摘要
我国是有辽阔海洋国土的海洋大国,海陆总国土面积约1 260×104km2。中国海处于大陆边缘,其海底地貌可分为大陆架、大陆坡、岛弧、海沟和深海海盆五大类。本文按地体构造分析我国海域及邻区的构造,其主体处于欧亚板块的华北亚板块、扬子亚板块、华南亚板块、南海亚板块和东南亚亚板块,其中亚板块可分为若干地体。台湾海岸山脉及其以东区域位于菲律宾海板块。三叠纪以来,这些板块、亚板块和地体处于不断拼合、增生或离散之中。按照联合国海洋法公约,渤海是内海。黄海的西部海域,东海和南海的大部分海域都是我国国家管辖的专属经济区,都是中国海洋国土,根本不是什么公海。我国海洋矿产资源极其丰富,海洋油气资源的勘探与开发居最重要的地位。除了已开采海滨砂矿、铜、煤等固体矿产之外,应特别要重视海洋多金属结核、天然气水合物等资源的勘探和开发。
China is a great marine nation and has the vast marine territory with of approximately 1 260×104 km2.China sea is located in the continental margin and its submarine topography may be divided into 5 types：the continental shelf,the continental slope,the island arc,the trench and the bathymetric basin.According to the terrene tectonic analysis,China Sea area and adjacent regions consist of the Eurasian plate,North China sub-plate,Yangtze sub-plate,the South China sub-plate,the South China Sea sub-plate and Southeast Asian sub-plate,and these plates can be further divided into some terrenes.The Taiwan seacoast sierra and east region are located in the Philippine plate.Since the Triassic period,these tectonic plates and the terrenes experienced collision（amalgamation or accretion） and dispersion.The marine mineral resources of China are extremely rich.The exploration and the development of marine oil gas resources played the most important status.Besides the sea-beach placer,copper,coal,much effort should be made to develop and explore the ocean polymetallic nodule and natural gas hydrate,and so on.
