Urban water-logging disasters occur frequently in China.The construction of urban drainage and water-logging prevention ca-pacity is an important part of water-logging control.It is very important to evaluate urban drainage capacity and identify weak links in or-der to carry out water-logging control work in time sequence and focus.Taking Jiangbei urban area of Fuzhou as an example,taking drainage zoning as a unit,this paper uses random forest model to evaluate its drainage capacity.The results show that:the evaluation accu-racy of random forest model is 90％,the AUC value is 0.883,the model has high evaluation accuracy,and the model evaluation results can better reflect the actual ponding situation.
