The Integration Development And Realization Of The Land Resource Management Information System

Along with the advancement of technology, human are changing all aspects of environment at unprecedented speed The change of the utilizing land resource make the style of utilizing land resource change with each passing day For the land manager, as the traditional mode of manage can not adapt the change of utilizing land resource, they need a sort of land resource management information system which can update graph and data at real timeoThe appearance and development of "3S" (remote sensing globe position system geography information system)technology improve the change from traditional map to digital map, and offer the platform on which the land resource management information system can be developed which can satisfy the manager's requirement, and make it possible that develop the land resource management information system by the manner of system integration The article set forth the method and technology of developing the land resource management information system from the aspects of the manner of development the instruments of integrated development the design of system the data's organization the technology of integrated development.The manner of development: by comparing of the independence development and the second development, the author draw the conclusion that the second integrated development took full advantage of the function of GIS software as a tool and the application system developed through the second integrated development has fine performance and stability,) So the author put forward a model of using the second integrated development which candevelop the land resource management information system.The tools of integrated development: this article introduce MapInfo and Delphi which are used as the tools of development, and analyze their characteristics and function.The design of system: the author works out seven modules of this system according to the require of managing the land resource and introduces the function of each modules of the system.The organization of data: first, the author introduced the data structure of Maplnfo and studied file structures of the data and the mechanism of connection (especially the connection of graph&data). Then, the author works out the model of the data's structure of this system and set up database of classifying land that based on the model of relational database.The technology of integrated development: first, the author introduces some conceptions of the technology of object-oriented which related the development of this system and especially studies technology of OLE. At last, the author carry out the second integration development of the land resource management information system using the technology of OLE.Application instance: At this department, the author introduces some function of the system in the two instances.The integrated development has not only utilized the powerful function of graph management of GIS platform and the advantage of classical program language. Then, the integrated development assure not only the stability and reliability of the system but also well UI and management function of the system. Thus , the system can adapt the require of the management of the land resource. Furthermore, the integrated development provide a new thought about developing other software relation with the management of land resource. The author take a useful attempt at this development.
