The Town Land Classification And Price Evaluation Based On The GIS And The Grid Soil-rent Value Model Discussion And Analysis

The town land classification and price evaluation is an important constituent of the land resource management. Through the town land classification and datum soil-rent value renewal may guarantee the country land ownership in the economical realization as well as the use economical method strengthening land property management, may promote the land using system reform, paid sells, transfer state-owned land property rights, strengthen the country to the land market management, promote normal transaction, thus provide the basis for using the city land comprehensive, scientific, reasonably.This article depends on the town land classification and land price evaluation project of Hefei in 2007, first analyzes the domestic and foreign research present situation of this topic, discusses certain essential technologies related to the town land established grades, the datum soil-rent value renewal with the cities as well as the grid soil-rent value model analysis, including land appraisal theory, GIS technology, artificial neural network algorithm of BP and so on. In the town land classification, we discuss the work steps, the factor system establishment, the factor material reorganization and the quantification of the town land classification and so on, then using GIS software to carry on the detailed computation for the established grades, finally produce the achievement of the established grades. In the datum soil-rent value we emphatically discuss the common methods of the sample spot soil-rent value computation and the revision, carry on the solution and the analysis for the datum soil-rent value using the sample spot soil-rent mean value and the factor comparison test. The grid soil-rent value is the innovation spot of this article, also is the content which this article emphatically discusses, expatiate the grid soil-rent value concept, the characteristic and the significance, and carry on the grid soil-rent value which has surveyed with the analysis using the return model and the nerve network BP model. Finally summarize this paper, and put forward certain following research proposals...
