摘　　要：为解决水文信息共享问题,本文从分析水文数据本身固有的特性出发,建立了基于空间数据仓库的具有多层维度和度量属性的水文信息共享数据模型,结合面向对象的思想,提出水文信息单元,并探讨了以之建立水文信息数据仓库的方案。To solve all the problems involved in hydrological data sharing, in this paper, in light of the characteristics of hydrological data, a modal of multi dimensions and measures based on the spatial data warehouse is worked out. To describe and manage above - mentioned modal a method named hydrological data unit, utilizing the entity, which emphasize the characteristics of time and space and the attributes consisted of hydrological and sharing information is proposed on the basis of object. Then a perfect project on we hydrological data sharing constructing of hydrological data unit based on spatial data warehouse and Interact platform （or IHISS） is proposed.
