摘要:

南沙争端的起源与发展错综复杂,以文字材料表现不直观,难以快速、全面地理解争端的历史进程。研究引入可视化表达技术,通过从文字材料中收集争端事件,利用统计图表、社会网络和GIS技术对南沙群岛历史事件演化的时空特征进行可视化表达。结果表明,3种可视化表达方法有效地表达了历史事件时空演化过程,反映南沙争端演化的4个阶段(殖民期、和平期、侵占期和稳定期),突出各国重点关注的岛礁类型,发现越南历史事件覆盖的岛礁面广,菲律宾引发的争端事件多。

Abstract:

The Nansha Islands and its neighboring region is Chinese traditional territory. The region has very important strategic value for the abundant oil and gas resources, the significant position of shipping lane. Neighboring countries in the South China Sea have been occupied Chinese Nansha reefs and robbing the oil and gas resources since the 20th century. A complex situation has been formed. Current research about the Nansha dispute give priority to with text. It is counter-intuitive, slow and one-sided to describe the evolvement rules of the Nansha dispute by using text description. In this study, three visualization methods were introduced to reveal the spatial-temporal variation rules of historical events in the Nansha Islands. First, the dispute incidents were collected and preprocessed from a large number of related texts. Then the spatial-temporal characteristics of historical events in the Nansha Islands were analyzed through statistical charts, social network and geographic information system. The results showed that: 1) the evolution of the Nansha islands dispute since the 20th century could be divided into four stages: the colonial period (from 1900 to 1950), peaceful period (from 1950 to 1970), occupation period (from 1970 to 2000) and stability period (from 2000 to 2012). 2) Critical focus reefs by neighboring countries could be divided into reefs with rich oil and gas resources (such as Zengmu Ansha, Wan’an Tan, Liyue Tan etc.) and reefs with superior natural condition (such as Taiping Dao, Zhongye Dao, Nanwei Dao, Nanzi Dao, Hongxiu Dao etc.); 3) The change of Vietnamese events was mainly in the period from 1970 to 2000. The spatial expansion of the events started at Nanwei Dao in the middle part of the Nansha Islands, then enlarged towards the east, the north and the south, and formed four cores of events distribution which included Nanwei Dao, Anbo Shazhou, Northern reefs and Wan’an Tan. Until 2010, the events of Vietnam had covered all of the Nansha reefs. 4) Unlike Vietnam, the events number of Philippine increases progressively with years. These events were mainly located at the north of the Nansha Islands. There were many inflammatory incidents related to Philippine in the Nansha Islands. Philippine had formed four cores of events included Taiping Dao, Zhongye Dao, Liyue Tan and Meiji Jiao with time according to the spatial distribution of events.
