PROTECTION AND RESTORATION OF THE ROCKY ISLAND IN SHANGHAI BASED ON THE EROSION MECHANISM: A CASE STUDY OF FUSHAN ISLAND

Through the erosion research of the Fushan rocky island in Shanghai, the type of coastal erosion is defined and the coastline retrogradation rate estimated for the island using the rocky coast evolution model. Schemes for island conservation and restoration are proposed by field survey and in-room investigation. It is suggested that biological barrier be used to reduce the coastal erosion and restore the local ecosystem and herb plants planted to stabilize the marshland between Fushan Island and east Fushan Island. Some engineering and ecological measures are recommended to ease the coastal erosion there.
