چکیده

در کشور ایران نیز همانند کشورهای درحال‌توسعه، تمرکز بیش‌ازحد سرمایه‌های ملی و فرصت‌های شغلی باعث افزایش جاذبه‌های شهری و بروز مهاجرت‌های بزرگ از روستاها، شهرهای کوچک و متوسط به مراکز سیاسی و منطقه‌ای شده است که موجب ایجاد پدیده نخست شهری و افزایش تعداد شهرها گردیده است. با توجه به اهمیت موضوع، تحقیق حاضر باهدف ارزیابی و تحلیل سیستم شهری استان چهارمحال و بختیاری طی دوره 1956 الی 2016 صورت پذیرفته است. روش تحقیق بر اساس هدف کاربردی با ماهیت توصیفی- تحلیلی است. جامعه آماری تحقیق تمام 40 سکونتگاه شهری استان چهارمحال و بختیاری طی دوره 1956 تا 2016 می‌باشد. شاخص‌های به‌کاررفته در تحقیق مشتمل بر نخست شهری، تمرکز شهری، توزیع متعادل و الگوی پراکنش سکونتگاه‌های شهری می‌باشد. در مجموع، نتایج شاخص‌های ارزیابی نخست شهری نشان می‌دهند که سیستم شهری استان چهارمحال و بختیاری طی دوره 2016-1956 به سمت عدم تعادل و تسلط نخست شهری در حرکت می‌باشد. نتایج شاخص تمرکز هرفیندال نشان می‌دهد که میزان تمرکز در سیستم شهری استان از سال 1956 تا سال 2016 روند کاهشی داشته و به سمت تعادل در حرکت می‌باشد. نتایج مدل حد اختلاف طبقه‌ای حاکی از ایجاد اختلاف در طبقات جمعیتی شهرها درگذر زمان و فاصله گرفتن شهر اول استان از شهر دوم و سایر شهرها است. نتایج ضریب آنتروپی بیانگر متعادل شدن توزیع فضایی جمعیت در سیستم شهری استان چهارمحال و بختیاری است. نتیجه تحلیل نزدیک‌ترین همسایگی نیز بیانگر الگوی تقریبا یکنواخت توزیع سکونتگاه‌های استان است.

The results of the class difference method indicate the difference in the population classes of cities over time and increase the distance of the first city of the province from the second city and other cities.
