چکیده

با توجه به افزایش فشارهای انسانی بر سوحل دریایی، همواره نیاز اساسی به تفهیم و ترسیم چالش‌های پیچیده پایداری و کمک به ساماندهی تحقیقات احساس می‌گردد. بنابراین با تدوین چنین چارچوب جامعی می‌توان به پیش‌بینی تغییرات و پشتیبانی تصمیم‌های مدیریتی و همچنین میزان تاب‌آوری محیط‌زیست منطقه دست یافت. در این زمینه چارچوب مفهومی مدل عوامل پیشران، فشار، وضعیت، اثرات و پاسخ‌ها موسوم به DPSIR یکی از رویکردهایی است که می‌تواند در مناطق ساحلی-دریایی مورد استفاده قرار گیرد. از طرفی قشم نیز به‌عنوان بزرگترین و مهمترین جزیرة و از مناطق استراتژیک حوزة خلیج فارس می‌باشد. در دهه‌های اخیر، ویژگی‌های خاص این منطقه به‌همراه محیط‌زیست متنوع و حساس سبب تبدیل این محدوده به یکی از قطب‌های عمده گردشگری فرهنگی، طبیعی و زمین‌شناسی کشور شده است. بر این اساس، در تحقیق حاضر با رویکردی توأم به بررسی تاب‌آوری محیط‌زیست دریایی در کرانه‌های شمالی سواحل جزیره قشم با استفاده از معیارهای اقتصادی- اجتماعی پرداخته شد. در این راستا به جهت کمّی‌سازی هرچه بهتر نتایج، چارچوب مفهومی مدل DPSIR در تلفیق با مدل معادلات ساختاری (SEM-PLS) که از رویکردهای غیرآزمایشی است، به‌کار گرفته شد. با توجه به نقشه‌شناختی فازی، شاخص اقتصادی در این منطقه به‌ترتیب با وزن‌های 0/62، 0/62 و 0/5 با شاخص نهادی- مدیریتی و زیستی دارای رابطه دو سویه و مثبت می‌باشد، این عامل با وزن 65/0 با شاخص اجتماعی- فرهنگی رابطه دو سویه و منفی دارد. همچنین، شاخص اقتصادی با وزن 0/69 با شاخص فیزیکی و شیمیایی رابطه یک‌سویه و منفی دارد.

چکیده [English]

There is always an adamant need to comprehend and draw the complex challenges of sustainability and help to organizing studies due to the increasing human-related pressures on coastal zones. Hence, by formulating such a comprehensive framework, it could be possible to anticipate changes and supporting managerial decisions, as well as the degree of environment resilience in the region. One of the approaches utilized in littoral zones is the conceptual framework of drivers, pressure, status, impact and responses, DPSIR. Qeshm Island, the largest island in the Persian Gulf, accounts for being the most vital and strategic area in the region. In recent decades, Qeshm has become one of the major cultural, natural, geological as well as tourism hubs of the country due to its unique regional characteristics, along with its biodiversity and environmental sensitivity. Thereby, in the present research, a combined approach was followed to explore the resilience of the marine environment in the northern coast of the Qeshm Island by taking advantage of the socio-economic criteria. In this respect, the conceptual framework of the DPSIR model is utilized in combination with the structural squation model (SEM-PLS), which is one of the non-experimental techniques, to quantify the results in the best possible manner. On the basis of the fuzzy cognitive map (FCM), the Regional economic index bears the weights of 0.62, 0.62 and 0.5 along with the Institutional-managerial and Biological indexes, respectively, denoting a two-way positive correlation whereas having a two-way but adverse correlation with a weight of 0.65 in terms of the Socio-cultural index. There is also a one-way and negative relationship, as to the Economic index, with a weight of 0.69 in relevance with the Physio-chemical index likewise.
