【摘要】 为满足水利科学数据管理和共享的需要,在分析我国水利信息分类与编码研究现状以及现有分类体系面临的主要问题的基础上,依据水利科学数据所具有的特性,提出了多维组合的水利科学数据分类体系结构,构建了由科学属性、获取方法、数据载体和时空定位组成的多维水利科学数据分类体系,并对其进行了规范化的编码设计,形成了3段18位的多维码编码结构.目前,该分类与编码体系已在水利科学数据共享网中得到实际应用.更多还原

【Abstract】 In order to meet the requirements of management and sharing of water science data,the status quo of research on the classification and code of water information as well as the main problems of the existing classification system were analyzed.A multi-dimensional water science data classification system was put forward based on the characteristics of the water science data.The multi-dimensional water science data classification system consisted of scientific attributes,acquisition methods,data carriers and space-time orientation.The standard codes were designed according to the classification system,and a multi-dimensional code structure with 18 digits was divided into three sections.At present,the classification and code system has been applied in the water science data network.更多还原
