چکیده مقاله :
بر اساس نتایج تحقیقات و شاخص های زمین ساختی، منطقه در وضعیت زمین ساختی متوسط قرار دارد. از عوامل تهدید کننده در منطقه می توان به تاثیر گسل میناب بر بالا آمدگی منطقه اشاره کرد که باعث افزایش شیب منطقه در قسمت های شمالی می شود. این امر به نوبه خود باعث افزایش دبی آب و طغیان رودخانه ها در نواحی پایین دست شده و باعث ناپایداری شیب و رانش زمین در منطقه می شود. هدف از این پژوهش ارائه بینش های ارزشمندی در مورد تأثیر ساختارهای زمین شناسی منطقه بر روی چالش های زمین شناختی و زیست محیطی آینده می باشد. با محاسبه پارامترهای مورفوتکتونیکی و شاخص های مورفومتری به منظور برآورد مخاطرات زمین ساختی گسل میناب به نقش آن بر روی مخاطرات زمین شناختی-زیست محیطی پرداخته شده است. بر این اساس تاثیر گسل میناب بر بالا آمدن منطقه می تواند شیب منطقه را در قسمت های شمالی افزایش داده و منجر به افزایش جریان آب و طغیان رودخانه ها در نواحی پایین دست شود. این امر می تواند باعث ناپایداری شیب و رانش زمین در منطقه شود. از نظر خطرات تکتونیکی، وجود گسل میناب و فعالیت تکتونیکی مرتبط با آن می تواند منجر به خطرات زمین ساختی مختلف از جمله زمین لرزه شود. در نتیجه، در حالی که گسل میناب و فعالیت های زمین ساختی مرتبط با آن می تواند چالش های زیست محیطی قابل توجهی را ایجاد کند، با برنامه ریزی صحیح و درک شرایط زمین ساختی، می توان این چالش ها را کاهش داد و به توسعه پایدار منطقه کمک کرد.
Based on the research results and tectonic indicators, the region is in an average tectonic state. One of the threatening factors in the region is the effect of the Minab fault on the rise of the region, which increases the slope of the region in the northern parts. This, in turn, causes an increase in water flow and flooding of rivers in the downstream areas and causes slope instability and landslides in the region. The purpose of this research is to provide valuable insights about the influence of the geological structures of the region on the future geological and environmental challenges. By calculating morphotectonic parameters and morphometric indices in order to estimate the tectonic risks of Minab fault, its role on geological-environmental risks has been discussed. Based on this, the effect of the Minab fault on the rise of the region can increase the slope of the region in the northern parts and lead to an increase in water flow and river flooding in the downstream areas. This can cause slope instability and landslides in the region. In terms of tectonic risks, the existence of the Minab fault and its related tectonic activity can lead to various tectonic risks, including earthquakes. As a result, while the Minab fault and related tectonic activities can create significant environmental challenges, with proper planning and understanding of tectonic conditions, these challenges can be reduced and lead to sustainable development. The area helped.
