Short summary

Taking a single flood disaster in Lishui city as an example, a rapid and refined assessment of economic loss is studied and verified, which can effectively simulate the distribution of loss ratio and loss value. It includes the construction of land use type and value based on data fusion and an expert questionnaire survey, the fitting and calibration of vulnerability curves based on an existing database and disaster loss reporting, and estimation of loss ratio and loss value by spatial analysis.
