城市多灾种关联框架与链式网络的构建思路与方法

Thinking and method of constructing urban multi-disaster association framework and chain network

为解决多灾种关系存在概念重复、缺乏系统性且无法视觉呈现等问题,通过城市综合数据的整合与筛选,分析多灾种的潜在影响,结合空间尺度、时间尺度识别城市灾害相互作用,提出“城市多灾种关联框架”的概念和构建思路,构建多灾种矩阵式框架,并通过灾害链式网络的填充可视化多灾关系,最后结合石家庄市某实际环境进行案例分析。研究结果表明:该方法可厘清目标城市多灾种关系并进行有效的视觉呈现,是地理时空数据一体化研究的尝试。研究结果可为城市复合灾害情景构建研究提供理论参考。

In order to solve the problem of concept repetition,lack of systematicness and inability of visual presentation in the multi-disaster relationship,the potential impact of multiple disasters was analyzed through the integration and screening of urban comprehensive data,and the interaction of urban disasters was identified in combination with spatial scale and time scale.The concept and construction ideas of“urban multi-disaster association framework”were proposed,then the multi-disaster matrix framework was constructed,and the multi-disaster relationship was visualized by filling the disaster chain network.Combined with the actual environment of Shijiazhuang,the case analysis was carried out.The results show that this method can clarify the urban multi-disaster relationship and carry out the effective visual presentation,which is an attempt to the integration of geographical spatiotemporal data.The research results can provide theoretical reference for the scenario construction research of urban composite disasters.
