摘　　要：为实现渔业专题电子海图的标准化制定与应用,本文以IHO S-57电子海图国际标准为基础,通过分析海图数据模型和数据结构,并根据渔业专题信息的主要内容和特点,扩展了数据集信息记录中的数据集标识字段,定义了海洋渔业专题电子海图产品的编码规则。在物标和属性类目中增加了渔业专题物标和专题属性,并添加了部分专题属性项(值),从而设计了渔业专题电子海图的数据结构。研究成果将有利于整合、共享与应用海洋渔业信息,促进渔业专题电子海图产品的研发与生产,为渔业生物资源研究与利用、渔业生产与管理以及海洋渔业经济发展等提供规范化信息服务支撑。In order to realize the standardized formulation and application of fishery thematic electronic chart, based on the IHO S-57 international electronic chart standard, this paper analyzes the chart data model and data structure, and according to the main contents and characteristics of fishery thematic information, extends the data set identification field in the data set information record, defines the coding rules of marine fishery thematic electronic chart products. In the category of objects and attributes, fishery thematic objects and thematic attributes are added, and some thematic attribute items(values) are added, so as to design the data structure of fishery thematic electronic chart. The research results will facilitate the integration, sharing and application of marine fishery information, promote the development and production of fishery thematic electronic chart products, and provide standardized information service support for the research and utilization of fishery biological resources, fishery production and management, and marine fishery economic development.
