【摘要】：中国的南沙群岛位于南海南部,岛礁星罗棋布,但受到岛礁自身面积及其他自然条件的限制,自持力和承载能力都较差,需要外界的持续补给才能维持大量人口的活动。南沙岛礁远离大陆,分布于被称为"危险地带"的珊瑚礁丛中,补给受到很大影响。目前,南沙群岛的岛礁部分被菲律宾、越南和马来西亚等国非法侵占,这些被其他国家非法控制的岛屿和沙洲的控制态势对其周边的海域产生一定的控制,并且将对通过的船舶产生较大的影响。针对南沙岛礁补给困难和控制态势复杂的现状,本文从南沙岛礁的自然条件和控制态势入手,提出了一种基于最小累积成本距离和加权Voronoi图的综合可达性指数,通过建立水深与航行成本的分级对应关系,构建了南沙岛礁及周边港口可达性评价模型,计算了南沙23个岛礁和周边国家9个重要港口之间的综合可达性指数,通过分析南沙主要岛礁和周边国家重要港口之间的综合可达性的优劣,可以为中国在南沙建设补给和中转基地选址提供决策参考。可以为中国开发和管理南沙群岛、制定海洋发展战略提供依据。
[Abstract]:The Spratly Islands is located in the south of Chinese, South China Sea Islands dotted, but by their own island area and other natural conditions, holding force and bearing capacity are poor, continue to supply outside of the need to maintain a large population. The Nansha islands from the mainland, located in known as the "danger zone" coral reefs in supply by great influence. At present, the reefs part of Spratly Islands by the Philippines, Vietnam and Malaysia and other countries illegally occupied by other countries, control the situation of these illegal control of the islands and shoals of the surrounding sea area have some control, and will have a greater impact on the ship. According to the present situation of the Nansha islands difficult supply and control situation the complex, from the natural conditions and the control of the Nansha islands and the trend of a minimum cumulative cost distance and weighted Voronoi diagram based on Ensemble With accessibility index, through established the corresponding relationship between the classification of water depth and navigation cost, construction of the Nansha islands and the surrounding port accessibility evaluation model, the 23 islands between Nansha and neighboring countries 9 important port comprehensive accessibility index was calculated through the analysis of the main reef island between Nansha and neighboring countries an important port of comprehensive accessibility the advantages and disadvantages, can Chinese location provide reference in the construction of Nansha supply and transit base. For China development and management of Spratly Islands, provide the basis for the development of marine development strategy.

【正文快照】： 1前言南沙群岛位于南海的南部,是中国南海诸岛中位置最南的群岛。20世纪60年代以来,随着南沙群岛海域油气资源的勘探和开发,周边国家纷纷以各种手段非法窃取和强占了许多岛礁,特别是岛屿和沙洲。目前,中国(包括台湾省)驻守的有8个岛礁,菲律宾、越南和马来西亚非法侵占了40多个
