摘 要: | 本文研究了在GIS支持下的武汉东湖环境风险信息系统。运用GIS二次开发技术,在.NET平台下,使用C#语言和ArcEngine二次开发组件,采用三层C/S模式(用户界面一业务规则一数据服务)的逻辑架构,在环境数学模型的支持下,对数据采用GeoDataBase数据库方式进行管理。以武汉东湖为实例,进行了东湖风景区环境风险信息系统总体设计;重点对环境风险系统进行了详细设计,采用UML方法,使用Visio辅助建模,在进行用例分析基础上,对系统进行域类分析,分别得到模拟系统的用例图和域类图,并最终实现风险模拟的可视化。

Abstract: | The GIS-based Simulating System of Environmental Risk Information system are presented. It accomplished by applying secondary development technology of GIS,C# language and component secondary development of ArcEngine and design of logic structure with 3-tier C/S model (user Interface -Business Rule -Data Service) based on .NET platform,and managing the data through GeoDatabase,and which was supported by Mathematical Module of Environment. Taking Wuhan East Lake as a sample,firstly an overview design of Envi... |
