The hydrological data modeling and data sharing are the research focus of watershed science and also the basis of Digital Watershed.Analyzing the domestic and international studies,one can see that watershed information infrastructure integrating observational data and environmental information has become an important application of watershed science on Digital Earth.The hydrological information system of the Heihe River Basin is from the prototype of Arc Hydro model and CUAHSI's Hydrologic Information System,which was designed for a suitable set of the hydrological information system integrating watershed geodatabase,observing system database and data sharing publication system,to achieve the integration of various types of observational data,data sources and observational data in a watershed observation database.Through unified common data model,the surface water and groundwater information are integrated.This system may realize the function of storage,organization and online publication of the watershed relating observed data and spatial data,providing ecological environment online data services as well as the corresponding watershed observational data services for watershed science research and promoting the study of watershed science program.
