会同森林生态系统定位研究数据管理系统的研建

Development of Eco-DBMS for Huitong Forest Ecosystem Research Station

为了确保数据的安全性和发挥科研数据的利用效率,在全面了解会同森林生态系统定位研究站25年来的常规观测数据的基础上,确定湖南会同森林生态系统定位研究数据管理系统(E co-DBM S)要完成的基本任务和要达到的总体目标,建立了标准地数据库、水文数据库、气象数据库、养分循环数据库.系统开发过程包括五个阶段:可行性分析、系统需求分析、系统设计、系统调试、系统评价和维护;该系统可进行数据录入、查询、修改、统计、排序、系统维护、打印报表并生成子数据库,实现了对该数据库信息的管理.该系统可广泛用于森林生态系统定位研究的各个领域.

For the consideration of safety and higher efficiency of the data in National Key Observation Station-Long-term Huitong Forest Ecosystem Research Station, an ecological database management system （Eco-DBMS） was established with an overview and analysis of the basic data collected during the past 25 years. Based on the fundamental target and global object, four subset databases were developed： they are subset of standard sampling plots, hydrology, microclimate, and nutrient. The system design includes the following five steps： feasibility analysis, system requirements analysis, general system structural designing, system test, and evaluation. This Eco-DBMS can be employed to data input, inquiry, modification, statistical comparison, sorting, print of report forms, and creating sub-database and system maintenance. Therefore, all the databases in the Eco-DBMS were managed smoothly. The Eco-DBMS will be a powerful tool for all kinds of research in the long-term forest ecological observation station.
