摘要/Abstract

摘要： 近年来,农田生态系统NPK养分循环研究已经积累了大量的数据,迫切需要建立可长期保存数据、并为养分循环研究全局决策服务的数据管理系统.本文描述了用于养分循环数据管理的概念模型的设计,并说明构建模型的过程,最后给出依据该模型建立数据库系统应用实例.结果表明,依据模型建立的数据库系统可提供按照时间、地点、专题查询的功能,能够管理野外观测数据、专题图和研究报告等多种类型数据,并快速提取和分析数据.

Abstract: Alarge amount of data have been accumulated from the agro-ecosystem nutrient cycling research during recent years. It is necessary to develop a data management system for global decision-making and for preserving from loss. This paper outlined a conceptual model design based on Entity-Relation (E-R) model, presented the model constructing process from user query,and demonstrated a database system using a given model. The results showed that the database implemented from the designed model could provide the function of querying in terms of time, location and theme, and management of various types of data, such as field observation, theme map and research report, and fast extracting and analysis data with spatio-temporal characteristic.
