Characteristics of Submarine Geomorphology,Natural Resources Distribution and Border Intermittent Lines of the South China Sea

The South China Sea is a marginal sea between Continental Asia and the Pacific Ocean. By analyzing its formation and geomorphological characteristics, especially in use of the submarine Digital Terrain Model (DTM) of the South China Sea, the main geomorphology includes a rhomb shaped oceanic central basin, block_stepping_shaped continental slopes on both sides of the central basin, and continental shelves that mainly distribute on the north, west and south side of the South China Sea, and extend down from the Asia continent. To understand the submarine geomorphologic features is meaningful for territorial protection and economic constructions. The South China Sea is of rich oil, gas hydrate and other oceanic mineral resources. These make this area increasingly important in the development of our national economy. After World War II, the then Chinese government published The Location Map of the South China Sea Islands in 1947 based on historical tradition of administration of the sea, which announced the intermittent lines indicating the oceanic boundary of China territory in the South China Sea, and was widely recognized by the international community according to The Announcement of Potsdam and other international treaties. This paper has precisely calculated the geographic coordinates of these intermittent lines, and highlighted its historical inheritability, and tremendous economic and political significances.
