Abstract:

According to the characteristics of the development of flood risk management system, it is necessary to consider both the short-term economic loss caused by certain flood events and long-term flood impacts on the complex socio-economic-environmental system. Based on the two conceptual indicators of ‘Flood Insurance Related Flood Risk (FIRFR )’ and ‘Potential Flood Impacts On Sustainability (PFIOS)’, the statistical characteristics of counties and cities for FIRFR and PFIOS were specifically discussed at the national scale and regional scale. The results indicated that counties and cities distribution characteristics varied greatly for FIRFR and PFIOS whether at the national scale or the regional scale. FIRFR presents "leptokurtic" and "heavy-tailed" frequency distribution patterns and PFIOS frequency distribution presents symmetric pattern. Integrated flood prevention and mitigation countermeasures were put forward in combination with the grade variations of FIRFR and PFIOS in different zones. This can help to improve and supply the current flood risk management system in the context of sustainable development. Also, the study can provide scientific references for the decision making on integrated flood prevention and mitigation that targetted to the regional sustainable development.

Key words: sustainable development, flood hazard, rapid assessment, frequency distribution, integrated flood prevention and mitigation
