With the gradual deepening of the implementation of export-oriented economic strategy, marine resources and their regional advantages have become the important factors in the decision process of industrialization. Heavy and chemical industries and the population further aggregating to the coast, become the inevitable trend of economic development, in spite of the vulnerability of coastal ecological environment. Therefore, it is necessary to determine the basic functions of coastal areas, in order to guide coastal area protection and development activities, as a result that the economic, social and ecological benefits will be maximized. Taking the Tianjin as an example, the problems of coastal exploiting are analyzed. Based on the analysis of marine ecological protection areas and the suitability of marine resources and environment, the basic function of the coast is divided, which provides reference for the rational planning of Tianjin coastal resource usage.%随着我国外向型经济战略深入实施,海洋资源及其区位优势成为了决定工业化进程的重要因素.重化工布局和人口进一步向沿海地区聚集成为经济发展必然趋势,而海岸地区是生态环境的脆弱区域,因此,必须通过确定海岸区域的基本功能,来引导海岸区域保护与开发活动,以实现经济、社会和生态效益最大化.以天津市为例,分析了海岸开发利用存在问题.在海洋生态保护区和海洋资源环境适宜性分析基础上,进行了海岸基本功能的划分,为合理规划天津市海岸资源利用提供借鉴.
