Spatiotemporal distribution of landslide disasters and analysis of disaster pregnancy background in Duilongdeqing District,Lhasa City
The geological disasters in Xizang are numerous and widespread,and the disaster prevention situation is very challenging.To explore the background of landslide formation in alpine and high-altitude areas,this article takes the landslide in Duilong,Deqing District as the research object,and syestematically summarizes and analyzes the tem-poral and spatial distribution of landslide disasters in the study area,and focuses on analyzing the correlation between the development and distribution of landslides and the influencing factors.The results show that there are 16 landslide disasters in Duilong,Deqing District,which are mainly small-scale,and mainly occur from July to August,and have the characteristics of belt-like distribution along river valleys and fault structures.The slippery strata in the area pro-vide a material basis for the formation of landslides.The topography,geological structure,slope structure,river dis-tance,and human engineering activities have a good correlation with landslides,which are important influencing fac-tors for landslide formation.The formation of landslides is a process of comprehensive action of various factors,and the research has further deepened the understanding of landslide disaster conditions in alpine and high-altitude areas,which can provide a reference for theprevention and control of disasters in the future.
