APPLICATION OF WEIGHTED MODEL FOR ESTABLISHING LANDSLIDE ZONES MAP IN THAI NGUYEN PROVINCE

Abstract

Recently, the impacts of climate change have emerged in many types of dangerous natural disasters, causing serious harm to socio -economic development and human life. Thai Nguyen is a midland and mountainous province with quite high rainfall, so flash floods and landslides often occur. By actual survey, combined with satellite image interpretation, we have analyzed the impact factors, built component maps of the criteria affecting the phenomenon of landslides. Using weighted modeling method, we have established map of landslide zone for Thai Nguyen province. The construction of a map of landslide zones in Thai Nguyen province is very necessary, it is contribed to warn and minimize natural disasters. The map of landslide zone will be the basis for spatial planning, population distribution, infrastructure development and natural disaster prevention, making an important contribution to ensuring social -economic sustainable development in Thai Nguyen province in a sustainable manner.
