چکیده
با افزایش سریع جمعیت شهرنشین، تحولات مربوط به کالبد و فضاهای شهری شتاب‌آلود می‌شود. این تحولات منجر به پیدایش رشد افقی، تغییر کاربری، تخریب و انهدام فضاهای سبز، باغات و اراضی کشاورزی در اطراف شهر و بروز پدیده خزش شهری و در نهایت رشد بی‌قواره شهری می‌شود. پدیده خزش شهری، به عنوان یکی از مسائل جدی شهرهای در حال توسعه، باعث گسترش ناموزون و پراکنده‌شهری می‌شود. پژوهش حاضر به لحاظ هدف، کاربردی و به لحاظ روش انجام، توصیفی – تحلیلی است. این پژوهش با بهره‌گیری از تکنیک‌های سنجش از دور و سیستم اطلاعات جغرافیایی، به بررسی و تحلیل روند خزش شهری کرمان طی سه دوره زمانی 2000، 2013 و 2023 پرداخته است.  به دلیل محاسبه رشد شتابان شهر کرمان با استفاده از تصاویر ماهواره ­ی لندست 7 و 8 طی دوره ­های مورد بررسی، نتایج نشان داد که این شهر در همه جهات به صورت پراکنده رشد داشته؛ اما بیش­تر میزان این رشد به سمت شرق و جنوب شهر کرمان در امتداد مسیرهای اصلی ورودی و خروجی شهر صورت گرفته است. هم­چنین رشد توسعه شهری طی دوره­ های مطالعاتی افزایش یافته و در دوره مطالعاتی 2023 رشد شهری بیش­تری نسبت به سال 2013 رخ داده است. همچنین با استفاده از مدل‌های مختلف تحلیل، دقت بالای یافته‌ها تایید شده و پیامدهای اقتصادی و زیست‌محیطی این گسترش شناسایی شده است.

Extended Abstract
Introduction:
With the rapid increase of the urban population, the changes related to the body and urban spaces are accelerating; These developments lead to the emergence of horizontal growth, change of use, destruction and destruction of green spaces, gardens and agricultural lands around the city, and the phenomenon of urban creep and ultimately urban growth.
Materials and methods:
In the current research, which is practical in terms of its purpose and descriptive-analytical in terms of its method; In order to calculate the rapid growth of Kerman city, Landsat 7 and 8 satellite images during the periods of 2000, 2013 and 2023 and their analysis in ENVI software were used.
Results and Discussion:
The first period (year 2000): The results of the surveys showed that Kerman city had 5319 hectares of physical urban growth in 2000, but this physical growth shows the direction of the urban growth pattern towards the east and parts of it. It is from the southeast.
The second period (year 2013): The results of the surveys showed that after 13 years, the city of Kerman has increased by 2508 hectares to the amount of 7827 hectares.
The third period (year 2023): The results of the surveys showed that after 10 years, the city of Kerman has increased by 3464 hectares to the amount of 11291 hectares.
Conclusion:
The results showed that the city of Kerman has grown sporadically in all directions. But most of this growth has taken place towards the east and south of Kerman along the main entrance and exit routes of the city. Also, the growth of urban development has increased during the study periods and the study period of 2023 has shown more urban growth compared to 2013.
