摘　　要：回顾了GIS与水文模型的集成方式,分析了对比分布式水文模型数据库与基础数据库的特点,按照空间数据库的设计步骤,从功能和结构两方面对分布式水文模型数据库进行设计,并建立分布式水文模型数据库,将空间数据库集成到分布式水文模型中。该数据库在模型的运行中起到了枢纽的作用,可以改善分布式水文模型运行环境,提高了运行的整体水平。Integration modes of geographical information system and hydrological model were reviewed. Characters of distributed hydrological model database and fundamental database were compared and analyzed. According to designing steps of spatial database, the distributed hydrological model database was designed and created from the aspects of function and structure. Spatial database was integrated into distributed hydrological model. The distributed hydrological model database played a pivot role in running the model, which improved the operating environment of distributed hydrological model and enhanced the overall level in operating.
