Özet:

 Erosion is a degradation factor that poses a major threat to land resources on a global scale. This study was carried out in the lands forming the southwestern part of the Biga Peninsula in northwestern Türkiye. ICONA Instituto Nacional para la Conservación de la Naturaleza model was used to determine the erosion risk status in the study. In the ICONA model; slope, geology, land cover and vegetation density data are systematically evaluated and the result maps are produced in geographic information systems GIS. In the model, firstly slope classes were derived using digital elevation model DEM. The slope classes were combined with geological units which categorized according to the model and a potential erosion risk map of the study area was produced. Then, land cover and vegetation cover maps were produced to generate the soil protection map. These parameters were used to categorize the different land use types on the land according to the model and to determine the vegetation cover rate on the land. In this context, Coordination of Information on the Environment CORINE 2018 data were used. The produced potential erosion map and soil protection map were combined according to the ICONA model and the final ICONA map was produced. According to the result map; it was revealed that 0.19, 33.32, 42.32, 21.82 and 2.35 of the study area lands have very low, low, medium, high and very high erosion risk, respectively. The data produced by this study have the potential to provide significant information for the conservation and management of natural resources. In addition, it has been observed that the ICONA model is useful in determining the erosion risk of large areas and provides important opinions. It is recommended to apply this model in different regions.

 Erozyon, arazi kaynakları üzerinde küresel ölçekte bir tehlike oluşturan bir degradasyon unsurudur. Bu çalışma Türkiyenin kuzeybatısında bulunan Biga yarımadasının güneybatı bölümünü oluşturan arazilerde gerçekleştirilmiştir. Çalışmada erozyon risk durumu belirlemek için ICONA Instituto Nacional para la Conservación de la Naturaleza modeli kullanılmıştır. ICONA modelinde; eğim, jeoloji, arazi örtüsü ve vejetasyon yoğunluğu verileri bir sistematik içinde değerlendirilmekte ve sonuç haritaları coğrafi bilgi sistemleri CBS ortamında üretilmektedir. Modelde ilk aşamada dijital yükseklik modeli DEM kullanılarak eğim sınıfları oluşturulmuştur. Oluşturulan eğim sınıfları model doğrultusunda kategorize edilerek jeolojik birimler ile birleştirilmiş ve çalışma alanının potansiyel erozyon risk haritası oluşturulmuştur. Daha sonra toprak koruma haritasını oluşturmak için arazi örtüsü ve vejetasyon yoğunluğu haritaları üretilmiştir. Bu parametreler arazide bulunan farklı arazi kullanım türlerinin model doğrultusunda kategori edilmesi ve arazideki vejetasyonun örtü oranını belirlemede kullanılmıştır. Bu kapsamda Coordination of Information on the Environment - Çevresel Bilginin Koordinasyonu CORINE 2018 yılı verileri kullanılmıştır. Üretilen potansiyel erozyon haritası ve toprak koruma haritası ICONA modeli doğrultusunda birleştirilerek sonuç ICONA haritası üretilmiştir. Sonuç haritası verilerine göre; çalışma alanı arazilerinin 0.19unda çok az, 33.32sinde az, 42.32sinde orta, 21.82inde yüksek ve 2.35inde çok yüksek erozyon riski olduğu ortaya konmuştur. Gerçekleştirilen bu çalışma ile üretilen veriler doğal kaynakların izlenme, değerlendirme ve yönetimi açısından önemli bilgiler sunabilecek potansiyele sahiptir. İlaveten ICONA yönteminin geniş alanların erozyon riskinin belirlenmesinde faydalı olduğu ve önemli fikirler verdiği gözlemlenmiştir. Bu modelin daha farklı bölgelerde de uygulanması tavsiye edilmektedir.
