页面无刷新技术在东莞市三防决策支持系统中的分析与实现

The analysis and implementation of page-without-refresh technology in the supporting system of three resistences in Dongguan city

利用ArcGIS Server和JSF技术开发了一种基于Web的三防决策支持系统,采用Ajax Renderey和PhaseListener 2种方式解决了系统中客户端响应速度慢的问题.该系统可有效提高信息采集和传输处理的实时性和准确性,增加三防灾害的预测精度.

Based on ArcGIS Server and JSF technology, a supportive information for decision making in the ＂three Web-based system has been developed to provide proofing projects＂ （wind proofing, drought proofing and flood proofing）. AjaxRenderer and PhaseListener have also been employed to settle the slow response of client. This system can efficiently improve the practicability and accuracy in information collection, processing and transmission, and hence can increase the accuracy in predicting the potential damages for the＂ three proofing projects＂.
