A Study On The Creation And Application Of Land Resources And Environment Information System Based On GIS

According to theory and methods of System Engineering, this paper studied the information management of land resources and environment based on the Nanning Overseas Chinese Investment Zone Ecological Environment Construction. Guided by system theory, various Subject-intellectual Knowledge is comprehensively applied in the paper, such as information science, computer science and land resources management science. The structure and function of Land Resources and Environment Information System was designed by analyzing the object and mission of the system, the user's demand and the source of data. Then the concept and logic of the database was designed .After classifying the data and coding , a database including such data types as text, figures and tables was built. By using Object-Oriented and Controler-Oriented method, the Land Resources and Environment Information System Based on GIS was developed. In order to adopts to the demand of analyzing and expressing the space information in land use planning and ecological environment construction, a spatial analysis module was designed for the Land Resources and Environment Information System, which makes the system structure more reasonable and the service function more strengthened .The system has played an important role in the planning of ecological environment construction in Nanning Overseas Chinese Investment Zone.The merit of this paper is organically combination GIS with MIS. The combination makes it possible to solve the difficult problem which can not be solved by the traditional MIS. This paper offers an efficient tool for the management of land resources and environment information.
