Aims: This study examines the constituent elements of the spatial structure of Karaj metropolis and its relationship with the distribution of the population of this city. The main purpose of this study was to investigate the role of functional nuclei in the equilibrium or imbalance of the spatial structure of Karaj.
Methodology: The method of this research is descriptive-analytical and applied. The study area was the metropolis of Karaj and its 12 districts. The statistical population of the study was the population of Karaj metropolis. To analyze demographic data and activity dispersion, kernel density and spatial statistics methods including hot and cold spot analysis, general and local Moran analysis, and standard elliptic deviation analysis were used.
Findings: The research findings show that the population density is somewhat uniform and, in many areas, and neighborhoods of the city is clustered. While the pattern of dispersion of functional nuclei including administrative, recreational, commercial, public and industrial centers is random and is not dispersed in proportion to the distribution of the population.
Conclusion: The results of analyzing the different dimensions of the spatial structure of Karaj metropolis showed that the patterns of activity distribution are shifting from the centers of primary nuclei to busy and linear centers by changing the spatial relationships and the composition of uses changes in favor of functional nuclei (activity and service centers). has done. This factor has caused a lack of balanced and uniform distribution of urban facilities and services and has upset the balance of the spatial structure.
