Response: Commentary: The Impact of Climate Change on Landslides in Southeastern of High-Latitude Permafrost Regions of China

“…The results show that permafrost melting, and seasonal concentrated precipitation are the main causes of landslide movement (Shan et al, 2015). Juanico (2016) believes that human engineering activities, rapid population growth, rapid urbanization, and an urban heat island effect in Sunwu, near the study area, may be important reasons for the increase in air temperature in the study area. To improve the problems mentioned above, the research team installed meteorological stations near the study area, and, combined with data from the National Meteorological Station on surface temperature in the Sunwu area and MODIS data, it was found that the increasing trend of surface temperature obtained from the National Meteorological Station in Sunwu was higher than that obtained from the MODIS data, which may be due to the influence of the urban heat island effect and human activities on the surface temperature observation points of the National Meteorological Station in Sunwu.…”

“…In addition, although the development of primary industries in the Sunwu area will cause damage to some areas, there are few population activities near the study area, and land for agriculture and forestry is scarce, so the development of primary industries has relatively little impact on the environment of the study area. Juanico (2016) believes that human activities can lead to landslides. In addition to ongoing construction works, vehicle vibrations along the highway may generate enough power to trigger landslides in previously undisturbed areas (Moreiras, 2004).…”

“…In addition, through the investigation, it was found that for the slope section in the non-frozen area, the construction of a highway will disturb the original soil structure and cause new landslides, and for the old landslide area it will cause the old landslide to slide again (Shi et al, 2014;Wang et al, 2019;Guo et al, 2021;Shan et al, 2021). Juanico (2016) believes that the growth process of human settlements can directly or indirectly induce geomorphic evolution on a local scale, and greenhouse gas emissions from industrial production leads to climate warming, which may increase the speed of geomorphic processes such as landslides.…”
