Abstract：In recent year, urban waterlogging disasters has been increasing significantly in China, causing heavy economic losses. This paper uses precipitation, DEM, population and socio-economic data to evaluate the urban waterlogging disaster risk in Shangqiu. The methodology involves establishing a risk evaluation model for waterlog-ging disasters in Shangqiu based on each factors and their weights; calculating quantitative waterlogging disaster risk index of each factor. Then, the risk index of urban waterlogging disaster in Shangqiu is obtained by superim-posing the data, and the high and low risk areas are divided. It is founded that high-risk areas are mainly located in the central urban area, and the distribution of risk is decreasing from the center to the surrounding area. Final-ly, the evaluation results are tested based on the waterlogging data, and it is founded that the results have high reli-ability.
