| Back ground of the study task: A Study on Integration of 慔igh yield & Benefit and Good Grain Quality of Modeled Cultivation of Foodstuff Crop (Rice) and Its Consultation System? which is ordered by The Science & Technology Department of Guangxi Autonomous Region, afler the systems analysis of rice production, the conception of Rice Production System and its characteristic have been defined and discussed in this paper. Based on it, Guided by Dialectical Materialism, systems theory and national agriculture modernization construction policy, and with the application of the method of system engineering ,confirming seriously to the law of market economy and the disciplines of integrity~ structure, time-dependence, harmony and other characteristics of systems, relationship of the discipline of rice growth and its environment have been studied. Aiming at the need of construction of on-yield-field?in Guangxi, the development of national rice growth, the excel development of agriculture and the diathesis of agricultural technicians of grass roots and peasants, the goal of system development and the method and technique for obtaining the goal have been determined scientifically and an innovative study on the software of Rice Cultivation Simulationptimization Decision Making and Consultation System Based on Expert System and Resource Management Information System(ERRCSODCS) has been conducted. Guided by the discipline of software engineering, and with the application of integration several subjects, collaboration of information experts and agronomist, integration of Resource Management Information System (RMIS), agriculture Expert System (ES) and Rice Cultivation Simulationptimization Decision Making and Consultation System (RCSODCS), integration of several new advanced cultivation techniques i such as seedling breeding on dry field, seedling casting, chemical control, pest (disease, pest, grass and rat) control and integration of macroscopic methods to microscopic methods as well as from qualitative methods to quantitative methods, the software ERRCSODCS has been developed. Owing to multimedia technique, the interface has been intellectualized highly; Integrated with some special subprograms, the data system which is based on relation model has some characteristics of Object桹riented technique; RMIS can manage not only space data and attribute data but also support information consultation and decision making consultation efficiently; With the integration of the traditional expert system based on rules and expert based on neural net, the system can learn by itself very well. In virtue of the integration of ES, RMIS and RCSODCS, not only the shortcomings of traditional simulation model technique, which can not solve the space information and fhzzy gray, uncertain, random, experiential problems efficiently has been solved, but also et problem?of the knowledge obtaining of traditional expert system has been solved, so that the software can be improved and perfected automatically. Thus ERRCSODCS is a new kind of agriculture information technique, and the experiment of study on computer simulationptimization project of II You7lS good grain & high yield in Nanning has been conducted successfully.
