چکیده
آخرین یافته های علمی موجود در حوزه پراکنده رویی شهری اغلب به گونه شناسی توجه کرده اند؛ ازاین رو در مقاله حاضر باهدف شناسایی انواع مختلفی از گونه های پراکنده رویی شهری در کلان شهر کرج سعی شده است دیدگاه های موجود در گونه شناسی، شاخص های شناسایی هرگونه و چگونگی طبقه بندی گونه های مختلف در کلان شهر کرج مورد بررسی قرار گیرد. محدوده مکانی پژوهش، مناطق 10گانه کلان شهر کرج بوده است. داده ها با استفاده از روش کتابخانه ای و میدانی جمع آوری شده است. نوع داده ها شامل داده های جمعیتی مرکز آمار و داده های مکان محور سازمان نقشه برداری کشور و شهرداری کرج بوده است. روش تجزیه وتحلیل داده ها به صورت کمی و با استفاده از تکنیک ضریب موران، تراکم کرنل، تحلیل چیدمان فضا، شاخص شکل و منطق بولین انجام شده است. نتایج حاصل حاکی از آن است که شهر کرج دچار رشد غیر سازمان یافته و بد قواره بوده و با گونه های مختلفی از پراکنده رویی شهری مواجه می باشد. گونه ی تراکم پایین و پیوسته پراکنده رویی شهری بیشترین حجم از مساحت شهر را در برگرفته است و عمدتاً در لبه های شهری کرج قرار دارد. هرچند گونه های دیگری ازجمله پراکنده رویی خطی یا نواری، پراکنده رویی جهشی یا گره گرهی نیز در این شهر وجود دارد؛ اما غلبه با گونه ی پراکنده رویی پیوسته با تراکم کم یا پراکنده رویی لبه ایی است؛ بنابراین می توان گفت پراکنده رویی در شهر کرج با یک شکل و الگوی واحد رشد و توسعه پیدا نکرده است؛ بلکه با اشکال و گونه های مختلف همراه بوده است.Explanation of the dispersion patterns of peri-urban areas of Karaj
Typology of dispersal in peri-urban areas of KarajAbstractThe latest scientific findings in the field of urban sprawl have often focused on typology; Therefore, in the present article, with the aim of identifying different types of scattered urban species in the metropolis of Karaj, an attempt has been made to examine the views on typology, identification criteria of each species and how to classify different species in the metropolis of Karaj. The research area was 10 areas of Karaj metropolis. Data were collected using library and field methods. The data type included demographic data of the Statistics Center and location-based data of the National Mapping Organization and Karaj Municipality. The data analysis method was performed quantitatively using Moran coefficient, kernel density, space arrangement analysis, shape index and Boolean logic. The results indicate that the city of Karaj is experiencing unorganized and ugly growth and is facing different types of urban dispersion. The type of low density and continuous scattering of urban sprawl covers the largest volume of the city area and is mainly located in the urban edges of Karaj. However, there are other types, such as linear or band scattering, jumping scattering, or nodal scattering; But dominance is a continuous, low-density scattering or edge scatter; Therefore, it can be said that dispersal in the city of Karaj has not developed with a single form and pattern; It has been associated with various forms and species.Keywords: Urban Sprawl, Sprawl Typology, Linear Sprawl, Low Density Growth, Discontinuous Physical Growth, Karaj Metropolis Typology of dispersal in peri-urban areas of KarajAbstractThe latest scientific findings in the field of urban sprawl have often focused on typology; Therefore, in the present article, with the aim of identifying different types of scattered urban species in the metropolis of Karaj, an attempt has been made to examine the views on typology, identification criteria of each species and how to classify different species in the metropolis of Karaj.
