Problems solved by technology

[0003] The traditional surface water consumption is mainly calculated directly through the irrigation mechanism, or indirectly calculated using the typical field method. Due to the use of fixed empirical data for estimation, the accuracy is low, which is not conducive to the rational allocation and adjustment of water resources in irrigation areas.

Abstract

The invention relates to a surface water consumption calculation method and device, computer equipment and a storage medium. The method comprises the steps: selecting land surface parameters, historical soil moisture data and historical rainfall data of a to-be-used area at a preset moment for data processing, and calculating soil moisture under a preset spatial resolution; selecting multi-sourcesurface parameters and atmospheric driving data of the to-be-used water area at the preset moment, and obtaining an actual evapotranspiration value under the preset spatial resolution according to themulti-source surface parameters and the atmospheric driving data; according to the historical rainfall data at the preset moment, the soil moisture under the preset spatial resolution and the actualevapotranspiration value under the preset spatial resolution, calculating the surface water consumption of the to-be-used area under the preset spatial resolution. By adopting the method, the spatialdistribution condition of water resources can be mastered in an irrigation area, and then reasonable adjustment and management are carried out.

Description

Technical field [0001] This application relates to the technical field of satellite remote sensing, in particular to a method, device, computer equipment and storage medium for calculating surface water consumption. Background technique [0002] Accurate acquisition of agricultural surface water consumption is of great significance for agricultural irrigation monitoring, irrigation system optimization in irrigation areas, and water resources allocation and management in irrigation areas. [0003] Traditional surface water consumption is mainly calculated directly through irrigation mechanisms or indirectly calculated using typical field methods. Due to the use of fixed empirical data for estimation, the accuracy is low, which is not conducive to the rational allocation and adjustment of water resources in the irrigation area. Summary of the invention [0004] Based on this, it is necessary to provide a surface water consumption calculation method, device, computer equipment and stor...
