The influence of land use and land cover change on landslide susceptibility: a case study in Zhushan Town, Xuan'en County (Hubei, China)

“…The slope unit can be drawn manually from topographic maps or can be delineated automatically using specialized software (Alvioli et al, 2016). According to the prevalent methods provided by the literature (Xie et al, 2004;Reichenbach et al, 2014;Schlögel et al, 2018), the slope units of the study area were partitioned using a ArcGIS-based hydrologic analysis method. Slope units were generated in steps as follows: (i) preparing the reverse digital elevation model (DEM) by subtracting the original DEM from the highest elevation of the study area; (ii) filling the original and the reverse DEM, respectively; (iii) extracting the surface water flow direction to distinguish areas with extremely rapid changes in surface morphology; (iv) establishing the stream link for obtaining the valley lines and ridge lines; (v) delineating the slope units based on the valley and ridgelines.…”

“…The large-scale engineering infrastructures can change the initial geological conditions, which can influence slope stability. In areas with abundant runoff, reservoir construction is the most common infrastructure development activity to utilize water resources, which significantly affects landslides (Iqbal et al, 2018), such as in the case of the Three Gorges Reservoir in China (Huang et al, 2017;Wang et al, 2018;Zhou et al, 2018). To see the effect of the Shuanglong Lake Reservoir construction on landslides, we prepared the distance to the reservoir (Fig.…”

“…Moreover, some studies have indicated that human-induced land use and land cover change (LUCC) contributes significantly to the initiation and reactivation of landslides (Guillard and Zêzere, L. Chen et al: The influence of land use and land cover change on landslide susceptibility 2012; Galve et al, 2015;Meneses et al, 2019), especially in populated regions, where landslides represent a major risk to infrastructure, human settlements and people (Pinyol et al, 2012;Abancó and Hürlimann, 2014). So this factor should not be ignored in the landslide risk reduction process, particularly against the background of adaptation to sustainable natural hazard risk management (Promper et al, 2015;Wang et al, 2018).…”
