网格技术为解决数据共享问题提供了解决方案。从网格技术在领域中的应用出发，结合水利数据分布异构性、计算密集、资源分布等问题分析了水利行业对信息网格的需求，设计了一个层次式的、以“服务”为中心的五层水利信息网格体系结构。重点研究了水利元数据管理、元数据目录服务、资源交易服务等关键技术。

英文摘要：

Grid technology provides a solution for data sharing, Based on the application of grid in relevant area and water resources survey which is characterized by data transparent,computing- intensiveness,distribution of resources,requirement analysis of grid is discussed. A new service - oriented and five layered system architecture of information grid in water resources are designed to solve application problems of water resources. Meanwhile, some crucial technologies are discussed in detail, such as metadata management,metadata directory service,resource trading service, etc.
