摘　　要：简要介绍了构建流域水文系统的必要性、可行性和技术支撑,提出应用Geodatabase模型来进行流域数据组织的观点。以Geodatabase为基础,集成流域中各种要素,定义它们之间相互作用关系,建立流域数据库。特别是对河流网络,水文数据组织,水文数据建模等进行了重点研究,并提出了其技术流程,为流域的研究和建设提供了经验借鉴和新的思路。Hydrological systematic data organization in drainage area for the requirement of capturing, updating, managing and applying of spatial information about drainage area data supplies experience for drainage area data establishment and speeding drainage informatizationby performing key technologies research, developing internet applications and integrating system. This article gives a brief introduction about necessity, feasibility and technological sustainment for drainage area hydrological system construction and a kind of view organizing drainage area data using Geodatabase model. Based on Geodatabase, a drainage database is established by integrating all factors in the drainage area and their interaction is defined. Especially, an emphasis research has been enforced on water net, hydrological data organization and its modeling.The technological procedures put forward supply reference and new idea for drainage area research and construction.
