Data of coastal construction land around the South China Sea in 2010 and 1975 were extracted and the spatial-temporal characteristics of construction land expansion based on different geomorphologic backgrounds in this period was discussed. Results showed that: (1) In South China Mainland and Malay Peninsula, construction land in coastal zone was generally expanded rapidly; in Indochina, construction land in coastal zone was expanded moderately; in Sumatra, Kalimantan and Philippines, construction land in coastal zone was expanded slowly except Manila Bay. (2) There were significant differences in construction land expansion between different geomorphology types because of natural resources, development difficulty and hinterland area. As there were good conditions of water transport and wide hinterland, construction land in delta plain coast and estuary plain coast expanded rapidly; construction land expansion in mesa coast and barrier - lagoon coast was remarkable due to the suitability for building small or medium-sized ports; construction land expansion in gulf coast and mountain coast was relatively slow because there existed limited development potential; construction land expansion in flat dike coast was even slower because of the limited hinterland and underdeveloped water transport. (3) Development patterns varied according to coastal geomorphologic features. The spatial morphology of construction land was diverse in delta plain coast and estuary plain coast; in mountain coast, mesa coast and gulf plain coast, it presented agglomerating or zonal distribution; in barrier - lagoon coast, it presented agglomerating or star distribution; in flat dyke coast, it presented zonal, linear or point distribution.
