METHOD FOR REMOTE DETERMINATION OF DYNAMICS OF PYROGENIC VEGETATION SUCCESSIONS Russian patent published in 2024 - IPC G01C11/00 

FIELD: agriculture.

SUBSTANCE: invention is intended to determine the dynamics of pyrogenic plant successions. In analogous areas, preliminary photo reference and geobotanical descriptions of vegetation on burnt spots at different times in the summer are carried out. Remote digital spectroradiometric spectrozonal photography of terrestrial landscapes affected by fire is carried out using aircraft, from its beginning until the moment of restoration of natural plant communities with a frequency corresponding to the phases of restoration of plant communities, as well as surfaces in the absence of vegetation. Ground-based digital spectral surveys of the specified landscapes are carried out using a spectroradiometer in the range from 320 to 1100 nm. Spectrozonal images are converted into colour-synthesized ones based on the NDVI vegetation index and albedo. Geographic information analysis and classification of the obtained images are carried out according to pixels assigned to plant communities, undamaged and damaged as a result of fire, taking into account field photo reference data and spectral measurements of the reflected energy of areas with established pyrogenic damage to the phytocenosis. Based on the classification results, the contours of the indicated plant communities are identified, as well as the contours of the surface with a natural absence of vegetation. The average albedo in the contours is determined. Cartographic layers and maps of the dynamics of the average albedo value of phytocenoses are created in the contours of pyrogenic damage relative to the average albedo value of a phytocenosis not damaged by fire, similar in albedo levels. The dynamics of pyrogenic plant successions are revealed by changes in the value of the average albedo in the contours traversed by the fire, relative to the albedo of the undamaged plant community.

EFFECT: remote determination of the dynamics of pyrogenic vegetation succession.
