生态科学数据元数据及其标准研究

Study on ecological metadata and its standard

在介绍生态科学数据的概念、类型和特点的基础上,分析了生态元数据的属性、构建模式、全集元数据(UML模型)、核心元数据及生态元数据标准。认为元数据是规范生态数据管理和实现生态信息共享的基础,生态科学数据元数据标准研建是其关键的环节,必须深入研究生态元数据标准,以期解决生态科学数据的供需矛盾,实现数据管理的科学化和规范化。

Based on introduction of concept,type and characteristics of ecological data,attributes and construction mode of ecological metadata,metadata collection（UML model）,core metadata and ecological metadata standard were analyzed.It is proposed that metadata is the basis for ecological data management and information sharing,study of ecological metadata standard is the key point,and it must be studied further in order to solve the contradiction between data supply and demand,and to realize scientific and standardized management of ecological data.
