摘要

Based on typical historic landslide disasters in the Three Gorges Reservoir, in this short communication, the most important factors that are likely to induce landslides in the reservoir region were explored, and the new trends of landslide disasters after impoundment of the reservoir region were comprehensively analyzed. In summary, although most landslide incidents along the banks of the Three Gorges Reservoir Region have been induced by the combined effects of rainfall and changes in water-level after impoundment of the reservoir, people activity of production and livelihood forment and aggravate development of landslide disasters. Finally, the new reflections were proposed for addressing problems that occurred related to landslide prevention and disaster management after reservoir impoundment.
