Permanent Basic Farmland Demarcated System Design And Implementation Of Jiangxi Province

The economic growth is accelerating after the reform and development of our conutry, rural areas are constantly urbanization and industrialization, urban construction land area is growing, farming land and urban and industrial development in the space generated by friction, these are made less and less agricultural land. At the same time the quality of industrial chemical pollution of land and the destruction of the environment surrounding land, affecting the ecological balance and natural resources. For these reasons the safety of food production in the country had a great threat. Basic farmland permanently designated for ensuring food security, alleviate the food crisis, to ensure ecological safety, ensure quality arable land and promote sustainable economic development is of great significance.This study is based mainly on the second national land survey land units to provide data software applications, maps,cities and counties in Jiangxi land use planning as well as the "basic farmland designated Technical Specification" and other information, MapGis use software platform to build a relational database of basic farmland, And the use of object-oriented visual programming language C ++ in software VC ++ 6.0, design and realization of basic farmland permanently designated system of Jiangxi Province. The first part introduces the purpose, the background and significance of this research background, conditions on arable land protection plan is reviewed and abroad, a clear objective of this study and the main content. The second part reviewed the secondary development of basic farmland designated and MapGis of new construction land use classification and system development. The third section describes the system of outline design. First introduced in order to understand the technical principles of technical specification of this system design, technical processes and technologies critical. Finally, analysis of the design of the system architecture, an overview of the function modules and database design system. Part IV presents a detailed analysis of the design and implementation of the system, this part is the core of this article,a detailed description of the application of this system is the process of basic farmland demarcated- To extract data, according to data produced underlay, underlay set rules based on the analysis results transferred in and out of land plots, then the basic farmland designated base map and "Recall Lot"(TCDK.WP), "transferred land"(TRDK.WP) conducted a two-way analysis of land zoned land to get early.Finally, after adjustment of basic farmland plots to get the final piece of basic farmland protection. Section V describes the basic farmland protection sheet delineated, property storage and output modules for achieving results. Mount basic farmland protection blocks need to be consolidated after the delimitation of basic farmland protection sheet and generate it for attributes such as the number and area, then you can output images and tables according to the database. The sixth part in the system design is completed each module programming process of software testing and maintenance of the system in order to guarantee the long-term running smoothly. Part VII summarizes the content and innovation culture, and proposed the deficiencies and improvement points in this paper.The most important thing is to work for a permanent basic farmland designated Jiangxi Province, then according to the actual situation of Jiangxi corresponding protection of basic farmland. During the design and implementation of the system to testing and debugging software, human-computer interaction achieve permanent basic farmland designated work, to ensure that the number of basic farmland, enhance the quality of basic farmland, establish and improve the management of the new situation of land resources.
