Technical Field
The invention belongs to the technical field of geographic information, and particularly relates to a full-life-cycle urban water flow process coupling model parameter automatic adaptation method and system.

In recent years, under the dual actions of high-speed urbanization process and global climate change, the urban flood problem is receiving more and more attention. A plurality of new technologies and methods are applied to solving the urban flood problem so as to improve urban water resource management and application capacity, wherein the urban hydrological model is one of core technologies widely applied to urban water resource management and flood disaster response by taking advantages of the urban hydrological model in the aspects of law disclosure, prediction analysis and the like. The modeling and simulation of the urban water flow process are faced with extremely complex urban scenes, and the urban rainfall flood process is influenced and acted by multiple element types, and mainly comprises surface factors (terrain and land utilization), drainage pipe networks, roads, buildings, natural or artificial lakes and the like. This current situation makes modeling and simulation of the urban water flow process extremely complex in terms of model parameter adaptation. Therefore, how to quickly and automatically convert the standardized geographic data describing the real geographic scene into the data format and the input parameters which are adapted to the simulation model of the urban water flow process is the key for improving the application capability of the model.

The existing software system for supporting sponge city construction at home and abroad is realized on the basis of packaging a hydrological model by using a GIS (geographic information system) technology and a computer visualization technology. Software systems developed based on model encapsulation techniques, such as: the software not only improves the visual expression capability of the model, but also improves the data preprocessing and data adaptation capability of the model, but the data preprocessing work of the hydrological model software often needs other software to be matched for realization. In addition, there is no existing commercial model data adaptation program that can develop a data adaptation program in a state where geographic elements such as city subsurface factors (terrain and land utilization), drainage networks, roads, buildings, natural or artificial lakes, etc. are considered as physical objects, and these elements are generalized into different land utilization types to be input into a model structure for calculation and computation.
