| Abstract: | 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. |
