چکیده مقاله :
چکیده زمینه و هدف: مراتع در اقتصاد کشور، چه از لحاظ تأمین علوفه مورد استفاده دام و چه از دیدگاه حفاظت آب، خاک و خدمات دیگری که به جامعه میدهند، اهمیت ویژهای دارند که مدیریت اصولی این اراضی را ضروری می سازد. مراتع استان گلستان زمانی از بهترین مراتع ایران به حساب میآمدند. اما بهدلیل رشد روز افزون جمعیت و وابستگی شدید اقتصادی آنها به منابع طبیعی از جمله مراتع باعث سیر قهقرایی پوشش گیاهی و نهایتا مراتع گردیده است. پخش سیلاب یکی از عملیات اصلاحی مرتع است که با اهداف معین شده در مناطق مرتعی میتواند اجرا گردد. بر این اساس تعیین مکان مناسب برای پخش سیلاب و نفوذ دادن آن به داخل سفرههای آب زیرزمینی، یکی از مهمترین مراحل انجام این گونه پروژهها میباشد. روش بررسی: مدل AHP [1]روشی مناسب جهت مکانیابی عرصههای پخش سیلاب در حوزههای آبخیز کشور معرفی گردیدهاست. هدف از این مطالعه مکانیابی و اولویتبندی مناطق مناسب پخش سیلاب با استفاده از GIS وAHP در حوزه آبخیز گرگانرود میباشد. همچنین در این تحقیق از روش نمرهدهی دو ارزشی [2] نیز به منظور مقایسه با روش تحلیل سلسه مراتبی استفاده گردید. یافتهها: ابتدا با استفاده از روش AHP مناطق نامناسب تعیین شد، سپس در گزینههای باقی مانده، بر اساس نظراتی که از نتایج مدل بهدست آمده و با اولویت بندی، نقاط مناسب شناسایی گردید که با ضریب تناقص گویی برابر 08/0، میتوان بیان کرد وزن دهی معیارهای مکانیابی مناطق مستعد پخش سیلاب صحیح میباشد. از سویی نتایج این تحقیق با روش تحلیل سلسله مراتبی نشان داد، مناطق پیشنهادی برای اجرای پروژه بخش سیلاب بهطور عمده در شمال و شمال شرقی حوزه میباشند. اما در بررسی عوامل و محدودیتهای طبیعی بر اساس روش بولین هیچ مکان مناسبی برای انجام پروژه بخش سیلاب در حوزه آبخیز گرگانرود پیدا نشد. بحث و نتیجهگیری: به طور کلی میتوان بیان کرد که فعالیت پالایشگاه در منطقه باعث افزایش غلظت کادمیوم در خاک سطحی منطقه شده است. این افزایش به نحوی بوده که باعث شده غلظت آن از حد مجاز نیز بیشتر شود. 4- Analytic Hierarchy Process 5- Boolean
Abstract Background and Objective: Rangelands are very important in country economy in terms of grazing livestock, soil and water conservation and other services to the community. Therefore, systematical and careful management of these lands is necessary. Rangelands of Golestan province were one of the best rangelands of Iran in the past. However, high rate of population growth and sever dependence of the population to natural resources and rangelands caused plant coverage degradation. Floodwater spreading is one of the corrective practices that can be performed with certain goal in the rangelands. Site selection and prioritization of the areas suitable for floodwater spreading and infiltration of flood into the groundwater table are among the most important stages of these projects. Method: GIS and AHP model have been introduced as a suitable method for site selection of the areas appropriate for floodwater spreading system in the Gorgan Rud watershed. In this the Boolean scouring method with two values was used and compared with AHP method. Findings: Initially, the unsuitable areas were determined by AHP method. Then the remaining options derived from model results based on the comments. By site selection, the suitable areas were identified and the obtained inconsistency factor (0.08) proved that criteria weighing for locating the suitable areas for floodwater spreading is correct. Discussion and Conclusion: The results of this study also showed that the areas suggested for floodwater spreading are near the wells and springs, especially in the north and north-west of the watershed. Results showed that investigation of natural factors and constraints based on the Boolean method was not suitable for locating the appropriate areas for floodwater spreading in Gorganrud watershed.
