【摘要】 地理信息系统(GIS)是信息技术(IT)的一个重要组成部分,在信息社会中占有越来越重要的位置。传统的GIS软件不能完全满足GIS应用的需求,也不符合软件技术发展的潮流,在许多方面面临严峻的挑战。组件式GIS(ComGIS)是基于组件开发技术的新一代GIS,是解决传统GIS所面临的全新技术体系。本文在系统的研究组件式GIS的基础上,开发研制出基于组件技术的土地开发整理管理信息系统。 首先,本文讨论了GIS软件技术体系的发展、传统GIS面临的挑战、ComGIS的现状及发展趋势,提出了运用当今流行的组件技术,研制土地开发整理管理信息系统,来满足县级土地管理部门的土地开发整理业务工作需求。 其次,通过讨论ComGIS的有关技术,阐述与组件式软件技术相关的组件对象模型(COM)、分布式组件对象模型(DCOM)、对象连接与嵌入(OLE)和ActiveX等内容,并分析了这些技术在GIS中的应用。 然后,介绍了组件式GIS的相关内容,主要包括ComGIS的特点,组件式GIS程序设计与开发,以及国内外几种常用的一些组件式GIS工具软件,并对本文所采用的组件式GIS工具软件MapInfo MapX及其在土地开发整理管理信息系统中的应用作了介绍。 最后,介绍了笔者运用通用开发语言Visual Basic和组件式GIS工具软件MapInfo MapX集成二次开发出的土地开发整理管理信息系统,主要内容包括系统的设计目标、结构设计、功能设计、数据库设计,在研究系统的数据库设计时,对系统的空间数据库、属性数据库、文档数据库的设计作了较为详尽的阐述。并介绍了土地开发整理管理信息系统在江苏省江阴市国土管理局的应用。

【Abstract】 Geographic Information System (GIS) is a special field of Information Technologies (IT) . It plays a more and more important role in the information age we are now creating. Traditional GIS software can neither completely meet the demands of applications, nor keep pace with the mainstream of software technologies. Components GIS, briefly called ComGIS, is a new generation of GIS based on Components Software and Component-Based Development technologies. On the basis of the study on ComGIS ,the author develops the Land Develop and Arrange Management Information System(LDAMIS) based on component technologies.First of all , the essay discusses the development GIS software technologies ,the challenge which traditional GIS faces, the actuality and trends of ComGIS , and puts forward to use component-based development technologies to develop software so as to meet the demand of land managementIt is also noted that the essay expatiates software technologies concerning Components-Based Development which include Components Object Model (COM), Distributed Components Object Model (DCOM), Objects Linking and Embedding (OLE), as well as ActiveX, and analyzes the application of these technologies in GIS.Moreover, the essay introduces correlative content about ComGIS, which include the characteristic of ComGIS ,programmer and develop about ComGIS some ComGIS software tools inside and outside country , and a ComGIS software tool MapInfo MapXFinally, the essay introduces the Land Develop and Arrange Management Information System which integrate with Visual Basic and MapInfo MapX .The content includes design of object ,structure ,function and database . In addition, the author expatiates the design of special database and attribute database in detail ,and introduces the application of the Land Develop and Arrange Management Information System in JiangYing land management bureau in JiangSu province.
