چکیده

پوشش جنگلی بلوط (Quercus spp.) یکی از مهم‌ترین بوم‌سازگان‌های زنده در غرب کشور و استان کرمانشاه است. از نیازهای مهم مدیریتی این پوشش می‌توان به برآورد تبخیر- تعرق یا نیاز آبی اشاره کرد. استفاده از سنجش‌ازدور، یکی از روش‌های کاربردی در برآورد تبخیر- تعرق پوشش گیاهی در سطوح مختلف است. در پژوهش پیش‌رو از الگوریتم سبال و چهار تصویر ماهواره لندست ۵ مربوط به تیر و مردادماه ۱۳۸۹ (ژوئن و ژوئیه و اوت سال ۲۰۱۰ میلادی) برای برآورد مقدار تبخیر- تعرق پوشش جنگلی در منطقه رباط‌‌ماهیدشت در استان کرمانشاه استفاده شد. سپس با استفاده از تصاویر ماهواره سنتینل، محدوده جنگلی منطقه رباط‌ماهیدشت استخراج شد و با نقشه تبخیر- تعرق تطبیق داده شد. براساس نتایج، مقدار میانگین تبخیر- تعرق 24 ساعته پوشش جنگلی در بازه زمانی مورد مطالعه بین ۴/۳ تا ۰۹/۵ میلی‌متر متغیر بود که بیانگر نیاز آبی قابل‌توجه این پوشش است. ضریب همبستگی بین تبخیر- تعرق برآوردشده با سبال و اندازه‌گیری‌‌شده با لایسی‌متر 9967/0 و اختلاف مطلق بین آن‌ها 53/0 میلی‌متر در روز به‌دست ‌آمد که نشان‌دهنده خطای کمتر از ۱۰ درصد و عملکرد قابل‌قبول الگوریتم سبال است. این الگوریتم در صورت وجود توالی مناسب تصاویر و داده‌های سنجنده‌های دیگر مانند تصاویر سنتینل می‌تواند برای طبقه‌بندی تراکمی و بررسی سلامتی جنگل‌ها استفاده شود.

چکیده [English]

     Oak (Quercus spp.) forest cover is one of the most important living ecosystems in the western region of Iran and the Kermanshah Province. One of the important managerial needs of this cover is the water requirement of the oak plant. Currently, determining the amount of water required by the oak plant is one of the main priorities of the country's natural resources sector. Among the practical methods for estimating the evapotranspiration of vegetation (water requirement) at different levels are remote sensing techniques. In this study, in order to determine the rate of evapotranspiration of forest cover in the Robat Mahidasht region in the Kermanshah Province, the SEBAL algorithm and four images of Landsat 5 in the period of June, July, and august of 2010 were used. Then, using Sentinel satellite images, the forest areas of the Robat-Mahidasht region were extracted and matched with the calculated evapotranspiration map. Based on the obtained results, the average rate of 24-hour evapotranspiration of forest cover in the desired time period has varied between 3.4 to 5.09 mm. The correlation coefficient between the estimation of evapotranspiration by SEBAL and lysimetric measurement in Mahidasht region was about 0.9967 and the absolute difference between them was about 0.53 mm per day, which indicates an error of less than 10%. The estimation of SEBAL algorithm is acceptable. Remote sensing technique and the SEBAL algorithm can be used in the compression classification and even the health of forests if there is a suitable sequence of images and with the help of satellite data of other sensors such as Sentinelimages.
