Abstract
In countries that show spatial variety over short distances such as Turkey, wrongunconscious land use practices increase the number and impact area of disasters which cause life and property losses. Landslide is one of these disasters. In this study, we produced base maps for the Province of Kilis using GIS and remote sensing methodologies. Base maps in question were created taking parameters effective in the event of landslide into account. The research results showed that 14% of the Province of Kilis, in the west and northwestern of it in particular, had very highhigh landslide risk. In this context, local administrators should consider, during land use planning, these sites where the landslide risk is high-very high. Otherwise, possible landslides may cause losses of life and property. In addition, the foundation of “the Natural Disaster Planning Center of the Province of Kilis” would be a positive step.

5. Conclusion and Discussion
In conclusion, the areas with high and very high landslide risk in the Province of Kilis are generally mountainous areas and partially slopes with an elevation above 690 m and a slope above 14° and northern and sometimes southern exposure consisting of volcanite and resistant sedimentary rocks. The rainfall is above 500-600 mm in the said areas and the vegetation cover is usually naked and sometimes moderately dense. Previous studies have presented similar results (Iverson, Reid and Lahusen, 1997; Ayalew and Yamagishi, 2004; El Khattabi and Carlier, 2004; Gokceoglu, Sönmez, Nefeslioglu, Duman and Can, 2005; Sidle and Ochiai, 2006; Lee and Pradhan, 2007; Gökçe, Özden and Demir, 2008; Akgun, Dag and Bulut, 2008; Intarawichian, 2008; Khanh, 2009; Pradhan, 2011; Ozdemir and Altural, 2013).
The landslide risk is very-high and high in 14% of the Province of Kilis. Local administrators in the Province should consider these sites where the landslide risk is very high during land use (settlement, farmland, etc.) planning. Indeed, landslides are disasters which may potentially cause losses of life and property. Previous studies have presented similar results for the relationship between landslides and land use (Nagarajan, Roy, Vinod, Mukherjee and Khire, 2000; Dai et al., 2001; Kanungo, Arora, Sarkar and Gupta, 2006; AFAD, 2015). Another point to consider is that the naked fields in the Province (especially the section in the West of Afrin Valley) should be planted with species suitable for the local ecosystem as soon as possible (Çelik and Gülersoy, 2013). On the other hand, the results achieved and the maps produced in this study can help planners and engineers in future development and land-use planning for the Province of Kilis. The foundation of “the Natural Disaster Planning Center of the Province of Kilis” to carry out above mentioned activities would be a positive step.
