Abstract

Landslides and avalanches are common geologic hazards and the most destructive natural disasters at home and abroad. Therefore, utilizing different models and methods to explain the extent of landslides and avalanches is one of the basic methods to prevent and reduce possible disasters. Remote sensing probing technique has become one of the indispensable techniques for the investigation of geological disasters in domestic and foreign regions. In this study, SPOT 5 satellite images of the study area were selected and the normalized vegetation index (NDVI) and MATLAB were used to calculate the difference and to classify the vegetation area and landslide exposure area. The size of the exposed landslide area can be quickly determined to facilitate stable tracking of large subsidence areas. Management and large-scale settlement notification can also be used as basic information for the research and application of large-scale landslides in sensitive geological hazards in mountainous areas.

The study found that from 2010 to 2011, the exposed ground area and destructive collapse area of landslides showed an increasing trend. The rapid response to monitoring collapse areas can be used as the basic area for investigating large-scale collapse areas in mountainous areas.
