Abstract:

 Background and aims Uluabat Lake, as one of Türkiye significant freshwater resources, great value both for its natural beauty and its ecosystem services. However, the lake is negatively impacted by global climate change and human activities. The aim of this study is to reveal the area changes that have occurred in Uluabat Lake, located within the borders of Bursa Province, over a 36-year period from 1987 to 2023, using the NDWI, MNDWI, NDPI, WRI, and AWEInsh indices. For this purpose, the areal change between 1987 and 2023 was analyzed using Geographical Information Systems and as a result of the study, it was determined that the lake lost 12.60 km² 6 between 1987 and 2023. Methods In the study, areal change and validation analyses of Lake Uluabat were conducted using NDWI, MNDWI, NDPI, WRI and AWEInsh water extraction indices. Results The study found that the difference in areal change between 1987 and 2023 in NDWI, MNDWI, NDPI and WRI indices had the same percentile 6 as the original Landsat satellite imagery, while the AWEInsh index was found to be 4 different from the other indices. Conclusions This study is of great significance in determining the lake area using different indices and identifying which of these indices provides more suitable results for the research area. Thus, it is evident that it will serve as a fundamental basis for developing sustainable conservation strategies against climate change and human-induced threats, with the participation of local communities in the protection and management of ecosystems. In this context, the conscious use of water resources and the establishment of effective monitoring systems are critical for maintaining the health of the lake.

 Giriş ve Hedefler Uluabat Gölü, Türkiyenin önemli tatlı su kaynaklarından biri olarak hem doğal güzellikleri hem de ekosistem hizmetleri açısından büyük bir değere sahiptir. Ancak, göl, küresel iklim değişikliği ve insan kaynaklı faaliyetler nedeniyle olumsuz etkilenmektedir. Bu çalışmanın amacı, Bursa ili sınırları içerisinde yer alan Uluabat Gölünde, 1987-2023 yılları arasındaki 36 yıllık dönem boyunca meydana gelen alansal değişimi NDWI, MNDWI, NDPI, WRI ve AWEInsh indekslerini kullanarak ortaya koymaktır. Bu amaç doğrultusunda 1987 ile 2023 yıllarındaki alansal değişim, Coğrafi Bilgi Sistemleri kullanılarak incelenmiş ve çalışma sonucunda gölün 1987 ve 2023 yılları arasında 12,60 km² 6 alan kaybettiği tespit edilmiştir. Yöntemler Çalışmada NDWI, MNDWI, NDPI, WRI ve AWEInsh su çıkarım indeksleri kullanılarak Uluabat Gölünün alansal değişim ve doğrulama analizleri yapılmıştır. Bulgular NDWI, MNDWI, NDPI ve WRI indekslerinde 1987 ve 2023 yılları arasındaki alansal değişim farkının orijinal Landsat uydu görüntüleriyle aynı yüzdelik 6 dilime sahip olduğu tespit edilirken AWEInsh indeksinde diğer indekslerden farklı olarak 4 olduğu tespit edilmiştir. Sonuçlar Bu çalışma, farklı indeksler kullanılarak göl alanının belirlenmesi ve bu indekslerden hangilerinin çalışma alanı için daha uygun sonuçlar sağladığını belirlemek açısından büyük önem taşımaktadır. Böylelikle ekosistemlerin korunması ve yönetimi için yerel halkın da katılımıyla sürdürülebilir koruma stratejileri geliştirilmesinde iklim değişikliği ve insan kaynaklı tehditlere karşı temel bir dayanak oluşturacaktır. Bu bağlamda, su kaynaklarının bilinçli kullanımı ve etkili denetim sistemlerinin oluşturulması, gölün sağlığının korunması için kritik öneme sahiptir.
