Analysis of landslide temporal characteristics based on 50 years of landslide disaster data in Fujian Province
Fujian Province,with its numerous mountainous regions and plentiful annual rainfall,frequently experi-ences landslide disasters triggered by rainfall.This paper presents data from landslide disasters of Fujian Province from 1969 to 2018,extracts information on the date and spatial locations of these landslides,develops a temporal se-ries model,and analyzes the temporal patterns of landslides in the province over the past 50 years.The results indi-cate that the ARIMA(1,2,1)time series model,constructed based on simulated disaster data from Fujian Province and with a four-year cycle,can effectively predict the annual frequency of collapses landslides in Fujian Province.Through Verified by real survey data,the error is within±10 times.
