| Abstract: | An integrated urbanization level (CL) index and an integrated natural disaster intensity (QC) index were developed on the
basis of Disaster System Theory and China Natural Disaster Database for integrated urban disaster risk assessment. Integrated
quantitative assessments of the urban socio-economic system and the intensity of hazards in China were carried out by the
Model-Tupu (map series) and inter-feedback process using digital map technology. On the basis of this assessment, China can
be regionalized into three regions, namely, coastal urban disaster region, eastern urban disaster region and western urban
disaster region, 15 sub-regions and 22 units. These results can provide a scientific basis for determining a city’s disaster
risk management and natural disaster relief regionalization in China.
