摘要

In China, following national economic reform and the opendoor policy in 1978, there has been a rapid industrialization and urbanization of coastal regions which has dramatically changed the environment and ecosystems in these areas [1]. Regions with rapidly growing economies, such as Shanghai and Shenzhen, face the double pressure of limited land area and population growth, and many land reclamation projects have been implemented to create new land from ocean [2,3]. Sea level rise and delta subsidence can also increase the vulnerability of coastal zones [4]. Despite the importance of coastal areas, a comprehensive knowledge of the changes of China's coastline is rare at national scale. Hou et al. [5] recently carried out a coastline change assessment over mainland China using topographic maps of the 1940s and 1960s and Landsat images circa 1990, 2000, 2010 and 2014. They found substantial coastline changes in China.
