Hydrological component analysis method, device and equipment and storage medium

The embodiment of the invention discloses a hydrological component analysis method, device and equipment and a storage medium, and the method comprises the steps: obtaining a target watershed and corresponding geographic meteorological data, and simulating the surface water change data of the target watershed through an SWAT model according to the geographic meteorological data; according to the surface water change data, simulating underground water change data of the target drainage basin through an MODFLOW model; updating the underground water change data as one item of data in the geographic and meteorological data, and returning to the step of simulating the surface water change data of the target drainage basin through the SWAT model according to the geographic and meteorological data until the simulation condition reaches the hydrological component analysis time limit; and performing statistics on surface water change data and underground water change data within the hydrological component analysis per
