The Research On The Grading Of The Urban Land In Xinjiang

The development degree of the urban economy is decided by the number of landuse resources, quality and position in great degree.The urban land is a complex system made up of nature, economy and social diversified factors and its quality and grading lie on the quality of every factor and their combining situation. The grating land is the process of comprehensive evaluation to the natural and economic attribution of the land and grating its result according to a given aim. It is a type of the evaluation of land , further more is a comprehensive evaluation to the quality of land. The rank of land reflects the difference of land quality and relating difference of land income among cities in one region. The grading urban land shows the section difference of land quality, classifies the urban land combining quantitative analysis and qualitative analysis and evaluates the urban land by comprehensive analyzing the economic , social, natural and section factors effecting the quality of urban land.The center content of this thesis is research on the grating the urban land including the 85 county in Xinjiang Province. This thesis includes 7 chapters. This research selects factors according to the demand of urban land grading and section otherness in research area and sets up factors system effecting urban-grade between cities; inputs the data which come from statistic including five factors (economy, section, infrastructure, the degree of urbanization, input and output of the urban) of the 85 counties in Xinjiang Province to computer, clears up the data and constructs the database of Xinjiang Urban Land Grading Factors by Microsoft Visual Foxpro; using for reference, applies Delphi to select factor, to ascertain their coefficient, to extremum standard original data and to extremum standard separate data using weeding way; adopts mathematics model for coefficient sum to calculate the integrate value of every urban; shows the assemble frequency curve of the integrate value and partition logical space to make sure of the urban land grading primarily.In succession, this thesis adopts systemic clustering to compare and validate the grading of the primary result. After clears up the original data, this research inputs them into the software SPSS and adopts Euclidean distance and Wardis Method to output the pedigree map of systemic clustering. Analyzing the evaluating result from the two different model, we can find the two results basic coherence. The author adjusts the individual grading of the urban using qualitative analysis and quantitative analysis because of existing deviation caused by the difference between modeling foundation and function and gains the assessed result of the grading of the urban land. Next, this research applies MAPGIS to mapping the grading of the urban in Xinjiang Province. For the demand of the result of the urban land grading, this research extract the corresponding map from the whole Xinjiang landuse electronic map. The constructing database of the attribution is the grading of all the counties in Xinjiang Province and can directly input the attribution data of the every speck in MAPGIS, and also can input in Visual Foxpro or Excel. We can link the graphics database with the attribution database of a certain character according to certain situation and MAPGIS offers the data access. So this research complete the land grading map.Then, this thesis discusses the development stratagem, the guide ideology and the development stratagem of Xinjiang Province.Finally, this thesis expatiates the relation of how to develop urban better, how to develop urban characteristic economy, support industry and analyzing individual main cities.
