A land consolidation ecological environment dynamic monitoring method based on multi-source remote sensing data

Abstract

The present application relates to the technical field of environmental dynamic monitoring, and discloses a land consolidation ecological environment dynamic monitoring method based on multi-source remote sensing data, which comprises the following steps: performing super-resolution interpolation on a time-series remote sensing data set covering a land consolidation area to obtain a standard remote sensing data set; according to adjacent remote sensing images of the missing optical image in the optical remote sensing image and a synthetic aperture radar image, combining a preset time-series reconstruction pairing model to reconstruct the missing optical image, and replacing the optical remote sensing reconstructed image, calculating the reconstruction residual of the optical remote sensing reconstructed image and the optical remote sensing image, and identifying a real ecological change area of consolidation; generating an ecological index change visual map of the real ecological change area of consolidation according to an updated remote sensing data set; and dynamically monitoring the land consolidation of the ecological environment by using the ecological index change visual map. The present application effectively reduces the alignment difficulty and reconstruction error caused by time-series missing and modal difference, thereby improving the continuity and accuracy of monitoring.
