摘　　要：列表类型数据是生态研究中最为常见的数据形式。在分析列表类型数据特征及其与元数据关系,数据安全和共享策略等问题基础上,提出了生态研究列表类数据管理系统设计和开发方案。研究认为数据集的元数据不仅是对数据集实体的说明,而且一定程度上决定着数据集实体的内容和数量,以及数据集实体之间的内在联系,这种联系正是进行列表类型数据管理依据所在。Tabular data is a common format in ecological research data. Based on the analysis of characteristics of tabulardata, the relationship between dataset and associated metadata, and safety and share strategy, a tabular database system has been designed with Oracle soft package and B/S web databased techniques. The study shows that metadata is not only documents for datasets, but a determination of the content and data volume of datasets as well as the relationships among datasets. The design scheme has been applied in development and establishment of soil conservation database in the Loess Plateau.
