依据灾害系统理论和中国自然灾害数据库,构建了综合城市化水平(Cl)指标和综合自然灾害强度(QC)指标;运用数字地图技术,在模型与图谱互馈过程中,实现了中国城市承灾体与致灾因子的综合定量评价,编制了中国城市自然灾害区划图。将中国区划为3个一级区,即沿海城市灾害区、东部城市灾害区和西部城市灾害区,以及15个二级区和22个三级区,为城市灾害风险管理和中国自然灾害救助区划提供了科学依据。
Based on the theory of disaster system and the database of natural disasters in China, indicators of integrated urbanization (Cl) and integrated natural disaster intensity (QC) were constructed. By using digital map technology, in the process of interaction between model and map, Body and hazard factors in a comprehensive quantitative evaluation of the preparation of China’s urban natural disaster zoning map. China is divided into three primary districts, namely, the disaster areas in coastal cities, the urban disaster areas in the eastern part of China and the urban disaster areas in the western part of China, as well as 15 second-level districts and 22 third-level districts, which provide urban disaster risk management and China’s natural disaster relief zoning Provide a scientific basis.
