Research on Hydro-environment Analysis System of Three Gorges Reservoir Based on RIA

In view of the problems about unsatisfactory integration analysis,pool interactive and so on in the information system of Three Gorges reservoir.This paper constructs a hydro-environment analysis system of Three Gorges reservoir after studying the pattern of RIA and Flex technology and using Flex framework,database,Web Geographic Information System(GIS) and.Net technology.It designs the architecture and describes middleware and so on crucial technology,implements the system.Result shows that Flex technology has more efficient interactive capability and richer forms of representation,satisfies the demand for integration analysis,provides a good support for protecting the hydro-environment.
