چکیده .

پوششگیاهی در تحقّق اهداف پدافند غیرعامل نقش بسیار مؤثری را ایفا میکند که با اجرای آن میتوان در زمان بروز جنگ، منافع مادی و انسانی را حفظ و به دشمن ضربه زد. در این راستا، هدف اصلی پژوهش حاضر بررسی تأثیر تغییرات پوششگیاهی بر مکانگزینی سطوح بهینه به منظور انجام عملیات آفندی و پدافندی با استفاده از روش ترکیب خطی وزنی (WLC) در شهرستانهای مرزی شمالغرب کشور است. بدین منظور از روش تصمیمگیری چند معیاره مکانی بهرهگیری شد. در ابتدا با مطالعۀ منابع علمی معیارهای اصلی موثر شناسایی، سپس به دو گروه معیارهای عامل و محدودیت تقسیم شدند. معیارهای عامل با استفاده از روش فازی در محیط نرم افزار TerrSet و معیار محدودیت با استفاده از روش بولین استاندارد شدند. برای تعیین وزن معیارها از روش تحلیل سلسله مراتبی بهرهگیری گردید و تلفیق لایهها به روش ترکیب خطی وزنی (WLC) انجام شد. نتایج وزندهی نشان داد معیارهای پوششگیاهی، جهت شیب، ارتفاع از سطح دریا و درصد شیب به ترتیب دارای بیشترین اهمیت میباشند. با ورود معیار پوششگیاهی سال 2000 و 2022 میلادی به مدل WLC در منطقه مورد مطالعه به ترتیب 70853 و 66271 هکتار سطوح مناسب انجام عملیات نظامی آفندی و پدافندی مکانگزینی شد. در این ارتباط نیز میتوان اینچنین استنباط نمود که منطقه مورد مطالعه در سال 2000 میلادی نسبت به سال 2022 میلادی از پوشش جنگلی غنیتری برخوردار بوده و در واقع تخریب جنگلها در آن سال به مراتب کمتر از حال حاضر بوده است.

چکیده . [English]

Vegetation plays a very effective role in achieving the goals of passive defense, which can be used to protect material and human interests and hit the enemy during war. In this regard, the main goal of the current research is to investigate the effect of vegetation changes on the location of optimal levels in order to carry out offensive and defensive operations using the weighted linear combination (WLC) method in the northwestern border towns of the country. For this purpose, a multi-criteria decision-making method was used. At first, by studying the scientific sources, the main effective criteria were identified, then they were divided into two groups of factor and limitation criteria. Factor criteria were standardized using the fuzzy method in the TerrSet software environment and the limitation criteria were standardized using the Boolean method. Hierarchical analysis method was used to determine the weight of the criteria, and the layers were combined using the weighted linear combination (WLC) method. The weighting results showed that the criteria of vegetation, slope direction, altitude above sea level and slope are the most important, respectively. By entering the vegetation criteria of 2000 and 2022 into the WLC model, 70,853 and 66,271 hectares of suitable areas for offensive and defensive military operations were selected in the study area, respectively. In this connection, it can be concluded that the studied area had a richer forest cover in 2000 than in 2022, and in fact, the destruction of forests in that year was much less than now.
