- Abstract
This study presents the methodology and procedure for risk assessment of flood disasters in Yuquan district, Hohhot City, which was supported by technology of natural disaster risk assessment. On the basis of the standard formulation of natural disaster risk and flood disaster risk index, of which weights were developed using combined weights of entropy, the relative membership degree functions of variable fuzzy set (VFS) theory were calculated using set pair analysis, while level values were calculated using VFSs, including hazard levels, exposure levels, vulnerability levels and restorability levels, and the flood risk level for each assessment unit that is 100m×100m was obtained using the natural disaster index method. The results show that The regions with extremely high risk and high risk are mainly located in the northeast and central regions, and the proportions of the occupied areas are 3.86% and 7.16%, respectively; The study can provide scientific reference in flood risk management for local and national governmental agencies.
