The land-use changes and urban development are among the fundamental topics of spatial planning. Monitoring changes in previous years and predicting these changes in the coming years have a significant role in planning and organizing urban spaces. The purpose of this study was to investigate land-use change and urban development in Ahvaz with a landscaping approach based on balanced urban development. .Images of TM (1989), ETM+ (2002), and OLI (2019) of the Landsat satellite are the basis for analyzing this trend. LCM model was used to identify the past changes, while CA-Markov chain model was applied to predict the future changes. These images were classified using a support vector machine algorithm of the object-oriented method, and the land-use maps were prepared using three sensors with four classes of vegetation, barren areas, constructed areas, and water zones. The accuracy of maps was improved separately using NDVI and SAVI indexes in the classification of the images. The efficiency of the indexes was measure by kappa coefficients and the overall accuracy of land-use maps, and then changes were investigated using maps related to the superior index. The results showed that maps related to the SAVI index were more accurate and accordingly, they were used in assessing land-use changes. The LCM model showed that in the periods 1989-2002 and 2002-2019, 2602.92 hectares and 31174.77 hectares were added to the built areas, respectively. In both periods, the most changes were about converting barren lands to built-up areas and the least changes were related to the transformation of the built-up areas to water areas. The results of the CA-Markov model until 2029 showed the continuity of the increasing trend of built-up areas, such that in ten years, 2238.82 hectares will be added to the built-up areas, and it is anticipated that the area will reach approximately 12345.63 hectares by 2029.

مقدمه: کاربری اراضی شهرری در دهههای اخیر در زمینة شهرنشینی رشدی بیسابقه داشته است. تغییرات کاربری اراضی بر شرایط اجتماعی، اقتصادی، و محیط زیست تأثیر میگذارد. گردآوری اطلاعات دربارة این تغییرات برای برنامهریزی و مدیریت بهتر نواحی شهری در توسعة پایدار ضروری است. هدف: از این رو، هدف این مقاله این است که برای بررسی بهتر تغییرات کاربری تحت تأثیر توسعه در شهرری و همچنین بررسی یکپارچگی سیمای شهری از شاخص «تکهتکهشدگی» طی سالهای 1367 تا 1397 استفاده شود. سپس، راهکارهایی بر اساس معیارهای مناسب در جهت تعیین نقاط حساس ارائه شود. روش: با کمک تصاویر ماهوارة لندست چهار کاربری شهری و مسکونی، زمینهای کشاورزی، فضای سبز، و زمینهای بایر استخراج و میزان تغییرات کاربری اراضی مشخص شد. برای بررسی تکهتکهشدگی سیمای شهرری از سنجههای تعداد لکه، تراکم لکه، و بزرگترین لکه استفاده شد. در بخشی از مطالعه از کراس تب نیز استفاده شد. یافتهها: یافتهها نشان داد مساحت کاربری اراضی ساختهشدة شهری و فضای سبز شهری به ترتیب 7/369 و 6/55 هکتار افزایش و زمینهای کشاورزی و زمینهای بایر به ترتیب 8/213 و 5/211 هکتار کاهش داشته است. در کاربری شهری یکپارچگی افزایش یافته است. در کاربری فضای سبز و کشاورزی، به دلیل ایجاد و احداث جادهها، تکهتکهشدگی افزایش داشته است. نتیجه: در ادامه بر اساس معیارهای «فاصله از مرز»، «فاصله از راهها»، «مساحت لکهها»، و «اندازة لکهها» راهکارهایی برای تعیین نقاط حساس و شکنندة پوشش گیاهی و مسکونی ارائه شد تا برای بهبود وضعیت آنها برنامهریزی شود. زیرا تغییر کاربری، بهویژه از بین رفتن پوشش گیاهی، بر سیمای سرزمین تأثیر منفی میگذارد.

The authors introduce a new map of Britain, which is based on the city region concept and designed specifically to present data from the 1981 census. The primary purposes of this article are "to describe the main problems and distortions which result from using current administrative areas, outline the key features of the new way of defining British cities, and demonstrate the value of the new geographical framework with some basic statistics on city size and population trends."
