Abstract

The paper considers the outcome of multi-criteria analysis of landslide susceptibility on the NW outskirts of Fruska Gora Mountain, Serbia. The area of the interest is known for landslide occurrences, and to focus on the most affected areas, it was necessary to consider some principal factors (lithology, slope inclination, rainfall, erosion, vegetation, altitude and slope aspect) and sort them by their importance to the phenomena. Prior to any criteria assessment, available data records had been assembled and refashioned as raster datasets. Thereafter, the criteria arising from an analytical hierarchy process (AHP) provided their weights of preference in the final model. In addition, the model was analyzed for the information gain and classified in accordance to the optimal informativeness. Being tailored in the context of raster modelling, aided by the GIS spatial tools, our result gained substantial correlation to the control reference map (a digital photo-geological interpretation map of active and potential landslides).

基于层次分析法的地质环境因素对滑坡易感性的影响——以Fruška Gora山为例

本文考虑了塞尔维亚Fruska Gora山西北郊滑坡易感性的多准则分析结果。该地区以滑坡事件而闻名，为了关注受影响最严重的地区，有必要考虑一些主要因素(岩性、坡度、降雨、侵蚀、植被、海拔和坡向)，并根据它们对现象的重要性对它们进行分类。在任何标准评估之前，可用的数据记录已被组装并重新塑造为栅格数据集。然后，从层次分析法(AHP)中产生的标准在最终模型中提供了它们的偏好权重。此外，对模型的信息增益进行分析，并根据最优信息量进行分类。在栅格建模的背景下，在GIS空间工具的帮助下，我们的结果与对照参考地图(活跃和潜在滑坡的数字照片地质解释地图)有很大的相关性。
