Research Of Information Management System For Agricultural Mechanization Based On GIS

In November 2001, China entered into the World Trade Organization (WTO). Even though huge opportunities are expected to emerge from this long-waiting WTO agreement; it brings Chinese economy and people great challenges. We have to keep gross domestic product growing fast enough to provide a cushion against the shocks and dislocations that accession into the WTO may bring. Agriculture is the very Chinese industry that will be affected supremely after the accession, which makes the trading system turned from bilateral trading restriction to the multisided trading system to face directly to the vehement produce competition. So, government will change the agricultural policy. In the face of this change, the agricultural mechanization, which is closed to the development of agricultural product and economy, should change its direction, service fields and keystones in work.The management of agricultural mechanization information should be reinforced to exert the function of agricultural mechanization in the process of agricultural modernization. So, it is necessary to make the interrelated criterion and evaluating method to build an indices frame of agricultural mechanization to evaluate the development level of agricultural mechanization and to accelerate the development of agricultural modernization.In the 1st Chapter of this thesis, the history of agricultural mechanization and its status is reviewed; some problems in it and the development trend are unfolded, which make the task of this thesis clear. And the content of this research is arranged on basis of this introduce.In the 2nd chapter, an existing method valuing the development of agricultural mechanization is introduced, based on which the Rough Set theory and ANN technology are expounded. A new model to evaluate the development of agricultural mechanization based on RS and ANN is put forward in this chapter; and it is proved that the new model has the same effect with the existing method but less indices so that it is easy to get data.In the 3rd chapter, the history, constitutes, principle of GIS and its function is introduced, and some technology GIS related is briefly presented. After discussing the importance of GIS technology to the development of agricultural mechanization, the fields, in which GIS technology could be used, in the management of agricultural mechanization information is put forward, and the subject of this thesis is brought forward.In the 4th chapter, the program interface of the MapObjects of ESRI is introduced in detail, and the method, with which we can apply GIS to an agricultural mechanization information management system, is presented and practised.In the 5th chapter, utilizing the agricultural mechanization data of Zhejiang province, we fulfill an agricultural mechanization information system grounded on GIS technology. It proves the-basic GIS functions of the system and gives a new approach to the management of agricultural mechanization information.In the 6th chapter, we discuss some functions and the outcome of the agricultural mechanization information system to open out its strong points.Finally, the 7th chapter summarizes the main contributes of our work, those work under improvement and the future work we could do to ameliorate the system.
