Abstract

The application relates to a method and a device for acquiring soil moisture information, computer equipment and a storage medium. The method comprises the following steps: acquiring vegetation indexinformation and multi-source surface temperature information of a target area, wherein the multi-source surface temperature information at least includes first surface temperature information and second surface temperature information, the first surface temperature information is the surface temperature data of each clear sky day, and the spatial scale of the first surface temperature informationis smaller than the spatial scale of the second surface temperature information; spatially fusing the first surface temperature information and the second surface temperature information according tothe spatial scale of the first surface temperature information, and calculating the fused surface temperature information of the target area; calculating the temperature vegetation drought index information of the target area according to the vegetation index information and the fused surface temperature information; calculating the soil moisture information of the target area according to the temperature vegetation drought index information. By adopting the method, the accuracy of soil moisture information can be improved.

Description

technical field [0001] The present application relates to the field of satellite remote sensing technology, in particular to a soil moisture information acquisition method, device, computer equipment and storage medium. Background technique [0002] Soil moisture is an important part of energy, water, and carbon cycles, so soil moisture information is crucial to the study of agricultural hydrological cycles and crop production, and can provide reliable flux boundary conditions for land-atmosphere models, hydrological models, and precipitation forecast models. At the same time, it has important value in agricultural drought monitoring, irrigation system optimization and agricultural water resource management. Traditionally, soil moisture is mainly obtained by on-site measurement such as weighing method, time domain reflectometer and real-time monitoring system. However, the regional soil moisture data obtained by the soil moisture spatial interpolation method at each on-site ...
