Abstract:
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, 6 and 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 5 routes of class one in South China Sea, 1, 2 and 2 routes 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 and Hong Kong are two most important transportation hubs in South China Sea. 1 tab, 7 figs, 26 refs.
