Abstract	Toprak kaymalari, daglik bolgelerdeki en zarar verici dogal felaketler arasinda yer almaktadir. Her yil, dunyanin dort bir yaninda yuzlerce insan toprak kaymasi neticesinde oluyor. Ayrica, bu olaylarin yerel ve global ekonomi uzerinde de buyuk etkileri bulunmaktadir. Bu calismada, toprak kaymasi tehlikesine sahip bolgeleri tespit etmek uzere lojistik regresyon kullanilarak Baba Haydar Havzasi’nda toprak kaymasi tehlikesi haritasi cikartilmistir. Ilk olarak, havadan cekilmis fotograf yorumlari ve saha incelemeleri kullanilarak toprak kaymasi envanter haritasi hazirlanmistir. Bir sonraki adimda rakim, egim yuzdesi, egim acisi, litoloji, fay hatlarina olan mesafe, nehirler, yerlesim yerleri ve yollar, arazi kullanimi ve yagis miktari olmak uzere toprak kaymasina neden olabilecek on adet faktor, calisma bolgesinde toprak kaymasinda etkin faktorler olarak secilmistir. Ardindan, Cografi Bilgi Sisteminde (GIS) lojistik regresyon modeli kullanilarak toprak kaymasi hassasiyeti haritasi olusturulmustur. Model degerlendirmesi icin ROC ve Pseudo-R2 endeksleri kullanilmistir. Sonuclar, lojistik regresyon modelinin, 0.876’lik ROC degeri ile birlikte Baba Haydar Havzasi’nda toprak kaymasi hassasiyet haritasinin yuksek bir tahmin dogrulugu sagladigini gostermistir. Ayrica sonuclar, havza bolgelerinin yaklasik %44’unun yuksek ve son derece tehlikeli siniflarda yer aldigini ortaya cikartmistir. Sonuc olarak elde edilen toprak kaymasi hassasiyeti haritalari, uygun havza yonetimi uygulamalarinda ve bolgenin surdurulebilir bir sekilde gelistirilmesinde faydali olabilir.
