基于Web的环境决策支持系统

A Web-Based Environmental Decision Support System

本文基于浏览器/服务器模式开发了基于Web的环境决策支持系统(WEDSS),该系统由前台客户端、中间层及后台数据库等三层构成,其所有操作逻辑和事务逻辑由各层服务器完成。客户端只完成展示逻辑的功能,可大大提高系统的安全性、稳定性、可维护性和可扩展性,降低网络负载,提高与用户的交互能力,客户终端只要安装Web浏览器就能同时使用和参与环境系统的分析。该系统为城市规划者和政府管理人员更好地进行环境决策,解决当今人类居住、商务及工业发展三者之间的需求关系提供了一个有效途径,但由于环境问题和潜在解决方案流程在WEDSS系统中量化表述的难度,环境决策支持系统在推广方面还存在一定困难。

The authors describe the development of Environmental Decision Support System based on Spatial Decision Support System （SDSS）, which will help planners and administrators to make right decision. The authors design and implement Web-Based Environmental Decision Support System by using browser-server technology, which will balance competing demands for residential,commercial and industrial development. Especially, it will also contribute to constructing economic activities of a harmonious society. But, the authors also point out that there are some difficulties for us to popularize WEDSS.
