Study On Agricultural Information Service System In China

Stepping into 21^st century, information technology has been the important resource in the modern scientific and technology competition. Using information technology in the fields of agriculture also has become the necessary way for all countries to heighten the agricultural integrated competence in the world. So the tide of agricultural informatization is increasingly rising. Agricultural information service system is the strategic resource element in the course of informatization. It can provide all kinds of service safeguard that include technology. Agricultural information service system in our country has formed a rudiment. Many areas have made much progress. All levels of governments have bring the ways of forming agricultural information service system into the strategy planning when designing the middle and long-term developing strategy.But agricultural information service system in our country is not perfect yet, and has many problems. For example, the absence of main body's structure's integrity, service functions' definitude and service artifices' multiplicity. Based on our country's agricultural information service system developing survey and literature's gathering, the paper study the structure, function, running fashions, running mechanism and safeguard measures using systems analysis, optimizing method and estimation method.(1) Adopting time sequence analysis and agricultural informatization index, the paper measure and forecast the relationship between our country's agricultural informatization and agriculture economy's increase.(2) Using systematical analysis and comparing and inducing method, the paper discusses the conception and attributes of agricultural information service.(3) We give the construction of agricultural information service, and set up the whole framework from the two levels of country and locality.(4) The structure and function's optimization model of agricultural information service system is established using optimization without restrict and fuzzy neural network. Then the running fashions and mechanism is discussed by the way of trust-agent model and cost-benefit analysis. In the mean time, we adopt spot check and statistic to evaluate the running effect.(5) We take an example of Beijing agricultural information service system to give a demonstration analysis using relative methods.(6) Finally we discuss the developing stress and agricultural information service's benefits, and give the suggestions.
