SUMMARY
AbstractThe increasing world population began to concentrate in cities especially after the Industrial Revolution. After the Second World War, societies with over consumption have brought with it the waste problem. In particular, the growth of urban areas, both as a population and as an area, has led to the increase of waste material and the existing landfills located in the border of the city. This situation, which can lead to health consequences, has led local and central governments to find new landfills. When the literature is examined, it has been seen that studies about the subject have been made. In this study, alternative landfill areas were determined in Usak Central District by using geographical information systems and analytic hierarchy process which is one of the multi criteria decision making methods. The analytical hierarchy process used in the method part is the multi criteria decision making method, which allows to determine the degree of importance based on the Pair-wise comparisons of the determined criteria. In determining the alternative sites, rivers, settlements, lands, faults, landslide, slope, agricultural value of the area, land use type, transportation networks, geological formations, large soil classes and distance to airport were taken into consideration. The maps of the criteria were prepared using ArcMap software. Euclidean distance analysis was applied and reclasify was performed. Distance between settlements and rivers was determined as the most important criteria at the end of the Pair-wise comparisons. Weighted overlay was applied by using weight ratios determined by analytical hierarchy method and alternative sites were determined. As a result of the analysis, six different sites in total 1522 hectares were found suitable near Diskaya, Taskonak, Yenisehir, Bagbasi, Bozköy, Gögem and Karlik villages. The results of the study were limited to GIS analysis. The presence of a dense settlement and stream drenage in the research area has limited the storage space.ÖzArtan dünya nüfusu özellikle Sanayi Devriminden sonra sehirlerde yogunlasmaya baslamistir. Ikinci Dünya Savasindan sonra asiri tüketime yönelen toplumlar atik problemini de beraberinde getirmistir. Özellikle sehirsel alanlarin hem nüfus hem de alan olarak büyümesi atik madde artisinin yaninda mevcut çöp depolama alanlarinin sehrin içinde kalmasina da neden olmustur. Sagligi tehlikeye sokabilen sonuçlara sebep olan bu durum yerel ve merkezi yönetimleri yeni deponi alanlari bulmaya itmistir. Literatür incelendiginde konu ile ilgili çalismalarin yapildigi görülmüstür. Bu çalismada cografi bilgi sistemleri ve çok kriterli karar verme yöntemlerinden bir tanesi olan analitik hiyerarsi kullanilarak Usak Merkez ilçesinde alternatif atik depolama alani yerleri belirlenmistir. Yöntem kisminda kullanilan analitik hiyerarsi, belirlenen kriterlerin ikili karsilastirmalarina dayanan önem derecelerinin belirlenmesini saglayan ÇKKV yöntemidir. Çalismada alternatif sahalarin belirlenmesinde akarsular, yerlesim alanlari, baki, faylar, heyelan, egim, sahanin tarimsal degeri, arazi kullanim sekli, ulasim aglari, jeolojik formasyonlari, büyük toprak siniflari ve havaalanina olan mesafe olmak üzere on iki kriter dikkate alinmistir. Kriterlerin haritalari ArcMap yazilimi kullanilarak hazirlanmistir. Çalismada öklid mesafe analizi uygulanarak yeniden agirliklandirma islemleri yapilmistir. Ikili karsilastirmalar sonunda yerlesmelere ve akarsulara olan uzaklik en önemli ölçütler olarak belirlenmistir. Analitik hiyerarsi yöntemi ile belirlenen agirlik oranlari kullanilarak çakistirma islemi (weighted overlay) uygulanmis ve alternatif sahalar belirlenmistir. Analiz sonucunda Diskaya, Taskonak, Yenisehir, Bagbasi, Bozköy, Gögem ve Karlik köyleri yakinlarinda toplam 1522 hektarlik alti farkli saha uygun bulunmustur. Arastirmanin sonuçlari CBS analizleri ile sinirli tutulmustur. Arastirma sahasinda yogun bir yerlesme ve akarsu aginin bulunmasi depolama alani yapilabilecek yerleri sinirlamistir.
