Bu çalışma ile Samsun ili ilçelerinden Salıpazarı ilçesinde arazi kullanımının zamansal değişimi incelenmiştir. Çalışmada 20 Eylül 1998 ve 13 Eylül 2013 tarihli Landsat uydu görüntüleri ile uzaktan algılama teknikleri ve coğrafi bilgi sistemleri yöntemlerinden yararlanılmıştır. Salıpazarı ilçesinde arazi kullanımının zamansal değişimi için iki farklı döneme ait 1998 ve 2013 uydu görüntüleri kullanılmıştır. Bu görüntülere görüntü işleme ve görüntü zenginleştirme işlemleri uygulanmış ve kontrollü sınıflandırma işlemi yapılarak elde edilen görüntüler arazi kullanım haritalarına dönüştürülmüştür. Bu haritalarla 1998-2013 yılları arasındaki dönemde, arazi kullanımı değişimleri incelenmiştir. Her görüntü için orman, dikili tarım, ekili tarım, tarım dışı ve su yüzeyleri olarak beş temel sınıf belirlenmiştir. 35.085 ha alan olarak hesaplanan araştırma sahasında, 1998 yılında orman alanları 18.065 ha alan iken 2013 yılında 15.778 ha alana gerileyerek %12.65 oranında azaldığı, dikili tarım alanları 13.295 ha alandan 16.186 ha alana genişleyerek %21.74 oranında arttığı görülmüştür. Ekili tarım alanları 3.051 ha alandan 2.004 ha alana gerileyerek %34.31 oranında azaldığı, tarım dışı alanlar 443 ha alandan 930 ha alana genişleyerek %114 oranında arttığı ve su yüzeylerinin 40 ha alandan 177 ha alan genişleyerek %442.5 oranında arttığı tespit edilmiştir. Ayrıca sınıflandırılan her görüntü doğruluk analizine tabi tutulmuştur. 1998 yılı uydu görüntüsü %86,03, 2013 yılı uydu görüntüsü ise %87,22 oranında doğruluk yüzdelerine sahiptir.
This work has been studied by Samsun or the districts of Salıpazari district on the time change of land use. In the study, Landsat satellite images of 20 September 1998 and 13 September 2013 took advantage of remote detection techniques and methods of geographical information systems. The 1998 and 2013 satellite images of two different periods were used for the temporary change of land use in the province of Salıpazari. These images have been applied image processing and image enrichment processes and the images obtained by the process of controlled classification have been converted into land use maps. With these maps in the period between 1998-2013, the changes in land use have been studied. For each image, five basic classes are defined as forest, planted agriculture, planted agriculture, non-agricultural and water surfaces. In the research area calculated as a 35.085 ha area, in 1998 the forest area was 18.065 ha, while in 2013 it decreased to 15.778 ha and decreased by 12.65%, the planted agricultural areas expanded from 13.295 ha to 16.186 ha and increased by 21.74%. It was found that the cultivated agricultural areas declined by 34.31 percent from 3.051 ha to 2.004 ha, the non-agricultural areas increased by 114 percent from 443 ha to 930 ha, and the water surfaces increased by 442.5 percent from 40 ha to 177 ha. Also, every image classified is subject to accuracy analysis. The 1998 satellite image is 86,03% and the 2013 satellite image is 87,22% accuracy.
In this study, the periodic variation of the land use in the district of Salıpazarı was observed based on Landsat satellite images obtained on September 20, 1998 and September 13, 2013. Remote sensing techniques and geographical information systems were employed for the purposes of the current study. Satellite images (1998 and 2013) of two different periods for the temporal change of land use in Salıpazarı district. This satellite images were exposed to controlled classification system following image processing and image enrichment processes. Then, the images obtained were converted into land use maps. With this maps the changes in the use of lands in Salıpazarı between 1998 and 2013 were observed. Land use was classified under five categories which are forest, cultivated agriculture, sown agriculture, non-agricultural lands and water surface for each image transferred. The total research area was 35.085 hectares in this study. While the forest land area was 18.065 hectares in 1998, it was 15.778 hectares in 2013, which means 12.65 % decrease. While the amount of the land allocated to cultivated agriculture was 13.295 hectares in 1998, it was 16.186 hectares in 2013, which means 21.74 % increase. As for the sown agriculture, the amount of the land was 3.051 hectares in 1998, but it was 2.004 in 2013, which means 34.31% decrease. While the amount of non-agricultural lands was 443 hectares in 1998, it was 930 hectares in 2013, which means 114% increase. While the amount of water surface was 40 hectares in 1998, it was 177 hectares in 2013, which means 442% dramatic increase. In addition, each classified image was subjected to accuracy analysis. The 1998 satellite image is 86.03% and the 2013 satellite image is 87.22% accurate.
