Requisition Price Valuation Information Based On The Agricultural Land Grading Assessment Methods

The agricultural land evaluation is a comprehensive and complicated process referring to resources, economy, society, environment and statistic analyse. At present the agricultural land evaluation study is still in exploring step in domestic. The work about agricultural land evaluation is mainly referenced to the methodology and process of town land evaluation. Through long-term exploration and practice, the theories, methodologies and technology routes of agricultural land evaluation then formed. Presently, most of these information systems of classification and evaluation of agricultural land are behind the times in technology, lacking uniform standards and systematism. With the rapidly development of economy, the agricultural land evaluation becomes more and more complicated. It is obviously unscientific if we do research from only one aspect. So we should use multi-subject methodologies and technologies to support agricultural land evaluation, and make the evaluation of agricultural land price suitable to the development of economy and society nowadays. The development of database and GIS and the utility of them have provided technical support and experience to the combination of agricultural land evaluation and GIS. We can use database for data storage and express graphics with GIS. And more importantly we can realize and expand traditional theories and models of agricultural land evaluation through GIS.On the basis of explaining the relevant connotation of agricultural land expropriation price, the author analyses the background and significance of the agricultural land price evaluation, expatiates the design of agricultural land expropriation price evaluation methodology and accomplishes the construction of information system database on agricultural land price evaluation. At last, the author tests the system through Jiangsu Xinghua agricultural land price evaluation and achieves anticipative purpose.In Section A, the author analyses the background and significance of agricultural land expropriation price and expounds the meanings of basic definitions explicitly. Then, illustrates the dynamic research of agricultural land expropriation price in domestic. Finally, the author brings forward the thought of setting up the evaluation information system of agricultural land expropriation price.In Section B, on the basis of analyzing the compensation methodology and the feature of agricultural land expropriation, and comparing domestic experts' different views on the connotation of land expropriation price, the author confirmed the connotation of land expropriation price and ascertained the methodology and technology route of agricultural land evaluation according to the agricultural land evaluation regulations.In Section C, the author expatiates the design and exploration of the database system of agricultural land price, which consists of data collection, data process, data flow, data form and data structure, data dictionary, etc.In Section D, the author tests the application of the system, taking Jiangsu Xinghua agricultural land expropriation evaluation as an example.In Section E, the author draws his conclusions and puts forward corresponding suggestions on further study of computing the agricultural land expropriation price.In the dissertation, the author expounds his own opinions and combines theory with practice. Findings are as follows:1.Strictly following national regulations, designed and accomplished the agricultural land expropriation price database which bases on agricultural land classification and evaluation.2. Accomplished agricultural land expropriation price evaluation of Jiangsu Xinghua with this method, which sets a successful example of using advanced technology for agricultural land evaluation.
