Description

technical field

[0001] The invention relates to a method for accurately measuring the correlation relationship between soil water content and reflectance in the analysis of soil water spectral characteristics, in particular to a soil water reflection spectral characteristic analysis method. Background technique

[0002] Quickly obtaining the spatio-temporal information of soil moisture is of great significance for agriculture, hydrology, geography and other fields. At the same time, the decomposition of mixed pixels of remote sensing images and remote sensing monitoring of other soil attributes require understanding the influence of soil moisture on soil spectral reflectance. Soil spectral reflectance is a comprehensive reflection of the spectral behavior of soil intrinsic physical and chemical properties, so remote sensing technology has broad application prospects in the rapid acquisition of soil moisture spatiotemporal information. Although some studies have pointed out t...
