论冲绳海槽在东海大陆架划界中的意义——以自然地理特征为视角

东海大陆架与中国东部大陆是一个完整的地理单元,东海大陆架是中国大陆在水下的延伸,连续延伸至冲绳海槽。冲绳海槽位于亚欧板块与菲律宾板块的交界处,地质运动活跃,已经逐渐脱离大陆的性质具备洋壳或准洋壳的性质,成为中日大陆架的天然分界线。在东海大陆架划界问题上日本主张"等距离中间线原则",但是"等距离中间线原则"不具有普遍适用性,也不能达到公平的结果。而应当适用"公平原则",考虑多种因素。"自然延伸原则"是大陆架制度的权利依据,而且我国是大陆架自然延伸超过200海里的国家,所以应将大陆架的自然延伸作为中日东海大陆架划界的主要考虑因素。

The role of Okinawa trough in delimitation of East China Sea:A perspective of features of physical geography

On the issue of delimitation of the continental shelf in East China Sea and exclusive economic zone, Japan stuck to break the principle of natural prolongation, urged the principle of midline. This paper will give a perspec-tive of physical geography, demonstrates Okinawa trough is natural boundary of continental shelf in East China Sea. And combining with international law, discussion on the benefit of complying with the fairness principle in the de-limitation of the continental shelf, and abiding by the fairness principle is that made the principle of "natural prolongation" as the main consideration.
