Based on database technology,GIS technology and software engineering methods,this paper tries to design the database functionality ofChina's land-based water system comprehensive simulation and virtual reality platform,which is the core software platform of the CAS Knowledge Innovation Program key project Trans-basin water transfer and its impact on terrestrial water cycle and water safety.Using GIS software and commercial databases,amulti-source database for regional water systemis established,with the diversity of spatial distribution,time scales,and data format,based on the integrated spatial-temporal strategy and the multi-database establishment frame,which effectively eliminate the effect of information silos,to achieve comprehensive utilization of data related to trans-basin water resources,and to provide integrated data support services for the platform.
