Layered simulation method for surface structures in community

The invention provides a layered simulation method for surface structures in a community, which comprises the step of acquiring building information and further comprises the following steps of: simulating a runoff production process of a building roof by using a hydrological response unit; and simulating the confluence process of the building by using the two-dimensional earth surface model. According to the layering simulation method for the surface structures in the community, the roof water flow runoff process can be simulated, and the surface submerging process of the buildings can also be simulated. 本发明提供一种社区内地表构筑物分层模拟方法，包括获取建筑物信息，还包括以下步骤：使用水文响应单元模拟建筑物屋顶的产流过程；以二维地表模型模拟建筑物本身的汇流过程。本发明提出的一种社区内地表构筑物分层模拟方法，不仅可以模拟屋顶水流径流过程，也可以模拟建筑物的地表淹没过程。
