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。

Abstract

Tabular data is a common formativen ecological research data.Based on the analysis of characteristics of tabulardata

the relationship between dataset and associated metadata

and safety and share strategy

atabular database sy stem has been designed with Oracle soft package and databased techniques.the study show sthat met adata is notonly documents for datasets

but a determination of the content and data volume of dat asets as well as the relationships among datasets.The design scheme has been applied in development and est ablishmentof soil conservativeon database in the Loess Plateau.
