摘要
岛屿对于发展海洋经济,确定海洋权属,以及国家安全等方面都具有重要地位。因此,岛屿的成因分类研究具有重要理论意义和应用价值。传统上将岛屿分为大陆岛、海洋岛(火山岛与珊瑚岛)和冲积岛。这种分类已经不能适应现代地球学科的新进展。本文根据板块构造理论和大洋地貌体系,提出新的岛屿分类意见,即分为内力和外力两个成因系列,包括近岸大陆岛、隆起大陆岛、大陆火山岛、岛弧陆块岛、岛弧火山岛、俯冲增生岛、无震海岭火山岛、微型陆块岛、海山火山岛、中脊火山岛、构造断层岛、河口沙岛、障壁岛、侵蚀沙岛、珊瑚岛15个类型。
Islands play an important role in marine economic development, oceanic right ascription, and national defense. So, the study of the origin classification of islands is of not only theoretic significance, but is of also important applied value. Traditionally, islands are divided into continental island, oceanic island（volcanic island, coral island） and alluvial island in the ocean. This kind of classification can no longer adapt to match the new progress in the Earth Science today. According to plate tectonic theory and oceanic landforms system, the paper explains the origin of islands, and a new classification system of ocean island is proposed. We divide islands into geotectonic-geomorphic system island（continental terrace island,island of island arc,island of oceanic basin, mid-oceanic ridge island）and exoenetic force-geomorphic system island（sand island,coral island）. At the same time,traditional classification is revised, and islands are divided into continental island, oceanic island （volcanic island and coral island）, sand island and tectonic melange complex island.
