Abstract

The invention provides a soil moisture measurement method and device based on multi-source remote sensing data fusion, which are used for measuring moisture contained in soil in a target area. The method includes: determining a soil moisture estimation result of the target area by acquiring original data of the soil in the target area and measured data of the soil in the target area through a cyclone global navigation satellite system; performing space-time fusion on the obtained first surface temperature data of the target area soil and the obtained second surface temperature data of the target area soil to obtain a surface temperature estimation result; obtaining auxiliary parameters influencing soil moisture, wherein the auxiliary parameters comprise vegetation coverage indexes, the ground elevation, the vegetation coverage, th soil roughness, the ground gradient and the rainfall; and performing data fusion on the soil moisture estimation result, the surface temperature estimation result and the auxiliary parameters to obtain a multi-source remote sensing data fusion model, and obtaining a soil moisture measurement result through the multi-source remote sensing data fusion model. By means of the measuring method, the soil moisture measuring result can be more accurate.

Description

technical field [0001] The invention belongs to the technical field of hydrological remote sensing, and in particular relates to a soil moisture measurement method and device based on fusion of multi-source remote sensing data. Background technique [0002] As a basic parameter in the study of the formation, transformation, and consumption of land surface resources, soil moisture is one of the important parameters of energy and material exchange in the soil-vegetation-atmosphere system, and is also an important determinant of surface energy balance. [0003] Conventional soil moisture surface measurement methods, such as gravimetric measurement and time-domain reflectometry are point-based measurements, which can only represent a small spatial range (0.0025m 2 ), the sampling points are limited and the cost is high. [0004] With the development of remote sensing technology, optical and microwave remote sensing technology has become an important means of estimating soil moi...
