中文摘要：

海岸带是陆域环境和海域环境的交叉和相互作用地带，世界上约有60％的人口居住在这一范围相对较小，但具有高生产力和高价值、动态而敏感的区域。海岸带利用结构与自然、人文资源的开发方式直接相关，其结构由两部分元素组成，一是土地和海洋生态系统，另一是人类社会系统，人类自古以来对海洋的开发就以海岸带为重点和基地。论文根据国际上海岸带利用结构分类，重点分析辽宁海岸带利用结构特征。同时文中应用变差系数、集中化指数、锡尔熵指数（锡尔系数）等定量分析方法，重点分析了辽宁海岸带海洋资源开发利用与海洋经济区域差异形成的原因。

英文摘要：

The coastal zone is the cross-zone between land environment and marine environment. Because of its rich resources, predominant natural conditions, good location and the unique land and sea commonness, coastal zone has become the most concentrated area of human activities. About 60% of the people in the world live in this relatively small area with high productivity and high-value dynamics. The usage structure of the coastal zone is directly related to the developmental ways of natural and human resource, which has two structural elements, one is the ecosystem of land and sea, and the other is system of human society. The coastal zone is the basis of human development on oceans. Based on Liaoning coastal zone＇s types, resources, environment and marine economic development, this paper mainly analyzes the characteristics of the usage structure of the coastal zone in Liaoning in accordance with the international classification of the usage structure of the coastal zones. At the same time, development and utilization of marine resources coastal zones and the reasons of marine economy regional differences are mainly analyzed by applying methods of quantitative analysis, such as variation coefficient, concentration index, Theil coefficient and so on.
