Low Pass Filtering Model Apply In Urban Land Graduation Verified

With the development of our country’s economy, the deepening of the reform of non-gratuitous use system in china, Land grading system is of great significance. In the initial partition of land level after, The need for inspection by a certain method to divide the land level, To Verify whether reasonable division of land level, So it is necessary to conduct in-depth research on the level of test method and discussion.This article based on Land value theory, location theory and rental theory, From the theoretical and Empirical Analysis on urban land gradation and level check is studied.First, The urban land grading understanding of historical evolution was explained, discussed the nature of urban land classification.Second, Taking Lengshuijiang city as an example, by means of the demarcation of its commercial use land level multi factor comprehensive evaluation method, determining the research sample of this study. Finally, according to the related theory knowledge price grade method and filtering technology, taking Lengshuijiang Commercial land grading results as an example. Application of process method and Application Research of low-pass filter model in urban land level verified. Think that the low pass filter method to draw the curve of the easy to grasp space city land price change trend from the macro level, And can accurately determined from the micro level land level boundaries, The spatial resolution and space with high directivity, Check method is simple and easy to operate, Conclusion the results to determine the calibration of city land grading is reasonable or not has a high reference value.
