【 摘 要 】

Coastline is an important representation of the development and evolution of coastal geomorphologic. As the relying carrier of sea development activities, the scientific management of the sea coastline is of great importance for the rational allocation of marine resources, guidance of sea industrial layout, and promotion of the coastal ecological civilization construction. From the view of monitoring and integrated management of the silty coast space resource, this paper discussed the shoreline types and characteristics of typical shoreline indicators such as the high tide line, wet land line, seawall line, embankment line, vegetation lines, waterlines, etc. Taking the central coast in Jiangsu Province as research area, this study used remote sensing technology to extract the typical shoreline indicators based on two images-ETM/Landsat-7 and OLI / Landsat-8 in 2014, and analyzed the spatial distribution of the coastline indicators and coastal evolution characteristics using the baseline and statistical methods. The research results can provide a reference for the integrated management research and practice of the shoreline space resources.
