ملخص المقالة :

سکونت گاه های انسانی همواره آسیب های جبران ناپذیری ناشی از وقوع مخاطرات طبیعی به خصوص زلزله می پذیرند در این باره در راستای کاهش اثرات زلزله به عنوان قلب مخرب بافت های فرسوده شهری، توجه به رویکرد تاب آوری به عنوان الگویی جهت کاهش آسیب و افزایش راندمان افراد و ساختمان های موجود در سطح این بازه از بافت ها ارائه می گردد. در این پژوهش به دنبال ارزیابی تاب آوری کالبدی شهر جهرم در برابر خطر زلزله با هدف شناسایی بافت های فرسوده در این شهر هستیم که با رویکردی توصیفی - تحلیلی ، مبتنی بر مطالعات کتابخانه ای و بررسی های میدانی ، سعی دارد تا آسیب های ناشی از وقوع این فرآیند را بررسی و تحلیل نماید. در این بین برای بررسی وضعیت تاب آوری شهر جهرم با هدف شناسایی بافت های فرسوده از روش (Hot Spot ) از ابزار cluster & outlier analysis از مجموعه ابزار‌های موجود در Spatial Statistics Tools مربوط به نرم افزار ArcGIS استفاده شده است. نتایج این پژوهش نشان می‌دهدکه: 200696 متر مربع یعنی 19/77 درصد از مساحت کل بافت با سطوح ایمنی 0/01 و در اولویت کاملا ناایمن است قرار دارند همچنین نتایج مدیریت بهینه بافت مسکونی در برابر خطر زمین لرزه به این صورت است که 200696 متر مربع یعنی 19/77درصد از مساحت کل بافت با سطوح ایمنی 0/01 و در اولویت کاملا ناایمن است قرار دارند که بیشترین سهم از ساختمان ها را به خود اختصاص داده است.
واژگان کلیدی: تاب آوری، ایمنی، بافت مسکونی، جهرم، hot spot
