چکیده | ||
یکی از مهمترین مباحث شهر و شهرنشینی در ایران امروز، بررسی و تحلیل رشد و توسعة کالبدی-فضایی شهر و شهرنشینی است. در این زمینه، هدف کلی برنامهریزی شهری تأمین رفاه مردم از طریق ایجاد محیطی بهتر، سالمتر، آسانتر، مؤثرتر و دلپذیرتر است. بهاینترتیب، تحلیل تناسب زمین برای توسعة شهری و شناسایی اراضی مناسب و اولویتدار برای توسعة فضایی بسیار ضروری مینماید. هدف این پژوهش، تحلیل عوامل و شاخصهای کمی مؤثر بر رشد نامتعادل شهر خرمآباد است. نوع تحقیق کاربردی و روش اجرای آن توصیفی-تحلیلی است. در پژوهش حاضر، با بهرهگیری از مدلهای آنتروپی شانون و هلدرن، متغیرهای فضایی رشد نامتعادل خرمآباد تحلیل شده است. براساس یافتههای پژوهش در زمینة رشد نامتعادل در فاصلة سالهای 1368- 1390، حدود 24 درصد از این رشد مربوط به افزایش جمعیت و 76 درصد دیگر مربوط به رشد افقی و اسپرال است. طبق نتایج تحلیل یافتههای تحقیق، با توجه به گسترش شکاف ارزش آنتروپی ناشی از رشد افقی و اسپرال خرمآباد، که متأثر از الگوی رشد خطی آن است، الگوی قطاعی متمرکز الگوی مطلوب گسترش آتی آن تشخیص داده شد. بهمنظور تحقق این مسئلة مهم، باید با تقدم زمانی و مکانی از الگوی گسترش تمرکز درون بافتی و در عین حال الگوی پیوستة قطاعی با توسعة سیستم شبکة ارتباطی متقاطع و مورب بهره گرفت. در بخش پایانی تحقیق با تهیة لایههای اطلاعاتی قابلیت اراضی، سطوح ارتفاعی، شیب، شبکة ارتباطی، فرودگاه، گورستان، رودخانه، شهرک صنعتی و نقاط روستایی اطراف شهر اراضی مناسب بهمنظور توسعة آتی شهر درنظر گرفته شد. یافتههای پژوهش بیانگر مکانیابی توسعة آتی شهر به سمت جنوب خرمآباد است. | ||

چکیده [English] | ||
One of the most important discussions in urban and urbanization in current Iran is to determine and analyze the growth and physical- spatial improvement of urban and urbanization. In this relation the main objective of urban planning is to prepare residences welfare via establishment of better, healthier, easier, more efficient, and pleasant environment. To this end, suitable analysis of earth to improve urban and determining suitable fields and among the prioritiesfor spatial development is essential. To this end, the aim of presented research is to study the procedure of physical improvement of Khoramabad, identifying influent factors in urban spatial improvement, studying the sequences of city improvement and its physical paradigms, identifying the capacities and development limits of the city, providing solutions principles and action plan for the physical development of the city. A research method in this study has been of type analytical - descriptive. After historical development of the city, factors and constraints affecting the physical development of the city has been studied. Based on assumptions set forth in the study, the role of natural and human factors, the physical expansion of Khoramabad has been studied. The results show that the natural and human factors and barriers have a major role in direction of the city's physical development. At final part, preparing informational layers such as land capability, surface elevation, slope, land stability, communication networks, airports, cemeteries, rivers, industrial and rural areas and entrance of these layers to ArcGIS and their analyzing in geographical information system database, using AHP model and Expert Choice Software, suitable lands for future development of city were determined. These lands are mostly located at the south parts of city.One of the most important discussions in urban and urbanization in current Iran is to determine and analyze the growth and physical- spatial improvement of urban and urbanization.
