The present invention relates to a method for constructing a drainage pipe network data model based on the structure of a multi-aerial root banyan tree. The method includes: classifying urban drainage pipe network facilities into pipe points and pipelines, where the pipelines store the starting pipe points and the ending pipe points to form an urban drainage pipe network, and the data structure is a single main root tree or a multi-aerial root banyan tree structure. A data model is established for the drainage pipe network data through the multi-aerial root banyan tree structure. A longest chain is selected from this tree graph structure as the pivot chain, and sub-tree sets are divided along the pivot chain in the reverse water flow order. Each sub-tree set includes only one such pivot pipe point. The sub-trees are ordered and modeled according to the reverse water flow order of the pivot chain, and thus the data model construction of the entire pipe network can be quickly completed. Through the ordered modeling of the multi-aerial root banyan tree structure data, the present invention lays a solid foundation for information applications such as the acquisition, processing, database building, updating of pipe network data, and urban governance based on pipe network data.
