摘　　要：提出了一种基于空间聚类分析的南海主要航线提取方法,利用2001-2014年VOSClim舰船数据,通过航线生成、航线聚类、聚类中心线提取得到了南海主要航线提取与分级结果,将提取结果与美国中央情报局所得航线进行对比,对南海主要航线分布特征进行分析。分析结果表明：提取出21条南海主要航线,一-三级航线分别有5、6、10条;在21条南海主要航线中,经过南沙群岛周边海域的航线多达14条;在5条一级航线中,分布在南海北部、西部和南部的航线分别有1、2、2条;重要性指数由高到低的前5条航线依次为新加坡—香港、香港—台湾海峡、新加坡—巴拉巴克海峡、新加坡—巴士海峡、新加坡—高雄航线;南海主要航线以西南—东北向为主,新加坡、香港为南海最重要的2个交通枢纽。An extraction method of main routes in South China Sea based on spatial cluster analysis was proposed.The VOSClim ship data in 2001-2014 were used to obtain the extraction and classification result of main routes in South China Sea through route generation,route cluster and cluster centerline extraction.Extraction result was compared with the routes of American Central Intelligence Agency.The distribution characteristics of main routes in South China Sea were analyzed.Analysis result shows that 21 main routes in South China Sea are extracted.There are 5,6and 10 routes for classes one,two and three respectively.Among 21 main routes in South China Sea,up to 14 routes go through the surrounding waters of Nansha Islands.Among 5routes of class one in South China Sea,1,2and 2routes are distributed at the northern,western and southern South China Sea respectively.The first five routes sorted by significance index from high to low are Singapore-Hong Kong,Hong Kong-Taiwan Strait,Singapore-Balabac Strait,Singapore-Bashi Strait and Singapore-Kaohsiung routes successively.The direction of main routes in South China Sea is mainly southwest-northeast.Singapore andHong Kong are two most important transportation hubs in South China Sea.
