چکیده مقاله :
امروزه کسب آگاهی و دانش در رابطه با پوشش گیاهی و سلامت آن نقش مهمی را در مدیریت مناطق حفاظت شده و حفاظت از گونههای گیاهی و جانوری آن دارد. سنجش از دور فنآوری بسیار مفیدی است که جهت بررسی پوشش گیاهی از گذشته تاکنون نسبت به سایر روشها ارجحیت داده میشود. استفاده از شاخصهای پوشش گیاهی در تعیین گستره پوشش گیاهی یکی از راههای موجود در آشکارسازی تغییرات پوشش گیاهی میباشد. در تحقیق حاضر بهدلیل شرایط اتمسفری مناسب و درصد ابرناکی کمتر از 10 درصد از تصاویر ماه ژوئن سالهای 1987و 2016 و ماه می سال 2003 مربوط به سه سنجنده TM، ETM+ و OLI ماهواره لندست و از سه شاخص NDVI، SAVI و EVI برای شناسایی و طبقهبندی پوشش گیاهی منطقه مورد مطالعه استفاده گردید. از روشCross classification برای مقایسه شاخصهای پوشش گیاهی با نقشه پوشش اراضی تهیه شده از روش طبقهبندی هیبرید و انتخاب بهترین شاخص پوشش گیاهی در طبقهبندی استفاده گردید. ضریب کاپای بهدست آمده از مقایسه نقشه پوشش گیاهی با استفاده از شاخص NDVI و نقشه پوشش اراضی برای سالهای 1987، 2003 و 2016 بهترتیب 87/0، 82/0 و 87/0 بود که مقادیر بالاتری نسبت به دو شاخص پوشش گیاهی دیگر را در سه سنجنده دارا بود. همچنین نتایج آشکارسازی تغییرات سی ساله، بیانگر کاهش 27/9153 هکتار از ارسزارهای منطقه مورد مطالعه بوده است که 43/9092 هکتار از آن به طبقه اراضی مرتعی و 84/60 هکتار به اراضی بایر تبدیل شده است.
Today acquisition of knowledge regarding to the health of vegetation has an important role in the management of protected areas and conservation of plant and animal species. Remote sensing is a useful technology for investigation of vegetation since past to present that have priority over other method. Using vegetation indices in determination of the spatial distribution of vegetation is one of the ways for vegetation change detection. In this study, due to suitable atmospheric conditions and percentage of cloud cover less than 10%, the images of June 1987 and 2016 and May 2003, TM, ETM + and OLI sensors of Landsat and three vegetation indices, including NDVI, SAVI and EVI were used for the identification and classification vegetation cover. The cross-classification method was used to compare vegetation indices with land cover map which produced by hybrid classification and selecting the best vegetation index in classification. Kappa coefficient obtained from comparison of vegetation map using NDVI index and land cover map for 1987, 2003, and 2016 were 0.87, 0.82 and 0.87, respectively, which were higher than others. Also, the results of 30-year-old reveal a decrease of 9153.27 hectares of Juniperus in the studied area that 9092.43 ha were converted to rangelands and 60.84 ha to barren lands.
