- Abstract
Reclamation is an important cause of coastline changes, coastal wetland degradation, and offshore marine pollution. The control and management of reclamation are related to the protection of the national coastal zone and the construction of an ecological civilization. At present, high-frequency remote sensing monitoring of national-scale coastal reclamation types and their spatial distribution is lacking, and the tracking and monitoring of reclamation management measures based on remote sensing methods have not yet been effectively performed. By using the method of integrated remote sensing dynamic monitoring of the coastline and reclamation, and based on Landsat time-series satellite images, the spatial distributions of China's coastal reclamation in the periods of 2010—2015, 2015—2018, and 2018—2020, and the spatial distributions of the measures of returning enclosures to the sea and wetland in the corresponding periods were extracted. The data outcomes were stored in the ArcGIS Shapefile format, and the compressed data volumes totaled 680 KB. The remote sensing dynamic monitoring of national-scale time-series coastal reclamation that is synchronized with the time of coastline change and shared the same satellite image basis is highly significant for the protection of coastline resources and the evaluation of the effect of coastal ecological and environmental management. The results showed that during the second decade of the 21st century, the area of newly coastal reclamation in China declined sharply and that the growth rate of coastal reclamation was effectively controlled. Meanwhile, the rate of measures for returning enclosures to the sea and wetland, which was mostly manifested as the restoration of aquaculture pits and ponds to mudflats and sea surfaces, was increased abruptly, particularly in 2018—2020. Achievements were directly related to the unprecedented strengthening of national policies for reclamation control and coastal zone protection in 2018. The remote sensing monitoring dataset of coastal reclamation dynamics can provide basic data guarantee for national ocean and coastal zone management and scientific research, and important support for the realization of Sustainable Development Goal 14.5.
