چکیده
مقدمه:
شهر لنگرود به دلیل موقعیت جغرافیایی خود در معرض مخاطرات محیطی، به‌ویژه زلزله، قرار دارد. از آنجا که شهرها دارای کالبد و روح هستند، بررسی تاب‌آوری آن‌ها در برابر این مخاطرات ضروری است تا بتوان سامانه‌های ساخته‌شده توسط بشر و سامانه‌های طبیعی را به سمت تاب‌آور شدن پیش برد.
هدف: هدف این تحقیق بررسی الگوی یکپارچه تاب‌آوری و ساختار کالبدی، اجتماعی و اقتصادی شهر لنگرود در برابر مخاطرات محیطی ناشی از رخداد زلزله است.
روش شناسی تحقیق: روش این پژوهش غیر آزمایشی و از نوع همبستگی است. این تحقیق از نوع کاربردی و از لحاظ زمانی مقطعی است. پژوهش به‌صورت میدانی انجام شده و از منابع کتابخانه‌ای و روش اسنادی نیز بهره گرفته شده است.
قلمرو جغرافیایی پژوهش: این پژوهش در شهر لنگرود انجام شده است که یکی از شهرهای مهم استان گیلان در شمال ایران است.
یافته‌ها: پردازش اطلاعات با بررسی مدل‌های پارامترهای شاخص ایمنی، تخمین خسارات زلزله به ساختمان‌ها در سامانه WARED، بررسی زمین‌شناسی اقتصادی، و بیشینه شتاب زمین (PGA) که مهم‌ترین پارامتر لرزه‌ای است، انجام شد.
نتایج: نتایج نشان می‌دهد که با بررسی منحنی شکست‌های استخراج‌شده از پروژه HAZUS، شهر لنگرود از منظر تاب‌آوری و ساختار کالبدی، اجتماعی و اقتصادی در برابر مخاطرات محیطی، به‌ویژه زمین‌لرزه، تا حد قابل قبولی مقاوم است.
Introduction: The city of Langarud, due to its geographical location, is exposed to environmental hazards, particularly earthquakes. Since cities possess both physical and spiritual aspects, examining their resilience against these hazards is essential to enhance the resilience of both human-made and natural systems.
Objective: This study aims to investigate the integrated model of resilience and the socio-economic and physical structure of the city of Langarud against environmental hazards caused by earthquakes.
Research Methodology: This non-experimental research is of a correlational type. It is an applied study with a cross-sectional time frame. The research was conducted in the field and utilized both library resources and documentary methods.
Geographical Scope of the Study: This research was conducted in the city of Langarud, an important city in Gilan Province, northern Iran.
Findings: Data processing was based on examining models of safety index parameters, estimating earthquake damages to buildings using the WARED system, assessing economic geology, and considering peak ground acceleration (PGA), which is the most critical seismic parameter.
Results:. The results indicate that by examining the fragility curves extracted from the HAZUS project, the city of Langarud is reasonably resilient in terms of its socio-economic and physical structure against environmental hazards, particularly earthquakes
