Nghiên cứu xây dựng bản đồ phân vùng nguy cơ sạt lở đất cho khu vực miền núi tỉnh Quảng Nam

Abstract

In the past ten years, natural disasters have occurred more frequently and severely in both frequency and intensity, especially flash floods and landslides, which have surpassed our forecasting ability. These kinds of natural disasters are responsible for the most unexpected and unpredictable deadly consequences. It is necessary and urgent to conduct a study to patriation the risk of landslides, which allows us to be more proactive in terms of disaster prevention, planning infrastructure, and population arrangement. In this article, the authors introduce the method of landslide risk map based on the integration of the Analytic Hierarchy Process (AHP), Geographic Information System (GIS), and database of natural conditions including topography, geomorphology, geology, hydrogeology, hydrometeorology, land cover, etc. As a result, the high-risk landslide areas that directly affect residents were identified. This crucial information is effective practically for the authorities and people of Quang Nam province.
