Investigation of physical development of Khorram Abad city with emphasis on indigenous development indicators

endogenous development, the goal is not only the development of the city from inner parts, rather the quality of putting different land uses together and integrating them next to each other is a matter for planners. In this regard, the present study has considered the physical development characteristics of Khorram Abad city in terms of quality of physical development of the city by using indicators such as land use compatibility and incompatibility, land use mixture index as well as quantitative indices determining he indigenous development of city such as population density changes, the ratio of area growth to population, the number of licenses issued, and the quality and age of buildings in old texture. The research method is descriptive-analytical through library (documentary) and field studies. The results of this study show that, despite the fact that the city of Khorram Abad has internal development potentials, but like other cities in our country, it has experienced sprawl growth in recent decades. Investigation of various indicators showed that the city did not follow the indigenous development policy in its physical-spatial development. In addition, less attention has been paid to the compatibility and incompatibility of neighboring land uses and to the mixing of different land uses within the urban context. Considering the developmental capacities in the old textures of Khorram Abad city, construction in these textures, by implementing incentives policies and increasing floor area ratio, is the best way to prevent uncontrolled growth of the city, reduce costs and urban development issues
