考虑到土耳其自然灾害对人造结构的破坏，滑坡是仅次于地震的第二大灾害。为此，自1998年以来，开展了一项名为“土耳其滑坡清查项目”的大规模研究。在该项目期间，进行了一些特殊、敏感性、危害和风险评估。在这项研究中，滑坡易感性地图的一部分，构造Kelkit山谷在土耳其中部北部，采用二元逻辑回归分析。为了获得最适当的结果，还进行了一些敏感性分析。为此，考虑到本研究中所使用的条件因素和适用于训练数据集的采样策略，构建了四个不同的数据集。作为分析的结果，通过使用连续地形参数和岩性虚拟变量一起实施的数据集，以及从种子细胞中随机抽取50%的训练数据集，获得了最合适的结果。正确的分类百分比和均方根误差（RMSE）值的验证数据的情况下，估计为84.16%和0.36，分别。这一预测能力表明，本研究论文中产生的滑坡敏感性图可用于该地区的保护和缓解措施的规划。
Considering damage to man-made structures by natural hazards in Turkey, landslides are the second most important hazard after earthquakes. For this reason, a large-scale study titled Turkish Landslide Inventory Project, has been carried out since 1998. During this project, some special, susceptibility, hazard and risk assessments have been performed. In this study, a landslide susceptibility map of a part of tectonic Kelkit Valley in the north of central Turkey was produced, employing binary logistic regression analyses. To achieve the most appropriate results some sensitivity analyses were also carried out. For this purpose, four different data sets were constructed considering conditioning factors used and sampling strategies applied for the training data sets in this study. As a consequence of the analyses, the most proper outcomes were obtained by using the data set in which continuous topographical parameters and lithological dummy variables were implemented together and 50% of training data set was taken from seed cells at random. Correct classification percentage and Root Mean Square Error (RMSE) values for the validation data for that case were estimated as 84.16% and 0.36, respectively. This prediction capability shows that the landslide susceptibility map produced in this research paper can be used for the planning of protective and mitigation measures in the region.
