Research on the Influencing Factors of the Spatial Distribution of Geological Disaster Points in Qiandongnan Prefecture
In this paper,five factors were selected,including elevation,slope,land use,river system and road,to study the influencing factors of the spatial distribution of six types of geological disaster points in Qiandongnan Prefecture,the results show that the density of disaster points in the elevation range of 91 m～500 m is the highest,and the number of disaster points in the elevation range of 500 m～1 000 m is the largest,and most of the geological disaster points are located in areas with large slopes,and human activity,river system and road have a certain control effect on the spatial distribution of geological disaster points.
