Abstract
The evaluation process of traditional land productivity is relatively complex, and the evaluation indices and results cannot display visually. With the development of geographic information system science, there are more and more studies on the GIS-based land productivity evaluation. GIS system can combine the evaluation model with information system software, realizing the visual display of all the evaluation factors. In this paper, with the development process of GIS-based management information system as references, the management information system for GIS-based gravel-mulched field productivity evaluation was designed and developed by combining with the SI model for gravel-mulched field productivity evaluation. The system was developed under VB environment, integrated with MapInfo, and the evaluation results could be shown visually in the system windows.
