The Design,Realization And Application Of The Investigation System Of Cultivated Land Resources

Cultivated land resources is an important base for the implementation of land management. It’s a import guarantee to realize the balance of occupation. Improvement of land and resources with the scientific method can ensure food security and economic development. So we need to fully grasp the situation of cultivated land resources.In agriculture, land resources, environment and other aspects, The application of GIS technology is very broad. Component technology brings a revolution, it’s also a highter opportunities. The GIS function module is divided into several control based with COM. Every part perform different functions. Every control can be integrated through the visual development tools of IDE, the formation of final GIS application has the incomparable advantage of many of the traditional development tools.This paper designed the reserve resources database system according to the cultivated land resources evaluation database design standard. The goal is to Improve the work efficiency. This paper is designed in detail from three levels of the system. Include of the data layer, logic layer, presentation layer. The system not only has the common functions of GIS basic, also have a batch of automatic evaluation,index system of evaluation of the manual. The evaluation questionnaire into attribute field fill, data statistics, spatial statistics and other functions. The basic function to meet the needs of the user database.Finally, In the case of Wudu District of Longnan City, The results show that, the system has the advantages of simple operation, strong expansibility, adapt to the investigation of the reserve resources of cultivated land evaluation units at the county level. Finally, The system completed the work of database and dada analysis.
