A comparative analysis on the results of different methods in assessment land use mix in Mashhad

In recent years, land use mix has become an important issue of ​​research in urban studies. One of the important issues related to land use mix is how to measure it in urban areas. Given that many studies have assumed land use mix as an independent variable affecting other urban life dimensions, Therefore, how it is measured is crucial for achieving reliable results. The purpose of this research was to evaluate the results of different methods in assessment land use mix of Mashhad. The research method is an analytical-comparative approach and the data has been collected through land use documentation of Mashhad and we use Frank, Herfindahl-Hirschman, and Simpson and Shannon entropy methods for measure land use mix. The results showed that the four methods used in this study can be classified into two categories based on similarity in results. The entropy Shannon and Frank methods are in the same class and the Simpson and Herfindahl-Hirschman methods are in the same class. Surveys showed that the type of method used to measure land use mix can influence the results obtained and therefore, it is necessary to consider land use mix, especially when it is to be used as an important independent variable in research, the type of method must be carefully and obsessively selected or two or more different methods were used to assess land use mix. We cannot provide a reliable answer as to which of the four methods used in this study is more reliable and Accordingly, it is suggested that weighting of different land uses based on its importance in measuring land use mix, based on the nature of the subject under consideration.
