| پروژه های سدسازی از مراحل آغازین خود، ساختار محیط زیست را تحت تأثیر قرار می دهند . این تغییرات می تواند باعث کاهش یکپارچگی و افزایش ازهم گسیختگی منطقه شود. هدف این تحقیق بررسی روند تغییرات ساختاری پوشش جنگلی حوزه آبخیز شفارود با توجه به احداث سد شفارود است. برای رسیدن به این هدف 3 تصویر ماهواره ای متعلق به سال های 2013،2000 و2017 استفاده شد وتصحیح های (هندسی و اتمسفری) بر روی تصاویر اعمال و با روش طبقه بندی حداکثر احتمال نقشه کاربری اراضی منطقه برای هر مقطع تهیه شد که به ترتیب دارای صحت کاربری و ضریب کاپای بالاتر از 86 % و 83/0 بودند. سپس با استفاده از نرم افزار Patch Analyst تجزیه و تحلیل متریک های سیمای سرزمین شامل CA ، NP ، TE ، ED و MPS در سطح کلاس، ازهم گسیختگی و تخریب زیستگاهی منطقه، بررسی شد. نتایج بیانگر افزایش از هم گسیختگی و نامساعد شدن شرایط زیستگاهی در جنگل های هیرکانی و جایگزینی گسترده پوشش های جنگلی با مناطق بدون پوشش است. نتایج بدست آمده همچنین نشان داد، که کاهش تعداد لکه ها مابین سال های 2013 تا 2017 تخریب متمرکز ایستگاهی در کوتاه مدت در محل احداث پروژه را ایجاد کرده ، این در حالیست که هنوز ساختمان سد و نیاز مندی های آن ماننددسترسی ها و کلیه تاسیسات سد کامل نشده است . این امر ضرورت مطالعه های زیست محیطی را در احداث سدها و هماهنگی قابلیت های اکوسیستم را در جهت حفظ منابع نشان می دهد. | ||

| چکیده [English] | ||
| Dam construction affect the structure of the environment from its early stages. These changes can reduce the integrity and increase the fragmentation of the landscapes and subsequently diminish the linkages among the wildlife habitats. The purpose of this research is to investigate the structural changes in the forest land cover of Shafarud watershed due to the construction of Shafarud dam. In order to the achieve this goal, using RS and GIS techniques the land use/cover was created, and using Patch Analyst software,land cover metrics including CA, NP, TE, ED, and MPS in the class level, were analyzed and fragmentation and habitat destruction were examined. Investigation of the results of the metrics analysis, revealed deterioration and fragmentation of habitats at the level of the landscape class in the study area. | ||
