基于组件式GIS的黄河流域水土保持信息系统的设计与实现

Development and realization of soil and water conservation information system for Yellow River based on component GIS technology

【目的】构建黄河流域水土保持信息系统,为水土保持数据管理提供信息平台和科学依据。【方法】探讨了组件式GIS的概念,基于ArcObjects的GIS组件式二次开发的方法、关键技术和开发方式,并结合面向对象的运行于.NET Framework之上的C#语言,开发黄河流域水土保持信息系统。【结果】该系统既实现了GIS的基本功能,又实现了图像、文档、表格的查询、显示以及一定的图形编辑操作和多种选择的图形输出等功能。【结论】开发的黄河流域水土保持信息系统基本满足了水土保持工作对数据管理、分析的需求,为水土保持决策、规划、治理提供了科学的依据。

【Objective】 The soil and water conservation information system of the Yellow River has provided an information platform and scientific proof for data management.【Method】 The concept,ArcObjects Re-development method,essential technology and development of component GIS were discussed in this paper.A soil and water conservation for Yellow River level information system was developed based on the combination of GIS and programming tools C#,which is used in.NET Framework.【Result】 The system has some functions such as the basic function of GIS;image,data management,file management display and edition in database and the choices of image output.【Conclusion】 The successful development of this system can meet the basic needs of data manage and analyse,which provides scientist proof for decision-making,planning and management on soil and water conservation.
