Expert systems for pratacultural development in Gansu province

Expert systems for pratacultural development, based on 3S (RS: Remote Sensing, GIS: Geographic Information System, GPS: Global Positioning System) and internet technologies, can show users the knowledge and experiences, as well as the techniques accumulated by pratacultural specialists for many years using multimedia (e.g., text, graphics, imaginary and video information) methods. It has an important implication for directing ecological environment construction and pratacultural development in the western China because it can be dynamically renewed. In this paper, the total framework of Gansu expert systems for pratacultural development was systematically analyzed and designed. The basic contents of database, knowledge base and model base, and the major functions of this system, are discussed in detail in order to provide essential information to develop it in practice.
