc. Considering the scientific issues in hazard vulnerability calculation methods including low spatio-temporal scale and ignoring dynamic characteristics, it is necessary to break the vulnerability scope of sole hazard such as waterlogging, flood, landslide, and debris flow. Furthermore, research on spatio-temporal pattern expression, comprehensive modeling, and dynamic simulations of storm-induced hazard chain and its vulnerability should be carried out to uncover the mechanism, variation, and evolution of storm-induced hazard chain. For these reasons, this project proposed a spatio-temporal modeling method for vulnerability assessment of storm-induced hazard chain in city-region with the spatio-temporal variations of hazard chain and hazard-bearing body consideration. Meanwhile, this project designed a net structure for storm-induced hazard chain, and built an index model though spatialization method. Based on this, this study implemented the dynamic simulation and meticulous calculation of dynamic vulnerability of storm-induced hazard chain that are integrated with the multi-hazard modeling framework and agent-based model. The outcomes will provide theoretical and methodological support for risk assessment and hazard warning of storm-induced hazard chain, and enhance resilience of city in response to hazard chain. Moreover, the project enrich the theory and method of existing research on city hazard chain vulnerability, and promote the development of GIS in geoanalysis and simulation of geographic process.
