摘　　要：以浙江省水利工程数据库建设为背景,详细探讨了数据库建设完成后的维护管理问题,提出了省、市、县三级分工协作的维护模式,并通过临时数据库建立数据维护的安全缓冲区,通过服务器群实现数据的安全备份和网络荷载分解等,最终构建形成一个权限分级明确、数据传输安全可靠、维护快速高效的基于网络运行的工程数据库维护管理系统.With the water resources engineering database of Zhejiang Province as an example, a discussion was made on the manner for maintenance and management of the database after its construction, and a three-level （province, city and county） coordinating mode for maintenance of the database was proposed. By adoption of some valuable techniques, such as the employment of the temporary database for development of security buffer area and the use of serial servers for data copy and reduction of network loads, a water resources engineering database maintenance and management system was developed. The present system operating based on the network is clear in purview classification, reliable in data transfer, and highly efficient in database maintenance.
