Freis: A Web-based Resources and Environment Information System for Agro-ecosystem Management
Agro-ecosystem plays a crucial role in conserving biodiversity, sustaining ecosystem functions and processes, and maintaining land productive capacity. In order to effectively manage agro-ecosystem, the planners and government agencies are increasingly seeking better tools and techniques. In this paper, we describe the development of a Web-based resources and environment information system (FREIS), which helps to set up agricultural policy to improve productivity level and resource utility efficiency in terms of yield stability evaluation model. The system design involved four steps, the first was to set up a system platform for FREIS, then a spatial database was developed for analysis, after this the evaluation model was established, and lastly a Web-based interface with analysis tools was developed using client-server technology. FREIS provided a valuable technical scheme of the intelligent and comprehensive agricultural information management. The potential of a Webbased information system for agro-ecosystem management and challenges for its development was discussed.
