Özet:

 Objective: The relationship between the indices and reflectances obtained by using different satellite images Triplesat, Landsat 8, and soil erosion parameters erosion rate, dispersion rate, structure stability, clay ratio, aggregate stability, and soil crust index within the boundaries of Vezirköprü district of Samsun province. is to be revealed. Material and Methods: It was carried out in three stages: analyzing soil erosion sensitivity on a total of 32 soil samples taken at 100 x 100 m grid intervals from the study area, obtaining indices and reflectances of Triplesat and Landsat satellite images, and comparing the analysis results with the indices of satellite images. Results: The correlations between the reflectance values obtained from the Red, Green and Blue bands of the Landsat satellite data and the erosion rate were determined to be higher than the reflectances of the Triplesat satellite. No significant correlations were obtained between the aggregate stability and crust ratio properties of the soils and the indices. Higher positive correlations were determined between erosion rate and dispersion rate and indices. Conclusion: It has been seen that the aggregate stability AS contents of the soils are in a higher relationship with the indices obtained from Triplesat satellite images, and the erosion rate is higher with the indices obtained from Landsat satellite images.

 Amaç: Samsun ili Vezirköprü ilçe sınırları içerisinde 466.06 dekar alanda farklı uydu görüntüleri Triplesat, Landsat 8 kullanılarak elde edilen indis ve reflektansları ile toprak erozyon parametreleri erozyon oranı, dispersiyon oranı, strüktür stabilitesi, kil oranı, agregat stabilitesi ve toprak kabuk indeksi arasındaki ilişkinin ortaya konulmasıdır. Materyal ve Yöntem: Çalışma alanı içerisinden 100 x 100 m grid aralıklarla alınmış toplam 32 toprak örneğinde toprak erozyon duyarlılığına yönelik analizlerin yapılması, Triplesat ve Landsat uydu görüntülerine ait indis ve reflektansların elde edilmesi, analiz sonuçlarının uydu görüntülerine ait indislerle karşılaştırılması olmak üzere üç aşamada gerçekleştirilmiştir. Araştırma Bulguları: Landsat uydu verilerinin Red, Green ve Blue bantlarından elde edilen reflektans değerleri ile erozyon oranı arasındaki ilişkiler Triplesat uydusu reflektanslarına göre daha yüksek olarak belirlenmiştir. Toprakların agregat stabilitesi ve kabuk oranı özellikleri ile indisler arasında önemli seviyede korelasyonlar elde edilmemiştir. Erozyon oranı ve dispersiyon oranı ile indisler arasında daha yüksek pozitif yönlü ilişkiler belirlenmiştir. Sonuç: Toprakların agregat stabilitesi AS içerikleri ile Triplesat uydu görüntülerinden elde edilen indislerde, erozyon oranında ise Landsat uydu görüntülerinden elde edilen indisler ile daha yüksek ilişki içerisinde olduğu görülmüştür.
