Su, insan yaşamı için temel ihtiyaçlardan biridir. Dolayısıyla akarsu havzaları diğer alanlara göre daha fazla nüfuslanmıştır. Çalışma sahasını oluşturan Melet Irmağı’nın orta ve aşağı çığırı da yoğun nüfuslu alanlardan biridir. Havzada nüfusun artması arazi kullanımında da değişmelere sebep olmuştur. Bu çalışmanın amacı, 2002-2015 yılları arasında, çalışma alanında meydana gelen arazi kullanımı değişimlerini coğrafi açıdan incelemektir. Melet Irmağı yukarı çığırından Topçam Boğazı ile ayrılan araştırma sahası, Karadeniz Bölgesi’nin Orta ve Doğu bölümleri arasında yer almakta ve yaklaşık 865 km2 yüz ölçüme sahip bulunmaktadır. Bu çalışmada Coğrafi Bilgi Sistemleri, Uzaktan Algılama yöntemleri ve arazi incelemeleri bir arada kullanılmıştır. Arazi kullanımındaki zamansal değişim 18 Ekim 2002 tarihli Landsat 7 TM uydu görüntüsü ve 28 Eylül 2015 tarihli Landsat 8 OLI/ TIRS uydu görüntüsü ile arazi çalışmaları sırasında elde edilen veriler karşılaştırılarak belirlenmiştir. Bu amaçla United States Geological Survey’in web sitesinden çalışma alanına ait Landsat uydu görüntüleri temin edilmiştir. ENVI 5.1 programı yardımıyla uzaktan algılama analizleri yapılmış, elde edilen sonuçlar ArcGIS 10.2 programı kullanılarak haritalanmıştır. Yapılan incelemeler sonucunda, 2002-2015 yılları arasında araştırma sahasındaki ormanların 103 km2 alan kaybettiği, tarım arazilerinin ise 122,9 km2 alan kazandığı anlaşılmıştır. Nitekim saha çalışmaları sırasında ormanların ve meraların tahrip edildiği, yerlerine fındık ve kivi bahçelerinin kurulduğu gözlenmiştir. Doğal bitki örtüsüne zarar veren ve erozyonu destekleyen bu olaylar, yabani hayvanların yaşam alanlarını da sınırlamaktadır. Bu nedenle, çalışma alanının doğal bitki örtüsü, yaban hayatı varlığı ve tarımsal faaliyetleri birlikte değerlendirilmeli ve sürdürülebilir bir kullanım yöntemi geliştirilmelidir.
Water is one of the basic needs for human life. Therefore, river basins are densely populated than other areas. The middle and lower catchment of the Melet River, which is the study area, is also one of the densely populated areas. Increasing population in the study area caused some changes in land use. The aim of this study is to investigate the land use changes that occurred in the study area between 2002 and 2015 in terms of geography. The study area, which is separated from the upper catchment of the Melet River by Topçam Strait, is located between the Middle and Eastern Sections of the Black Sea Region and has an area of approximately 865 km2. In this study, Geographical Information Systems, Remote Sensing methods and field investigations were used together. The temporal change in land use was determined by comparing the Landsat 7 TM satellite image of 18 October 2002 and the Landsat 8 OLI/TIRS satellite image of 28 September 2015 with the data obtained during field works. For this purpose, the aforementioned images are obtained from the website of The United States Geological Survey. Remote Sensing analysis is performed with ENVI 5.1 program and the results are mapped using ArcGIS 10.2 program. As a result, it was understood that the forests in the study area lost 103 km2 areas, agricultural lands have gained an area of 122.9 km2 between 2002 and 2015. During the field studies, it was observed that forests and pastures were destroyed and hazelnut and kiwi gardens were installed in their places. These events, which damage the natural vegetation and supports erosion, also limit the habitats of the wild animals. Therefore, the natural vegetation, wildlife existence, and agricultural activities of the study area should be assessed together and developed a sustainable use method.
