The invention discloses an urban inland inundation modeling prediction method which comprises the following steps: acquiring probability of urban inland inundation by using a modeling method; according to the situation that urban inland inundation is caused as an urban water drainage amount is smaller than an urban precipitation amount because of natural situations, respectively calculating the urban water drainage amount and the urban precipitation amount in a symbolic-graphic combination mode; converting the urban water drainage amount and the urban precipitation amount into an urban water drainage effect diagram and an urban precipitation effect diagram by using software, and overlapping the diagrams, so as to obtain an urban ponding effect diagram. By adopting the processing mode, massive tedious data processing is reduced, urban landforms in practical situations can be taken into account, and the latest urban water drainage situations can be acquired, so that great reference values can be made, and urban inland inundation can be predicted by analyzing the urban ponding effect diagram.
