英文摘要：

The usage of island concepts in our country is far from standard at present. The same concept being expressed differently in different occasions is just one case in point. An island and its concept is extremely significant to a nation’s politics, economy, eco-environment and national defense security. The legal concept of an island should be authoritative, gearing to the international standard with the conceptual advantages in clarity, accuracy and standard. It is beneficial to protect our maritime rights by using the concept of an island in a standard way.
