ON REGIONAL DIFFERENTIATION IN URBAN LAND USE VALUE AND MATHEMATICAL ANALYSIS ON GRADATION STUDY
关于城镇土地利用价值的地域差异与分等研究的数理分析

It is of great importance to the improvement of land use system to establish the urban land gradation guidance system and evaluating method.After probing further into statistical method on the urban land gradation study,this paper indicates that selection of of factors in the gredation system is very important.Though it is necessary to select as many factors as possible,the statistical work load rises greatly,and may concealle the role of important factor.The factor analysis method helps to select less representative factors as possible,so as to reduce the work load and seize the main contradiction.Also the paper puts forward suggestions based on the systematic study of the gradation method.
