海岛调查中岛礁的划分问题,关系着对全国岛屿数量的正确统计,关系着对岛礁资源的了解,关系着对岛礁国土的合理开发。文中对现在依据出露水面的面积为标准的单一划分指标进行了讨论;提出以生存条件、出露面积和有否明显的浅滩海岸为依据的三条标志所表征的成因类型、分布形态和组成物质等作为划分依据,并对庙岛群岛的岛礁进行了划分。 The issue of the division of islands and reefs in the island investigation is related to the correct statistics of the number of islands in the country and the understanding of the resources of the islands and reefs, which are also related to the rational development of the islands and reefs. In this paper, we discuss the current single demarcation index based on the area of ​​dew surface, and propose the types of genesis, distribution patterns and compositional materials that are characterized by the living conditions, the exposed area and the obvious shoal coast. As the basis for the division, and the islands and islands of the temple island were divided.
