Exploration of Technical Pathways for Urban Geological Disaster Prevention and Control Zoning in High Mountain Gorge Areas:A Case Study of Bayi District,Nyingchi City
Geological disasters are notoriously difficult to predict,especially in high mountain gorge areas,where they are more prevalent.Assessing the susceptibility to geological disasters and delineating prevention and control zones in urban areas within high mountain gorge regions is both urgently needed and of significant importance.Bayi District serves as a quintessential example of urban settlements in high mountain gorge areas.This study established an evaluation system for the susceptibility to geological disasters based on 16 indicators encompassing natural and anthropogenic factors such as topography,geology,meteorology,hydrology,vegetation,soil,and human activities.Subsequently,prevention and control zoning were carried out,taking into account Bayi District's geological environment and socioeconomic development level.The goal is to provide foundational decision-making support for land planning,resident relocation for disaster avoidance,engineering project planning to avoid hazards,and the formulation of preemptive measures for major geological disaster monitoring and early warning in urban areas prone to sudden and frequent geological disasters within high mountain gorge regions.
