摘要
The tidal flat ridge line is the typical geomorphic feature line of the tidal flat area in radiation sandbank, and it is important for understanding the temporal and spatial changes of the tidal flat with the analysis of the beach ridge lines changes. Based on remote sensing and GIS technology, the tidal flat ridges of radiation sandbank in 1979, 1990, 2002 and 2014 were extracted, and the spatial — temporal changes were systematically analyzed.
