Remote Sensing Application in China’s Coastal Zones and Islands: Recent Progress and Some Suggestions

To summarize the recent achievements and problems of remote sensing application in China’s coastal zones and islands, this study reviews a quantity of typical studies selected from the last decade in a space order of “offshore land area–intertidal zone–offshore waters–island”. Classical remote sensing in land cover change and coastline dynamics is still the research hotspots. With China’s rapid economic development and urbanization, coastal environmental problems become serious. Remote sensing is increasingly applied into research on land subsidence, seawater intrusion, intertidal ecosystem monitoring, mariculture, red tide, and island reef sovereign evidence, which strongly supports China’s ocean strategies. However, the acquirement of remote sensing data still depends largely on foreign satellites; the update frequency of the remote sensing data is low; and different disciplines in this field are often isolated. We propose to promote fusion of multisource data and different disciplines, and ultimately realize high-precision, automatic, and regular monitoring supported by cloud computing at both national and regional levels.
