Description

technical field [0001] The invention relates to the technical field of hydrological model design, in particular to a design method of a distributed water cycle model based on a multi-source mutual aid water supply model. Background technique [0002] With the improvement of human productivity and the advancement of technology, the impact of human activities on the water cycle has increased significantly, and the evolution of the water cycle in the basin has shown complex natural-artificial characteristics. Most of the traditional hydrological models are developed with the mechanism of flow generation and confluence as the core, and generally focus on the simulation of surface runoff. The treatment of resource development and utilization is relatively rough, and it cannot take into account artificial water withdrawal activities and control decisions. Requirements for refined simulation of strong human disturbance processes. Many experts and scholars from hydrology and hydrol...

Problems solved by technology

[0005] In view of the deficiencies of the current distributed natural-artificial water cycle model in the coupling simulation of natural-artificial water cycle and the development, utilization and regulation of water resources, the present invention is based on the theory of natural-artificial water cycle and uses the SWAT model as a tool to develop a distributed natural-artificial water cycle model. The dynamic cross-feed simulation model of the water cycle, by adding a multi-source mutual aid water supply module, enables the SWAT model to have the functions of dynamic cross-feed simulation between natural and artificial water cycles, water resource development, utilization and regulation, etc. The dynamic mutual-feedback relationship between the water cycle and the artificial collateral water cycle not only reflects the impact of the water cycle process on artificial water intake, but also reflects the real-time intervention of economic and social activities on the water cycle process
