摘　　要：针对水利科学数据的特点,研究设计了水利科学数据共享网的总体架构。该共享网是一个分布式的数据交换体系,总体设计思路是利用元数据理论整合分散的水利科学数据资源,通过业务逻辑的技术封装提供水利科学数据的网络共享。共享网由3个层次、5个功能模块组成,其中元数据管理是核心设施。共享网原型系统采用J2EE开发,实现跨平台部署。应用实践表明其构架模式适用于水利科学数据学科特点和共享需求。According to the characteristics of scientific data in water sector, a general framework of the water scientific data sharing network is studied and designed, which is a distributed data exchanging system. The general design concept of the network is to integrate the dispersive water scientific data resources based on the metadata theory, so as to provide the network sharing through the technical encapsulation with the business logic. The network is composed of three levels and five function modules with the metadata management as the core. The archetypal system of the network is developed with J2EE and realizes the transplatform disposal. The practices show that the frame-mode of the network is applicable to the characteristics of the water scientific data and the data sharing requirements.
