RESEARCH ON LANDSLIDE RISKS IN BA BE NATIONAL PARK BY TELE-EXPLORATION AND GIS TECHNOLOGY

Abstract

              Ba Be National Park is one of the large biosphere reserve regions in Vietnam. The mountainous and river terrain accounts for a large area along with the humid tropical climate, which has made Ba Be National Park be one of the typical places affected by the soil erosion and landslide with increasing frequency over each year. The article refers to the application of teleexploration technology and geographic information system to build maps for analyzing the correlation between such factors as slope, elevation, flow, catchment vegetation coverage and risks for soil erosion and landslide. The research is the basis for the assessment, prediction of landslide in Ba Be National Park in order to offer solutions to prevent, minimize soil erosion and landslide in consistent with the situation of different regions and terrains.
