Spatial Analysis of the Distribution of Specialist Physicians' Offices in Mashhad

The spatial diffusion theory and its patterns (expansion, hierarchical, contagious, relocation) explain how phenomena disseminate from the origin of diffusion. By investigating pattern specialist physicians' offices in city Mashhad, present study showed that, contrary to common patterns, a new was formed by increasing number but not diffusing them at origin. This descriptive-analytical sample included all Mashhad (including 27 physicians 2425 offices). To this end, geographic database created according their type specialty addresses. Then, were identified using analysis models such as density profiles, mean center, standard distance. it examined each office diffused autocorrelation models, network analysis, location-allocation. Finally, rate determined scatter diagrams correlation coefficient. results indicated that distribution follows called "inverse diffusion". It is characterized high mobility origin, between absorption rates, non-diffusion resulted daily inflows outflows people area, low diversity land uses, isolation area other parts city.
