The Study And Implement Of Land Use Dynamic Management System

The Land use information management of our country has no systemic and whole description. Though many kinds of software for land use is being explored, it can not be fulfillment the comprehensive use and valid management. Judging from the macroscopical and microcosmic angel, land in rural and city is managed straightforward, as a result, it causes so much waste in the management course.How to get data in time is also another problem because the illogical data access mechanism. In addition, there are some problems existing in the land information construction, for examples, the self-adaptation data management mechanism based on dynamic data model is not mature, intelligent report print mechanism is yet not deeply applied and the effective special methods is still not be adequately settled.The study aim of this paper is mainly to solve above problems in order to improve the work efficiency of the land use management, protect the farmland for sure and serve for digital land project. The software is developed out in the end so that it can fulfill the daily land operation, assistant leads decision-making and accomplish dynamic management.The primary study content consists data model study, data sources study, key technology study, decision-making study, information service study and dynamic management study.(1) Data model studyThe data model is get by analysis the work flows of land management department, data concept design, logical design, data coding and standardization. It includes the image and attribute information, city and rural, especially the dynamic change information in land use.(2) Data sources studyStudy data source based on looking the county as the basic data source, and manage the data multi-dimension and eliminate the data redundant problem.(3) Key technology studyThe key technology mostly includes self-adaptation data access technology, intelligent report print technology, spatial analysis technology, multi-dimension display technology and data management technology.(4) Decision-making studyStudy the land use management system which consists of land plan system, land develop and based on the multi-S integration technology, accomplish land use dynamic evolvement and decision-making.(5) Information service studyThe land data warehouse model is is the core in land use information system which is built based on the basic data model. The land information service can be realized, such as data query...
