摘要
南海地理位置重要,自然资源丰富。为维护南海领海主权与国家利益,需要加强对南海诸岛的有效管理与经营。南海海域热带风暴频发,热带风暴带来的灾害严重危害岛礁的经营建设和人民生命安全。以1977—2012年热带风暴数据为基础,通过缓冲区分析和空间拓扑分析等方法分析了南海海域及其岛礁近35 a来受热带风暴影响的状况及规律,以期为国家在经营管理南海诸岛时规避热带风暴灾害提供依据。研究结果表明:1东沙群岛至中沙群岛一带洋面(18°N^21°N,116°E^122°E)是南海海域受热带风暴影响最频繁的地区;2热带风暴对南海岛礁的影响主要集中在夏秋两季(6—11月);3在南海诸岛中,东沙群岛受热带风暴影响最为严重,其次是中沙和西沙群岛,而南沙群岛受热带风暴的影响相对较小。
The South China Sea has crucial geographical value as well as rich natural resources. We should strengthen the management of islands and reefs in this region in order to maintain China＆#39;s ocean sovereignty and national interests. However, the South China Sea is an area where tropical storms take place frequently and the disasters resulting from these tropical storms seriously endanger people＆#39;s lives and islands management. The research was based on tropical storm data from 1977 to 2012 . The authors analyzed conditions and regularity of tropical storms which affected the South China Sea, including its islands and reefs, in the past 35 years through the methods of buffer analysis and statistics of spatially topological relations, with the purpose of providing some foundations of avoiding disasters resulting from tropical storms during the implementation of the management of the islands and reefs in the South China Sea. Some conclusions have been reached： ①The region which is most frequently affected by tropical storms in the South China Sea is the ocean area （18oN^21oN,116oE ~122oE） located from the Dongsha Islands to the Zhongsha Islands;②Tropical storms which impact islands and reefs in the South China Sea mainly take place in summer and autumn （ June to November）;③Among islands and reefs in the South China Sea, the Dongsha Islands seem to be an area most severely affected by tropical storms, followed by the Zhongsha Islands and the Xisha Islands, with the Spratlys being less affected by tropical storms.
