Indiscriminate and scattered expansion of the city, increase in the costs of urban services, increase in the use of new land are among these problems. However, most of the time there is space for development within the city boundaries and one of the suitable options for development is to use the intermediate development approach,which should be considered in big cities. Therefore, in this study, whit using an analytical-descriptive method, development potentials and important indicators of infill development in Qazvin city are determined. For this purpose, by collecting the views of a sample of people living in this city and urban management specialists, with using the hierarchical method of AHP, the weight and prioritization of the important criteria of infill development were determined and then in GIS software the weights obtained from the Dimtel method are multiplied in the layers, and finally, the layers are overlapped by using Fuzzy Overlay Gamma, and the final map is obtained, which determines the capacity of infill development of Qazvin city. The results showed that the variables of management and economic group are in the weakest condition in the target neighborhoods in Qazvin. According to experts' opinions, among the 13 important criteria for feasibility study of the development of Qazvin city, 3 building quality criteria such as floor of building( with 0.229), age of building(with 0.186) and slope( with 0.150) had the greatest impact on land suitability for Qazvin's infill development. Another results showed that the detailed zoning map of Qazvin city shows that out of the total 64132000 square meters of Qazvin lands, 6.57% of the lands are completely suitable for infill development, 15.45% of the suitable lands, 26.21% somewhat unsuitable, 31.19% unsuitable And 19% is completely inappropriate.The amount of development of the city in the next 5 years was determined to be 1,411,000 square meters. Also, the amount of land that can be considered as reserve land was estimated to be around 3924000. Therefore, based on the findings of the research, Qazvin city has a good potential for infill development and using sustainable urban growth benefits. Manuscript profile
