Abstract:

Cities in China face high and rapidly increasing exposure to disaster risk, calling for effective countermeasures. Reducing disaster vulnerability is a direct and effective way to reduce disaster risk, which requires first and foremost the identification and assessment of vulnerabilities of societies, economies, etc. Economic vulnerability assessment is a significant step in risk evaluation, a prerequisite for effective disaster prevention planning and an important base for emergency management and recovery plan. This paper develops a model for the economic vulnerability assessment, which takes into account of scale of enterprises, vulnerability of industrial sectors, importance of industrial sectors and economic density. Based on the economic vulnerability assessment model, this paper develops an urban economic vulnerability evaluation system, and conducts a case study of Haidian District in Beijing using this system. According to the results, we can identify how many and which blocks are at the level of high and very high economic vulnerability, which can provide useful and practical information for pre-disaster prevention planning, emergency response and recovery plan. Therefore, this evaluation system proves to be effective for economic vulnerability assessment. The economic vulnerability assessment model and the establishment of economic vulnerability assessment system in this paper make it possible for the government to quickly evaluate the economic vulnerability and identify the spatial distribution of vulnerable areas, in all, they are useful explorations into the construction of disaster management information system and will have good application prospects in the area of decision support.

Key words: economic vulnerability, assessment model, evaluation system, Haidian District
