three construct model

The analysis of social areas describes the mechanism by which households select or are assigned specific residential areas within the city. This mechanism is not definitive and there is no clear plan related to it. For this purpose, for the analysis of social areas, it is necessary to use a method that solves the different spatial complexities within and between departments. In the meantime, the model of three constructions is considered as one of the comprehensive and integrated methods in the analysis of social areas, which separates or differentiates social areas based on three factors: socio-economic status, housing and household status, and segregation or racial discrimination. For this reason, in the current research, using the descriptive-analytical method and the three-structure model, firstly, it determined the criteria that can be used in determining the social areas in the seventh district of Isfahan city as the case study of this research, and then, based on the overlapping map technique, the resulting maps of criteria have been combined and finally, the social areas of 7th district of Isfahan have been depicted in a map based on the analyzes carried out.

The expansion of urbanization and changes in the way of life in the 20th century have made citizens face many problems. Based on this, finding suitable solutions to analyze problems can play an important role in the continuation of the city's dynamism and development. District 7 of Isfahan, as one of the districts of this metropolis, is facing serious problems in its spatial and activity structure, which has led to dissatisfaction and migration of local residents. Based on this, identifying the problems of the spatial and activity structure of the region based on the problem-finding-problem-solving approach is considered as the main goal of this article, and it is obtained from 4 paths of spatial structure analysis, analysis of extraterritorial programs, social audits and interviews with officials. In this regard, the current research was carried out with a descriptive-analytical method and collected the required data with a library-field method. The data related to the theoretical foundations and identification of problems in the documents are collected by the library method and the data of spatial and activity structure problems by the field method and the completion of 139 questionnaires among the residents and conducting 10 interviews with the officials.
