摘要

Floods occur frequently in Poyang lake area, and damage caused by floods are enormous every year. In order to get hold of the damage timely and accurately and minimize the loss, this paper analyzes the general situations of Poyang lake area, then uses the Silverlight as RIA client display technique to design and implement the flood control geographic information release system in Poyang lake area. This system implements many functions, such as basic map navigation, geographic reports, basic work situations, social economic data query, statistics and analyzing, flood prediction information release, flood damage assessment data management and the feedback of users' information and so on. In the aspect of flood control and disaster relief this system offers decision-supporting services for the government and the flood prevention department to get hold of the situation of flood and loss timely, accurately and entirety.%鄱阳湖地区洪涝频发，每年因此造成的损失十分巨大，为了及时准确地掌握灾情，使损失降到最低，文中在分析了湖区概况的基础上，采用Silverlight RIA客户端呈现技术设计并实现了鄱阳湖地区防汛抗洪地理信息发布系统。系统实现基本的地图导航、地理报表等功能外，还包括基础工情管理，社会经济数据的查询、统计和分析，洪水预报信息的发布，洪灾损失评估数据管理以及用户反馈信息的采集等功能，为洪泛区各级政府和防汛部门及时、准确、全面地掌握洪涝灾害及损失情况提供防汛和救灾的决策支持服务。
