Application Of BP Neural Network To Valuation Of Standard Land Price And Net Distribution Of Achievements

The evaluation of standard land price as one of the primary means for macroscopical control plays a important role in regulating real estate market, maintaining country's regular income and town development. With the quick development of economy urbanization, land price rise constantly. Standard land price should be continuously updated to ensure its reality. The general methods of standard land price evaluation is relatively complicated and need investigation data. Since neural network has the merits of nonlinear mapping, great tolerance, high veracity of prediction results and quick prediction etc, it is introduced to evaluation of standard land price to explore a method to evaluate standard land price in a relatively simple, practical and accurate way. Through the case research of standard land price evaluation method in the center city business region, it shows that the method is economic, convenient and of the ability of strong adaptation.To make the research production used widely, standard land price database and graph database building has been accomplished by taking advantage of advanced network techniques combined with GIS techniques. In the same time, a public platform has been constructed to realize share of data on Internet and two-way communication between management department and the public. One hand, the public can get price information through the platform, On the other hand, management department acquire the public's feedback information about the land price application as reference warranty for adjustation of standard land price.
