چکیده مقاله :

زمینه و هدف: مطالعه میزان تغییرات و تخریب منابع در سال های گذشته می تواند در برنامه ریزی جهت استفادة بهینه از آن و کنترل و مهار تغییرات غیر اصولی در آینده گام مهمی به شمار آید. از آنجا که این تغییرات در سطوح وسیع و گسترده اتفاق می افتد، تکنولوژی سنجش از دور ابزاری ضروری و ارزشمند جهت پایش تغییرات می باشد. هدف از تحقیق حاضر، پایش تغییرات پوشش اراضی در حوضه آبخیز قره سو در استان اردبیل با تکنیک سنجش از دور است. روش بررسی: دراین تحقیق تغییرات پوشش اراضی طی سی سال از سال 1365 الی 1395 مورد پایش قرار گرفت.ابتدا تصاویر ماهواره لندست مربوط به ماه جولای سال های 1985، 2000 و 2015 تهیه و پس از تصحیح هندسی و ارتفاعی، طبقه بندی تصاویر به روش نظارت شده با متد حداکثر احتمال انجام پذیرفت. به منظور افزایش دقت طبقه بندی از شاخص NDVI، DEM و لایه شیب استفاده شد و دقت طبقه بندی با شاخص کاپا و صحت کلی مورد بررسی قرار گرفت. یافته ها: بر اساس نتایج در دوره اول (1380-1365) 43/20 درصد، در دوره دوم (1395-1380) 426/41 درصد و در سی سال (1395-1365) 99/27 درصد از منطقه دچار تغییر کاربری شده است که در هر سه دوره تغییرات کاربری زراعت دیم بیشترین مقدار را دارد. بحث و نتیجه گیری: نتایج تحقیق حاضر نشان دهنده این امر است که علیرغم بالا بودن قدرت تصاویر ماهواره لندست در تهیه نقشه کاربری اراضی، می توان با استفاده از شاخص ها و لایه های جانبی نظیر NDVI، ارتفاع و درصد شیب قدرت تفکیک کاربری ها از یکدیگر را بهبود بخشید.

چکیده انگلیسی:

Background and Objective: Studying the extent of change and destruction in resources in previous can contribute to efficient planning and utilization of these resources and limiting similar adverse changes in the future. Since changes in resources occur over large expanses of land, remote sensing technology can serve as a essential and valuable tool for monitoring these changes. The purpose of this study was to monitor the land cover changes in Qaresu watershed in Ardabil province using the remote sensing technique. Methods: In this study land cover changes was consulted in 30 years from 1985 to 2015. Landsat images of the study area pertaining to July 1985, 2000 and 2015 were acquired. After geometric and elevation corrections, the images were classified by the supervised approach using the maximum likelihood method. The NDVI index, DEM, and slope layers were used to enhance the image classification accuracy. Classification accuracy was assessed with Kappa index and overall accuracy indexes. Findings: The results showed 20.43% change in the watershed’s land uses over the period from 1985 to 2000, 41.426% over the period from 2000 to 2015, and 27.99% over the period from 1985 to 2015. In all three periods, the greatest changes were in dry farming. Discussion and Conclusion: Results showed despite high capability of Landsat images in mapping land use, using additional layers like NDVI, elevation and slope percent can improve separation accuracy of land using.
