Abstract

Abstract: The temporal and spatial distribution characteristics of geological disasters in the middle and upper reaches of Hanjiang River Basin were studied, and the hidden trouble points of geological disasters, slope, elevation, precipitation and human activity indicators were selected to evaluate the susceptibility zoning. The results showed that the development type of geological disasters in the middle and upper reaches of Hanjiang River Basin was mainly landslide, accounting for 77.85%, and the development of land subsidence was the least, accounting for only 0.06%. From 2000 to 2021, the interannual changes of the total number of geological disasters and the number of various types of geological disasters were not large, and the overall trend was a fluctuating downward trend. The development of geological disasters in the middle and upper reaches of Hanjiang River Basin was mainly concentrated in the northern and southern mountains and river valleys in Shaanxi Province, and it was closely related to natural conditions such as the landform. The susceptibility of geological disasters was divided into four levels. The non-susceptible zone accounted for the largest proportion of the total area at 42.36%, followed by the low-susceptibility zone at 25.64%, the moderate-susceptibility zone at 25.08%, and the high-susceptibility zone at 6.92%. In general, the probability of geological disasters in the middle and upper reaches of Hanjiang River basin was low.

Key words: geological hazards, susceptibility, temporal and spatial distribution, Hanjiang River Basin, the middle and upper reaches
