摘要: Human activities are important factors that trigger frequent occurrences of landslides; thus, for landslide control, it is critical to determine the influence human activity on occurrence probability. The Three Gorges area a region in world typically experiences serious disasters and activities. objective this work employ as an example reveal impact dynamic development susceptibility from 2010 2019. Some new viewpoints suggested five aspects: (1) High-precision maps generated by combination multiresolution segmentation convolutional neural network algorithms. Moreover, rules 2019 revealed. (2) change study was mainly caused combined action rainfall activity. fluctuation reservoir water level had less susceptibility. (3) activities, especially road construction, farmland appropriation building agricultural reclamation, cultivation irrigation, initiation commercial planting, urban expansion, large-scale deforestation, may dramatically increase (4) e.g., conversion forestry, artificial recovery natural vegetation, later periods obviously reduce (5) causes mechanisms influencing proposed, including transpiration anchorage plants, slope reinforcement plant roots, destruction stress equilibrium, soil erosion.
