基于RIA的三峡库区水环境分析系统研究

三峡信息系统无法满足水环境综合分析的需要，存在交互性差和表现形式单一等问题。为此，分析RIA模式的特点，运用Flex及数据库技术和Web GIS与.Net技术，构建三峡库区水环境分析系统，设计该系统的框架，阐述中间件等关键技术，并对该系统进行实现。对该系统应用结果表明，Flex技术能够改善系统的交互能力，满足库区水环境综合分析需要，为库区水环境提供了较好的保障。

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.
